Pierścień naczyniowy
Patofizjologia i mechanizm

Pierścień naczyniowy to rzadka wrodzona anomalia układu naczyniowego, polegająca na nieprawidłowej konfiguracji łuku aorty lub naczyń okołotchawiczych, które całkowicie lub częściowo otaczają tchawicę i przełyk, powodując ich ucisk. Najczęstszym objawowym typem jest podwójny łuk aorty, gdzie aorta wstępująca dzieli się na prawy i lewy łuk, otaczając drogi oddechowe i przełyk. Objawy kliniczne zależą od stopnia ucisku i obejmują stridor, duszność, szczekający kaszel, nawracające infekcje dróg oddechowych oraz dysfagię i zaburzenia karmienia. Diagnostyka i zrozumienie embriologii łuku aorty są kluczowe, gdyż pierścień powstaje na skutek nieprawidłowej regresji jednego z sześciu embrionalnych łuków skrzelowych. Nieleczone pierścienie mogą prowadzić do poważnych powikłań, takich jak tracheomalacja, epizody hipoksji, a nawet nagła śmierć.

Patogeneza pierścienia naczyniowego

Pierścień naczyniowy to rzadka wrodzona anomalia układu naczyniowego, w której nieprawidłowa konfiguracja łuku aorty lub związanych z nim naczyń otacza tchawicę i przełyk, tworząc całkowity lub niecałkowity pierścień wokół tych struktur. Anomalia ta może powodować ucisk na drogi oddechowe, przełyk lub obie te struktury jednocześnie, prowadząc do objawów oddechowych i pokarmowych.12

Rozwój embriologiczny

Zrozumienie rozwoju embriologicznego łuku aorty jest kluczowe dla zrozumienia powstawania pierścieni naczyniowych. Na początku czwartego tygodnia embriogenezy łuk aorty rozwija się z sześciu symetrycznych par naczyń łukowych aorty i parzystych aort grzbietowych. W ciągu kolejnych tygodni embriogenezy, remodeling i przekształcenie tych struktur prowadzi do powstania prawidłowego lewego łuku aorty.34

Różne formy pierścieni naczyniowych powstają bardzo wcześnie w rozwoju embriologicznym. Są one wynikiem nieprawidłowej lub niekompletnej regresji jednego z sześciu embrionalnych łuków skrzelowych. Nieprawidłowy rozwój łuku występuje, gdy jedna lub więcej z koniecznych inwolucji lub innych zmian w embrionalnych strukturach łuku nie zachodzi.56

Mechanizmy powstawania pierścieni naczyniowych

Pierścień naczyniowy tworzy się, gdy występuje brak regresji lub przetrwanie części łuku aorty, która normalnie powinna ulec zanikowi. Klasyczne pierścienie naczyniowe powstają w wyniku zaburzeń w czterech kluczowych punktach normalnego rozwoju:78

  • Pierwszy punkt dotyczy prawej aorty grzbietowej, która normalnie ulega regresji, ale jeśli przetrwa, rozwija się podwójny łuk aorty
  • Drugi punkt dotyczy prawego czwartego łuku aorty, który normalnie przetrwa i rozwija się w proksymalną część tętnicy podobojczykowej po prawej stronie
  • Trzeci punkt dotyczy lewej aorty grzbietowej, która normalnie przetrwa, tworząc lewą aortę zstępującą
  • Czwarty punkt dotyczy lewego czwartego łuku, który normalnie przetrwa i rozwija się w część lewego łuku aorty

9

Najczęstszym objawowym pierścieniem naczyniowym jest podwójny łuk aorty, który powstaje w wyniku przetrwania prawej aorty grzbietowej. Prawy i lewy łuk aorty otaczają tchawicę i przełyk, tworząc pierścień wokół tych struktur i uciskając je w różnym stopniu.1011

W przypadku podwójnego łuku aorty, aorta wstępująca dzieli się na prawy i lewy łuk poprzeczny. Prawy łuk poprzeczny przebiega nad prawym oskrzelem głównym, podczas gdy lewy łuk aorty znajduje się nad lewym. Ponieważ aorta zwykle zstępuje w kierunku lewej strony ciała, prawy łuk aorty przebiega do tyłu i wnika do niej. Dalsze gałęzie pochodzą z łuków poprzecznych: lewa tętnica szyjna wspólna i podobojczykowa z lewego łuku aorty, a prawa tętnica szyjna wspólna i prawa podobojczykowa z prawego łuku.1213

Rodzaje pierścieni naczyniowych

Pierścienie naczyniowe można sklasyfikować jako całkowite (kompletne) lub niecałkowite (niekompletne):1415

  • Kompletne pierścienie naczyniowe – całkowicie otaczają tchawicę i przełyk strukturami naczyniowymi; zazwyczaj są objawowe
  • Niekompletne pierścienie naczyniowe – nie otaczają całkowicie tchawicy i przełyku; zazwyczaj są bezobjawowe

1617

Najczęstsze typy pierścieni naczyniowych to:1819

20

Mechanizm powstawania objawów

Pierścienie naczyniowe powodują objawy poprzez bezpośredni ucisk na tchawicę i/lub przełyk. Nasilenie objawów i czas ich wystąpienia są bezpośrednio proporcjonalne do stopnia ucisku spowodowanego przez pierścień.2122

Mechanizm ucisku dróg oddechowych

Objawy ze strony układu oddechowego są spowodowane bezpośrednim uciskiem tchawicy lub oskrzeli przez nieprawidłowe naczynia. Ucisk ten może prowadzić do różnego stopnia zwężenia dróg oddechowych, co powoduje:2324

  • Stridor (świszczący oddech)
  • Duszność
  • Szczekający kaszel
  • Nawracające infekcje dróg oddechowych
  • Epizody bezdechu

2526

Co istotne, aktywności zwiększające zapotrzebowanie kardiologiczne (np. karmienie, płacz) prowadzą do przekrwienia naczyń, pogłębiając ucisk tchawicy i przełyku.27

W przypadku niemowląt z podwójnym łukiem aorty, często występuje stridor, duszność i szczekający kaszel – wszystkie te objawy są spowodowane uciskiem na tchawicę. W grupie pierścieni naczyniowych i pętli jako całości, objawy oddechowe dominują w początkowej prezentacji. Około 70-90% pacjentów będzie miało objawy oddechowe, a stridor występuje prawie we wszystkich przypadkach.2829

Mechanizm ucisku przełyku

Ucisk na przełyk może prowadzić do następujących objawów:3031

  • Trudności w połykaniu (dysfagia)
  • Krztuszenie się podczas jedzenia
  • Wymioty
  • Zaburzenia wzrostu związane z problemami z karmieniem

32

Objawy pierścienia naczyniowego z prawym łukiem aorty i nieprawidłową lewą tętnicą podobojczykową zależą od tego, czy pierścień naczyniowy jest luźny czy ciasny.33

Nasilenie objawów

Nasilenie objawów zależy od stopnia ucisku tchawicy i przełyku. Łagodny ucisk tchawicy może być bezobjawowy. Bardziej znaczące zaangażowanie u młodszych pacjentów może objawiać się stridorem, dusznością i szczekającym kaszlem, które nasilają się podczas karmienia lub wysiłku.3435

Osoby z większym uciskiem najprawdopodobniej będą prezentować objawy wcześniej w życiu. W przeciwieństwie do stridoru spowodowanego laryngomalacją, stridor związany z anomalią pierścienia naczyniowego nie pogarsza się, gdy niemowlę jest ułożone w pozycji na wznak lub gdy płacze i napina się. Stridor spowodowany anomaliami pierścienia naczyniowego pogarsza się podczas karmienia, podobnie jak w przypadku tracheomalacji i przetoki tchawiczo-przełykowej.3637

Powikłania i następstwa pierścienia naczyniowego

Nieleczony pierścień naczyniowy może prowadzić do różnych powikłań, które wynikają z długotrwałego ucisku na tchawicę i przełyk.38

Powikłania ze strony układu oddechowego

Długotrwały ucisk tchawicy może prowadzić do:3940

  • Tracheomalacji – osłabienia ścian tchawicy, co powoduje trudności z oddychaniem
  • Częstych infekcji dolnych dróg oddechowych – ze względu na trudności z usuwaniem wydzieliny z obszaru poniżej uciśniętej części tchawicy
  • Tracheobronchiomalacji – wymagającej dodatkowych interwencji, takich jak aortopeksja

4142

U niemowląt ucisk tchawicy może prowadzić do tracheomalacji i związanych z nią trudności w oddychaniu. Starsze dzieci często prezentują częste infekcje dolnych dróg oddechowych, ponieważ mają trudności z usuwaniem wydzieliny z obszaru poniżej uciśniętej części tchawicy.43

W przypadkach mniej nasilonego ucisku tchawicy, diagnoza anomalii podwójnego łuku aorty może być postawiona w wieku dorosłym. Literatura opisuje również niezwykle rzadkie przypadki dorosłych z podwójnym łukiem aorty, u których objawy naśladują przewlekłą astmę.44

Potencjalne powikłania nieleczonego pierścienia naczyniowego

Nieleczone objawowe pierścienie naczyniowe mogą prowadzić do:4546

  • Epizodów hipoksji
  • Nagłej śmierci
  • Tętniaka
  • Rozwarstwienia aorty
  • Erozji aorty do tchawicy lub przełyku

47

Z tego powodu objawowe pierścienie naczyniowe są operowane chirurgicznie w pierwszym roku życia, aby uniknąć tych powikłań.4849

Powikłania związane z leczeniem

Główne mechanizmy niepowodzenia leczenia można ogólnie skategoryzować jako:50

  • Utrzymujący się ucisk naczyniowy
  • Rozwój zwężającej tkanki bliznowatej ponownie tworzącej pierścień naczyniowy
  • Tracheobronchomalacja
  • Kombinacja powyższych czynników

51

Utrzymujący się ucisk naczyniowy może być związany z nieprawidłową tętnicą podobojczykową, jeśli wcześniejsza operacja polegała jedynie na przecięciu więzadła tętniczego w celu uwolnienia pierścienia naczyniowego. Dla tych pacjentów standardem jest ponowna operacja z transpozycją tętnicy podobojczykowej do tętnicy szyjnej.52

Nierozpoznanie aorty okrężnej lub aorty zstępującej w linii środkowej podczas początkowej operacji może skutkować utrzymującymi się objawami, a rekonstrukcja aorty może być konieczna. Rozwój tkanki bliznowatej w miejscu, gdzie wcześniej przecięto więzadło tętnicze lub dodatkowy łuk aorty, może prowadzić do ponownego utworzenia wcześniej naprawionego pierścienia naczyniowego.53

W celu uniknięcia tych ponownych operacji, podejście do początkowej operacji ewoluowało, aby obejmować liberalne stosowanie tracheobronchoopeksji pod kontrolą bronchoskopową u pacjentów z tracheobronchomalacją i znaczącymi objawami oddechowymi.54

Skojarzenia pierścienia naczyniowego z innymi anomaliami

Pierścienie naczyniowe mogą być skojarzone z innymi wrodzonymi wadami serca, w szczególności z anomaliami stożkowo-pniowymi (tetralogia Fallota, przełożenie wielkich pni tętniczych, wspólny pień tętniczy) oraz z zespołami, w tym z delecją 22q11.5556

Wady serca współwystępujące z pierścieniem naczyniowym

Podwójny łuk aorty jest czasami skojarzony z innymi wrodzonymi wadami serca, w tym z:57

  • Ubytkami przegrody międzykomorowej – u około 10% pacjentów
  • Ubytkami przegrody międzyprzedsionkowej – u około 5% pacjentów
  • Tetralogią Fallota – u około 4% pacjentów
  • Rzadkimi przypadkami z pniem wspólnym i przełożeniem wielkich naczyń

58

Pierścienie naczyniowe obejmują tylko 1-3% wszystkich wrodzonych wad serca. Niektóre pierścienie naczyniowe są związane z innymi wrodzonymi wadami serca, podczas gdy inne są izolowanymi defektami. Anomalie tchawiczo-oskrzelowe są rzadko obserwowane w pierścieniach naczyniowych, ale są powszechne w pętlach tętnicy płucnej.59

Pierścień naczyniowy a zespoły genetyczne

Dokładna przyczyna pierścienia naczyniowego (ani żadnego innego pierścienia naczyniowego) nie jest znana. W literaturze opisano związek prawego łuku aorty i podwójnego łuku aorty z delecją 22q11. Istnieje pewne powiązanie podwójnego łuku aorty z trisomią 21 i trisomią 18. Lewy łuk aorty z nieprawidłową (za przełykową) prawą tętnicą podobojczykową nie jest pierścieniem, ale jest silnie związany z trisomią 21.6061

Pierścienie naczyniowe występują w około 1 na 2500 urodzeń, z większą częstością u chłopców. Są zwykle izolowane, ale mogą również występować z innymi wrodzonymi wadami serca. U niektórych pacjentów mogą występować powiązane schorzenia genetyczne, z których najczęstszym jest zespół delecji 22q11 (znany również jako zespół DiGeorge’a).62

Rzadkie przypadki współwystępowania

Opisano przypadek noworodka z zespołem HDR i pierścieniem naczyniowym, które mogły być spowodowane nową mutacją ramki odczytu w genie GATA3. Pierścień naczyniowy nie był wcześniej zgłaszany u pacjentów z zespołem HDR związanym z GATA3. Jest to pierwszy raport o przypadku zespołu HDR z jednoczesnym pierścieniem naczyniowym.63

Relacja między mutacjami GATA3 a pierścieniem naczyniowym pozostaje nieznana, ale spekuluje się, że haploinsuficjencja GATA3 przyczynia się do rozwoju pierścienia naczyniowego, a także objawów zespołu HDR.64

Leczenie i rokowanie

Leczenie chirurgiczne jest wskazane u wszystkich objawowych pacjentów z pierścieniem naczyniowym. Aby uniknąć poważnych powikłań, operacja nie powinna być opóźniana, szczególnie u pacjentów z objawami ucisku dróg oddechowych. Osoby, które nie mają objawów pierścienia naczyniowego, mogą nie wymagać interwencji chirurgicznej.6566

Podejście chirurgiczne

Celem leczenia chirurgicznego u pacjentów z podwójnym łukiem aorty jest przecięcie mniejszego z dwóch łuków w miejscu, które nie zagraża przepływowi krwi do naczyń głowowych.6768

U pacjentów z prawostronnym łukiem aorty przecinane jest więzadło tętnicze. Pacjenci z nieprawidłową lewą tętnicą podobojczykową i uchyłkiem Kommerella mogą dodatkowo wymagać resekcji uchyłka i reimplantacji lewej tętnicy podobojczykowej do lewej tętnicy szyjnej jako operacji pierwotnej.69

Interwencje chirurgiczne mogą obejmować:70

  • Torakotomię (dostęp do ściany klatki piersiowej z boku między żebrami)
  • Sternotomię (przecięcie mostka w celu uzyskania dostępu do jamy klatki piersiowej)

71

Techniki resekcji pierścienia naczyniowego mogą obejmować:72

  • Usunięcie naczyń lub więzadeł
  • Reimplantację nieprawidłowej tętnicy podobojczykowej
  • Zmianę pozycji aorty

73

Wyniki leczenia i rokowanie

Wyniki chirurgicznej naprawy pierścieni naczyniowych są doskonałe i minimalizują powikłania związane z przewlekłym uciskiem dróg oddechowych i przełyku.74

U dzieci z pierścieniami naczyniowymi korekcja chirurgiczna nie jest związana z żadną śmiertelnością. Rzadkie zgłaszane przypadki śmiertelności w pierścieniu naczyniowym były związane z innymi wrodzonymi wadami serca lub podstawową patologią płucną.75

Ponad 70% pacjentów staje się bezobjawowych po roku od korekcji chirurgicznej. Jednakże objawy oddechowe mogą utrzymywać się przez cztery do sześciu miesięcy po operacji.76

Potrzeba ponownej operacji jest bardzo niska (8%), a najczęstsze przyczyny to utrzymywanie się uchyłka, okrężny łuk aorty, bliznowacenie i tracheobronchomalacja wymagające aortopeksji.77

Chirurgiczna naprawa pierścieni naczyniowych wiąże się z bardzo niskim ryzykiem zachorowalności i śmiertelności, z korzystnymi średnio- i długoterminowymi wynikami. Obliteracja uchyłka Kommerella i reimplantacja tętnicy podobojczykowej osiągają dobre wyniki w eliminacji objawów oddechowych i przełykowych po naprawie pierścienia naczyniowego.78

Wyniki po operacji są zadowalające i prowadzą do bezproblemowego długoterminowego przeżycia. Celem operacji jest złagodzenie ucisku na tchawicę i/lub przełyk poprzez przecięcie przemieszczonego naczynia przy jednoczesnym zapewnieniu wystarczającego przepływu krwi w kierunku głowy.79

Wskaźniki chirurgiczne ogólnie są bardzo dobre (70-90% ustąpienia objawów). Dysfagia prawie zawsze ustępuje, a uporczywe problemy po początkowej naprawie są często związane z anomaliami tchawicy.80

    https://emedicine.medscape.com/article/426233-overview
    A vascular ring is an unusual congenital condition in which the anomalous configuration of the arch, associated vessels, or both surrounds the trachea and esophagus, forming a complete or incomplete ring around them. […] In spite of the significant variability in this group of structural abnormalities of the aortic arch, they all possess a common feature: They all produce some degree of compression on the major airway structures, the esophagus, or both. The location and severity of compression varies with the configuration of the lesion. Individuals with anomalies producing more severe compression are likely to present earlier in life. […] Surgical division of a vascular ring is indicated in all symptomatic patients. To avoid serious complications, surgery should not be delayed, especially in patients with symptoms of airway compression. Individuals who have no symptoms from a vascular ring may not require surgical intervention. Surgical repairs in most cases can be performed successfully and without long-term morbidity.

    Vascular ring refers to a congenital anomaly where vascular structures encircle and compress the trachea and esophagus, leading to respiratory and gastrointestinal symptoms. […] The vascular ring is formed when there is a failure of the regression or persistence of some part of the aortic arch. A double aortic arch is formed when the fourth aortic arches persist. The ascending aorta and transverse aortic arch compress the trachea, whereas the right aortic arch compresses the esophagus. […] The ascending aorta further divides into right and left transverse arches in DAA. The right transverse arch courses over the right mainstem bronchus, whereas the left aortic arch is over the left. Because the aorta usually descends towards the left side of the body, the right aortic arch goes posteriorly and inserts into it. Further branches originate from the transverse arches: the left common carotid and subclavian from the left aortic arch and the right common carotid and right subclavian from the right arch.
  • #3 Vascular rings and slings – UpToDate
    http://www.uptodate.com/contents/vascular-rings
    Vascular rings are congenital anomalies of the aortic arch that result in compression of the tracheobronchial tree and/or esophagus, leading to respiratory and gastrointestinal symptoms. They can be classified as either complete (when both the trachea and esophagus are fully encircled by a vascular anomaly) or incomplete (without full encirclement of both structures). […] Beginning at the fourth week of embryogenesis, the aortic arch develops from six symmetrical paired aortic arch vessels and the paired dorsal aortae. During the next few weeks of embryogenesis, remodeling and rearrangement of these structures result in the formation of the normal left aortic arch.

    A vascular ring is a rare congenital cardiovascular anomaly, which encircles and compresses the trachea or esophagus, or both. […] In this review we discuss the pathophysiology, theoretical embryopathogenesis, diagnostic modalities, and surgical treatment of the different types of vascular ring. Knowledge of the normal embryonic development of the aortic arch and related structures is important for understanding and classifying the various forms of vascular ring. The development of a vascular ring begins with the embryonic aortic arch system. The persistence, involution, or regression of the arches determines the multiple variations of vascular ring. […] For patients with symptoms, surgical division of the vascular ring usually achieves excellent outcomes with marked resolution of symptoms and a low risk of morbidity and mortality. Symptomatic vascular rings require early surgical intervention to prevent prolonged vascular compression of the airway and serious complications.

    Vascular rings and pulmonary slings are congenital anomalies of the aortic arch and pulmonary artery. They are very important but rare causes for common respiratory symptoms, especially in infants. Their etiology is related to abnormal development of the embryonic aortic arches. When the abnormal blood vessels form a ring around the trachea and esophagus, it is termed vascular ring. These rings may be complete or incomplete. The severity of symptoms depends on the degree of compression of the trachea and esophagus. […] Failure of regression or persistence of normally regressed portions will result in one of many vascular rings or a pulmonary artery sling. […] The classic vascular rings will result from disruption at 4 points in the normal development. The first point is at the right dorsal aorta. This normally will regress but if it persists, a double aortic arch will develop. The second point is at the right 4th aortic arch. This normally will persist and develop into the proximal portion of the subclavian artery on the right. Failure of this to develop will result in the right subclavian artery to arise from the left aortic arch. The third point is at the left dorsal aorta. This normally persists to form the left descending aorta. If this regresses, a right aortic arch will persist. The fourth point is at the left 4th arch. This normally persists and develops into a portion of the left aortic arch. If this regresses, a right aortic arch will persist and the left subclavian will arise from the right arch.

    Vascular rings encompass only 1% to 3% of all congenital heart disease. Some vascular rings are associated with other congenital heart lesions while others are isolated defects. Tracheobronchial anomalies are rarely seen with vascular rings but are common in pulmonary artery slings. […] The most common symptomatic vascular ring is the double aortic arch. This results from persistence of the right dorsal aorta. The right and left aortic arches encircle the trachea and esophagus. The double aortic arch thus forms a ring around the trachea and esophagus compressing both the trachea and esophagus to a variable degree. […] A pulmonary sling is the left pulmonary artery arising from the right pulmonary artery. It is also known as an anomalous pulmonary artery and results from regression/failure of development of the left pulmonary artery.

    Vascular ring refers to a group of anomalies of the aortic arch that cause respiratory symptoms or feeding problems. […] The vascular ring may be divided into two groups, complete (or true) and incomplete. […] Complete vascular ring refers to conditions in which the abnormal vascular structures or their remnants form a complete circle around the trachea and esophagus. […] Incomplete vascular ring refers to vascular anomalies that do not form a complete circle around the trachea and esophagus but do compress the trachea or esophagus. […] Double aortic arch is the most common vascular ring (40%). This anomaly is caused by a failure of regression of both the right and left fourth branchial arches, resulting in right and left aortic arches, respectively. […] The right aortic arch is usually larger than the left arch (seen in 75% of patients), but on rare occasions, partial obstruction or complete atresia of the left arch (with a ligamentous remnant) may occur.

[…] Causes of vascular rings and slings commonly include double aortic arch (the most common symptomatic vascular ring), incomplete double aortic arch, right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum, aberrant right subclavian artery (most common), and pulmonary sling. […] Vascular rings can be classified as complete (mostly symptomatic) or incomplete (mostly asymptomatic).

    A ring is complete or true when there is encirclement on all sides, while it is incomplete or partial when at least one side is not involved. […] The ring may be caused by patent vascular structures, in which case the diagnosis is usually straightforward. However, identifying the ring can be challenging when atretic vessels or the ligamentum arteriosum are involved. […] A right aortic arch occurs in 0.1 % of the population. […] A right aortic arch with an aberrant left subclavian artery is caused by a persistent right fourth arch and regression of the left fourth arch in between the left common carotid and left subclavian arteries. […] A right aortic arch with a retroesophageal left subclavian artery, Kommerell diverticulum and left ductus arteriosus is repaired using a muscle-sparing left thoracotomy.

    The development of multidetector computed tomography has triggered a revolution in the study of the aorta and other large vessels and has replaced angiography in the diagnosis of congenital anomalies of the aortic arch, particularly vascular rings. […] Vascular rings (VR) are congenital developmental abnormalities of the aortic arch consisting of vascular structures that encircle and sometimes compress the airway and esophagus. […] The exact prevalence of VR is unclear because most data have been derived from historical series that collected data on symptomatic patients. […] The most frequent VR are the double aortic arch (DAA) and the right arch with aberrant left subclavian artery (ALSA). […] Congenital heart disease detection has improved in recent decades due to greater diagnostic accuracy in the prenatal and neonatal periods.

    All congenital vascular anomalies that cause compression of the trachea and/or esophagus. […] Severity of symptoms and time of presentation are directly proportional to the tightness of the ring. […] The diverticulum is an important factor in causing compressive symptoms. If there is no diverticulum there is possibly a different etiology for breathing or swallowing issues. […] There are many in cardiothoracic literature who do not see this as a compressive entity and are reluctant to operate and treat an aberrant right subclavian artery. […] The decision for surgery is a joint decision between multiple actors. It will often not be clear that dysphagia or airway difficulty are a direct result of vascular compression. Ultimately, cardiothoracic surgery is responsible to the decision to proceed with treatment but it often involves discussions with pulmonology, cardiology, otolaryngology and the family. […] Surgical outcomes are generally very good (70-90% resolution). Dysphagia almost always resolves and persistent problems after initial repair are often related to tracheal anomalies.

    https://emedicine.medscape.com/article/426233-overview
    A vascular ring is an unusual congenital condition in which the anomalous configuration of the arch, associated vessels, or both surrounds the trachea and esophagus, forming a complete or incomplete ring around them. […] In spite of the significant variability in this group of structural abnormalities of the aortic arch, they all possess a common feature: They all produce some degree of compression on the major airway structures, the esophagus, or both. The location and severity of compression varies with the configuration of the lesion. Individuals with anomalies producing more severe compression are likely to present earlier in life. […] Surgical division of a vascular ring is indicated in all symptomatic patients. To avoid serious complications, surgery should not be delayed, especially in patients with symptoms of airway compression. Individuals who have no symptoms from a vascular ring may not require surgical intervention. Surgical repairs in most cases can be performed successfully and without long-term morbidity.

    http://hawaii.edu/medicine/pediatrics/pedtext/s07c07.html
    In the group of vascular rings and slings as a whole, respiratory symptoms predominate in the initial presentation. The severity of compression determines the severity of symptoms. About 70% to 90% of patients will have respiratory symptoms. Stridor is present in almost all cases. […] The diagnosis of vascular rings is challenging. A high index of suspicion is necessary because of the relatively low incidence of these anomalies in contrast to the common symptoms the patients exhibit. […] Vascular rings are surgically corrected if the patient is symptomatic. If the patient is asymptomatic or has mild symptoms, he/she can be monitored and treated conservatively. Many mild symptoms can resolve with growth. It is however always indicated to surgically correct patients with pulmonary slings, double aortic arch and right arch with a left ligamentum arteriosum upon diagnosis since these patients will progressively become more symptomatic over time.
  • #30 Vascular Ring | Boston Children’s Hospital
    https://www.childrenshospital.org/conditions/vascular-ring
    A vascular ring occurs when a childs aorta the bodys largest blood vessel or its branches form abnormally, so that they encircle and constrict the trachea and usually the esophagus. This compression can cause breathing and swallowing problems. […] Vascular rings are caused by malformed blood vessels. But the vessels themselves arent really the issue, and some people without symptoms may live their entire lives not even realizing that they have a vascular ring. Instead, symptoms occur when a vascular ring puts pressure on a childs esophagus, trachea, or both. […] Normally, the aorta develops from one in a series of symmetrical arches. By the end of the second month of fetal development, the other arches are naturally broken down or formed into arteries. When a vascular ring occurs, certain arches that should have disappeared still remain and form a ring structure.

    Aortic arch anomalies can give rise to vascular rings, a rare vascular anomaly with significant health implications. […] The above embryological knowledge is essential in understanding the formation of vascular rings that can arise from various aortic arch anomalies. […] Since all symptoms result from mechanical compression, there is no role for medical treatment, and surgical correction is the only definitive treatment available with excellent clinical outcomes. […] In children with vascular rings, surgical correction is not associated with any mortality. Rare reported cases of mortality in the vascular ring have been associated with other congenital heart disease or underlying pulmonary pathology. […] More than 70% of patients become asymptomatic after one year after surgical correction. However, respiratory symptoms can persist up to four to six months after surgery. […] The need for reoperation is very low (8%), and the most common reasons for it include persistence of diverticulum, circumflex aortic arch, scarring, and tracheobronchomalacia needing aortopexy.

    For these patients, reoperation with subclavian-to-carotid transposition is standard. […] Failure to recognize a circumflex aorta or midline descending thoracic aorta at the initial operation may result in residual symptoms, and aortic reconstruction may be necessary. […] Development of scar tissue where previously a ligamentum arteriosum or accessory aortic arch has been divided may result in reformation of the previously repaired vascular ring, and this often is apparent on esophagram. […] Finally, the infrequent application of tracheobronchopexy at the time of vascular ring operation appears to be a distinct mechanism of failure. […] In order to avoid these reoperations, our approach at the initial operation has evolved to include liberal use of tracheobronchopexy under bronchoscopic guidance for patients with tracheobronchomalacia and significant respiratory symptoms.

    Vascular rings are congenital abnormalities of the aortic arch-derived vascular and ligamentous structures, which encircle the trachea and oesophagus to varying degrees, resulting in respiratory or feeding difficulties in children. […] A sling is an abnormality of the pulmonary arterial system resulting in airway compression. […] Although several imaging examinations are available for the evaluation of these anomalies, computed tomography (CT) has become the preferred test because of rapid acquisitions, making it feasible to perform the study without sedation or general anaesthesia. […] Imaging plays an important role in the evaluation and management of vascular rings. […] Vascular rings may be associated with congenital abnormalities, particularly conotruncal anomalies (tetralogy, transposition, truncus) and syndromes including 22q11 deletion.

    The vascular ring is formed when there is a failure of the regression or persistence of some part of the aortic arch. A double aortic arch is formed when the fourth aortic arches persist. The ascending aorta and transverse aortic arch compress the trachea, whereas the right aortic arch compresses the esophagus. The right arch is dominant in three-fourths of patients with a double aortic arch. Double aortic arch is sometimes associated with other congenital heart defects, including ventricular septal defects in about 10% of patients, atrial septal defects in about 5% of the patients, tetralogy of Fallot in about 4% of the patients, and rare cases with truncus and transposition of the great vessels. […] DAA’s exact cause is unknown (nor for any other VR). There have been associations of RAA and DAA with 22q11 deletion in the literature. There is some association of DAA with trisomy 21 and trisomy 18. A left aortic arch with aberrant (retro-esophageal) right subclavian artery is not a ring but is highly associated with trisomy 21.

    Vascular rings encompass only 1% to 3% of all congenital heart disease. Some vascular rings are associated with other congenital heart lesions while others are isolated defects. Tracheobronchial anomalies are rarely seen with vascular rings but are common in pulmonary artery slings. […] The most common symptomatic vascular ring is the double aortic arch. This results from persistence of the right dorsal aorta. The right and left aortic arches encircle the trachea and esophagus. The double aortic arch thus forms a ring around the trachea and esophagus compressing both the trachea and esophagus to a variable degree. […] A pulmonary sling is the left pulmonary artery arising from the right pulmonary artery. It is also known as an anomalous pulmonary artery and results from regression/failure of development of the left pulmonary artery.

    A vascular ring occurs when the aorta and its branching blood vessels are improperly formed, causing compression of the trachea and esophagus. Vascular rings occur in approximately 1 in 2,500 births, with a higher prevalence in boys. They are usually isolated, but can also happen with other congenital heart defects. Some patients may have associated genetic conditions, the most common of which is 22q11 deletion syndrome (also known as DiGeorge syndrome). […] If surgery is recommended, the cardiovascular surgeon will decide the best approach after reviewing all imaging. Approaches may include: A thoracotomy (accessing the chest wall from the side between the ribs) or A sternotomy (dividing the breastbone to access the chest cavity). Techniques to resect the vascular ring can include takedown of the vessels or ligaments, re-implanting an abnormal subclavian artery, or re-positioning the aorta.

    HDR syndrome (OMIM #146255) is caused by haploinsufficiency of the GATA3 gene. A vascular ring has not been reported in patients with GATA3-associated HDR syndrome. We report a neonatal case of HDR syndrome and a vascular ring that were possibly due to a novel frameshift mutation in the GATA3 gene. […] A vascular ring, which consists of abnormal blood vessels, is a congenital malformation of the aortic arch and its branches surrounding the trachea and esophagus. To date, a vascular ring has not been reported in patients with GATA3-associated HDR syndrome. […] This is the first case report of HDR syndrome with a concomitant vascular ring. The proband had a novel frameshift mutation in the GATA3 gene. This frameshift mutation leads to disruption of the zinc-finger domain and probably causes haploinsufficiency of GATA3.

    A vascular ring is an unusual congenital condition in which the anomalous configuration of the arch, associated vessels, or both surrounds the trachea and esophagus, forming a complete or incomplete ring around them. […] In spite of the significant variability in this group of structural abnormalities of the aortic arch, they all possess a common feature: They all produce some degree of compression on the major airway structures, the esophagus, or both. The location and severity of compression varies with the configuration of the lesion. Individuals with anomalies producing more severe compression are likely to present earlier in life. […] Surgical division of a vascular ring is indicated in all symptomatic patients. To avoid serious complications, surgery should not be delayed, especially in patients with symptoms of airway compression. Individuals who have no symptoms from a vascular ring may not require surgical intervention. Surgical repairs in most cases can be performed successfully and without long-term morbidity.

    A vascular ring is a rare congenital cardiovascular anomaly, which encircles and compresses the trachea or esophagus, or both. […] In this review we discuss the pathophysiology, theoretical embryopathogenesis, diagnostic modalities, and surgical treatment of the different types of vascular ring. Knowledge of the normal embryonic development of the aortic arch and related structures is important for understanding and classifying the various forms of vascular ring. The development of a vascular ring begins with the embryonic aortic arch system. The persistence, involution, or regression of the arches determines the multiple variations of vascular ring. […] For patients with symptoms, surgical division of the vascular ring usually achieves excellent outcomes with marked resolution of symptoms and a low risk of morbidity and mortality. Symptomatic vascular rings require early surgical intervention to prevent prolonged vascular compression of the airway and serious complications.

    Vascular rings are a group of diagnoses present at birth caused by abnormal development of the brachial arch system, which results in a ring of vessels encircling and constricting the airway and esophagus. […] When there are abnormalities in this process, various types of vascular rings occur. […] There is no known cause of or genetic link for vascular rings. […] Surgical intervention is nearly always recommended to release vascular rings. […] Mayo Clinic pediatric and congenital heart surgeons have conducted retrospective studies on pediatric and adult patients who have undergone surgical correction of vascular rings. „We have found that, in general, surgical repairs have excellent outcomes and minimize complications related to chronic airway and esophageal compression,” says Dr. Stephens.

    Early surgical repair of symptomatic vascular rings is crucial, aiming to relieve the compression while reducing the associated potential complications. […] In the type of vascular ring described (i.e., RAA with aberrant LSA and LLA), the two primary factors causing tracheoesophageal compression are the space-occupying effect of the KD and the sling-like effect of the aberrant LSA. Therefore, to relieve the compression, the surgical repair should aim to divide the arterial ligament, obliterate the KD, as it can be an indication for reoperation, and transfer the LSA to the LCA. […] The surgical repair of vascular rings has a very low risk of morbidity and mortality, with favorable mid- and long-term outcomes. The obliteration of the KD and reimplantation of the LSA achieve good outcomes in eliminating respiratory and esophageal symptoms after the vascular ring repair. […] This case underscores the significance of managing symptomatic vascular rings via early surgical repair and introduces an alternative method for the objective intraoperative assessment of esophageal compression relief in patients with vascular rings.

    Vascular rings involve an abnormal development of aortic arch and branches during embryological development in neonatal period which causes compression on trachea and/or esophagus; resulting in symptoms such as cough, recurrent respiratory infections, wheezing, dysphagia or respiratory distress. […] Once the patient was diagnosed, surgical treatment is required for decompression as a standard therapy. Despite surgical techniques often differ depending on the anatomical features of the disease, several reports indicate satisfactory results with low mortality and event-free long-term outcomes. […] Vascular rings are classified under six main subgroups, which are: double aortic arch occurring due to the persistence of the fourth right aortic arch, right-sided aortic arch + aberrant left subclavian artery developing as a result of persistence of the aortic arch and regression of the fourth left arch between left subclavian artery and the left carotid artery and left aortic arch + aberrant right subclavian artery (ARSA) occurs following regression of the fourth right arch between the carotid and subclavian arteries. […] The goal of the surgery is to relieve the compression over tracheal and/or esophagus by dividing the dislocated vessel while providing sufficient blood flow towards the head. The outcomes after the surgery are satisfactory and lead to uneventful long-term survival.

    All congenital vascular anomalies that cause compression of the trachea and/or esophagus. […] Severity of symptoms and time of presentation are directly proportional to the tightness of the ring. […] The diverticulum is an important factor in causing compressive symptoms. If there is no diverticulum there is possibly a different etiology for breathing or swallowing issues. […] There are many in cardiothoracic literature who do not see this as a compressive entity and are reluctant to operate and treat an aberrant right subclavian artery. […] The decision for surgery is a joint decision between multiple actors. It will often not be clear that dysphagia or airway difficulty are a direct result of vascular compression. Ultimately, cardiothoracic surgery is responsible to the decision to proceed with treatment but it often involves discussions with pulmonology, cardiology, otolaryngology and the family. […] Surgical outcomes are generally very good (70-90% resolution). Dysphagia almost always resolves and persistent problems after initial repair are often related to tracheal anomalies.
