Przetoki tętniczo-żylne opony twardej
Leczenie

Przetoki tętniczo-żylne opony twardej (DAVF) to patologiczne połączenia między tętnicami a żyłami w oponie twardej mózgu lub rdzenia kręgowego, które wymagają indywidualnego podejścia terapeutycznego w oparciu o ich lokalizację, wzorzec drenażu żylnego oraz objawy kliniczne. Leczenie jest wskazane szczególnie w przypadku przetok wysokiego stopnia z drenażem do żył korowych, gdzie ryzyko krwotoku wewnątrzczaszkowego wynosi około 8% rocznie. Pierwszą linią terapii jest embolizacja wewnątrznaczyniowa, wykonywana przeztętniczo (TAE) lub przezżylnie (TVE), z użyciem materiałów takich jak Onyx, spirale, kleje tkankowe (np. NBCA) czy PHIL. Skuteczność embolizacji ocenia się na 66-80% całkowitej okluzji przetoki, z poprawą objawów u 80-98% pacjentów, przy powikłaniach neurologicznych w 2% przypadków. W przypadku niepełnej embolizacji zaleca się rozważenie leczenia chirurgicznego, które wykazuje skuteczność na poziomie około 98% całkowitej obliteracji, zwłaszcza w przetokach rdzeniowych (SDAVF), gdzie jest terapią pierwszego wyboru.

Leczenie przetok tętniczo-żylnych opony twardej – charakterystyka ogólna

Przetoki tętniczo-żylne opony twardej (DAVF, Dural Arteriovenous Fistulas) stanowią rzadkie, ale istotne klinicznie nieprawidłowe połączenia między tętnicami i żyłami w obrębie opony twardej mózgu lub rdzenia kręgowego. Decyzja o leczeniu przetok opiera się na ocenie objawów pacjenta, chorób współistniejących oraz ryzyka nadciśnienia wewnątrzczaszkowego lub krwotoku.1 Zmiany bezobjawowe o niskim stopniu zaawansowania są zwykle leczone zachowawczo z regularnym monitorowaniem, natomiast przetoki wysokiego stopnia z odpływem do żył korowych lub objawowe kwalifikują się do interwencji.23

Celem leczenia DAVF jest całkowite przerwanie połączenia między przetoką a jej drenażem żylnym. Niekompletne przerwanie może umożliwić rekrutację innych tętnic do przetoki i może nie poprawić ryzyka krwotoku lub objawów.4 W przypadku przetok z drenażem żylnym korowym, ryzyko krwotoku wewnątrzczaszkowego wynosi około 8% rocznie, dlatego leczenie jest zazwyczaj wskazane.5

Współczesne opcje terapeutyczne obejmują:67

Embolizacja wewnątrznaczyniowa

Embolizacja wewnątrznaczyniowa jest obecnie uważana za pierwszą linię leczenia dla większości przetok tętniczo-żylnych opony twardej.89 Ta minimalnie inwazyjna procedura polega na wprowadzeniu cewnika przez tętnicę (najczęściej w pachwinie) do miejsca przetoki pod kontrolą obrazowania rentgenowskiego. Następnie wprowadza się materiał embolizacyjny, który blokuje nieprawidłowe połączenie.1011

Techniki embolizacji

Wyróżnia się dwa główne podejścia do embolizacji:1213

1. Embolizacja przeztętnicza (TAE, Transarterial Embolization) – preferowana w przypadku przetok wysokiego stopnia z bezpośrednim drenażem do żył korowych lub gdy dostęp przezżylny jest ograniczony.14 Mikrocewniki są wprowadzane do tętnic odżywczych, z celem dotarcia jak najbliżej połączenia przetoki.15 Procedura zwykle wykonywana jest w znieczuleniu ogólnym.16

2. Embolizacja przezżylna (TVE, Transvenous Embolization) – preferowana, gdy przetoka jest zaopatrywana przez małe, kręte tętnice uniemożliwiające bezpieczny dostęp przeztętniczy do części przetokowej.17 Jest także metodą z wyboru dla przetok zatoki jamistej.1819

Materiały embolizacyjne

Do najczęściej stosowanych materiałów embolizacyjnych należą:202122

  • Onyx (kopolimer etylenu i alkoholu winylowego) – obecnie najpopularniejszy materiał, który zapewnił znaczący postęp w leczeniu wewnątrznaczyniowym DAVF. Jego zaletami są łatwiejsza kontrola podczas wstrzykiwania, możliwość podania większej objętości przez dłuższy czas oraz możliwość dotarcia do przetoki przez pojedyncze naczynie doprowadzające.2324
  • Spirale (coils) – metalowe spirale umieszczane w świetle naczynia
  • Kleje tkankowe (np. n-butylocyjanoakrylat, NBCA)
  • PHIL (Precipitating Hydrophobic Injectable Liquid) – nowszy materiał embolizacyjny25

Wprowadzenie Onyxu znacząco poprawiło skuteczność embolizacji przeztętniczej, która stała się bardziej efektywną opcją i obecnie stanowi metodę pierwszego wyboru dla wielu przetok tętniczo-żylnych opony twardej z bezpośrednim drenażem do żył korowych.2627

Skuteczność i powikłania embolizacji

Skuteczność embolizacji wewnątrznaczyniowej w leczeniu DAVF jest wysoka. Całkowitą okluzję przetoki można osiągnąć w około 66-80% przypadków.2829 Wskaźnik poprawy lub ustąpienia objawów, takich jak szum pulsacyjny czy objawy oczne, wynosi około 80-98%.303132

Powikłania związane z embolizacją wewnątrznaczyniową występują u około 8-21% pacjentów, ale trwałe deficyty neurologiczne są rzadkie (około 2%).3334 Do możliwych powikłań należą:35

  • Nadciśnienie
  • Krwotok
  • Ogniskowe deficyty neurologiczne
  • Żylaki żył oponowych

Całkowita embolizacja jest konieczna do osiągnięcia trwałych efektów leczniczych. Częściowa embolizacja może prowadzić do zmniejszenia przepływu i nadciśnienia żylnego, ale ryzyko ponownego krwawienia pozostaje niezmienione.36 W przypadku niekompletnej okluzji podczas początkowej próby embolizacji, zaleca się rozważenie leczenia chirurgicznego zamiast powtórnej embolizacji lub podejścia wyczekującego.37

Leczenie chirurgiczne

Leczenie chirurgiczne jest wskazane w przypadkach, gdy embolizacja wewnątrznaczyniowa nie powiodła się lub nie może być przeprowadzona.3839 Jest również preferowane w przypadku przetok obejmujących dno przedniego dołu czaszki.40

Techniki chirurgiczne

Techniki chirurgicznego leczenia DAVF obejmują:414243

  • Chirurgiczne przerwanie połączenia przetoki z układem żył korowych
  • Szkieletyzację zatoki opony twardej z przerwaniem dopływu tętniczego
  • Upakowanie zatoki
  • Resekcję zajętej opony twardej
  • Mikrochirurgiczne wycięcie nieprawidłowych naczyń

W przypadku rdzeniowych przetok tętniczo-żylnych opony twardej (SDAVF), typowa procedura chirurgiczna obejmuje ograniczoną hemilaminektomię po stronie żyły drenującej, wycięcie lub klipsowanie przetoki, bez usuwania żył, oraz śródoperacyjną kontrolę dopplerowską w celu potwierdzenia eliminacji patologicznego połączenia tętniczo-żylnego.44

Skuteczność i powikłania leczenia chirurgicznego

Leczenie chirurgiczne wykazuje wysoki wskaźnik powodzenia, z całkowitą obliteracją przetoki w około 98% przypadków.4546 Wskaźnik chorobowości wynosi około 2%, bez związanej z procedurą śmiertelności.47

Na podstawie niedawnych wieloośrodkowych badań kohortowych stwierdzono, że leczenie chirurgiczne jest lepsze od leczenia wewnątrznaczyniowego w zakresie całkowitej obliteracji rdzeniowych przetok tętniczo-żylnych opony twardej.48 Według Steinmetza i współpracowników, leczenie chirurgiczne powinno być terapią pierwszego rzutu w przypadku SDAVF.49

W jednym z badań wszyscy pacjenci poddani leczeniu mikrochirurgicznemu osiągnęli korzystne wyniki – albo długoterminową poprawę, albo stabilizację objawów przedoperacyjnych.50 Pacjenci z typu I SDAVF wymagają natychmiastowego leczenia ze względu na postępujący charakter choroby.51

Radiochirurgia stereotaktyczna

Radiochirurgia stereotaktyczna (SRS) wykorzystuje precyzyjnie ukierunkowane promieniowanie do blokowania nieprawidłowego połączenia w naczyniach krwionośnych.52 Jest zazwyczaj stosowana w przypadkach przetok niskiego stopnia (Borden typ I) z uporczywymi objawami, takimi jak pulsujący szum uszny, lub w przypadkach o niekorzystnej anatomii dla innych interwencji, u pacjentów ze znaczącymi chorobami współistniejącymi, lub jako terapia ratunkowa dla zmian niekompletnie leczonych chirurgicznie lub embolizacją wewnątrznaczyniową.53

Technika i dawkowanie

Podczas zabiegu obszar przetoki napromieniany jest dawką 20-30 Gy, co powoduje zakrzepicę naczyń i zamknięcie przetoki.54 Do radiochirurgii stereotaktycznej można wykorzystać różne technologie, w tym akcelerator liniowy (LINAC), Gamma Knife i terapię protonową.55

Skuteczność i ograniczenia radiochirurgii

Radiochirurgia stereotaktyczna osiąga doskonałe wskaźniki obliteracji dla zmian niskiego stopnia, ale jest mniej skuteczna w przypadku zmian wyższego stopnia.56 Efekt końcowy może pojawić się dopiero po kilku miesiącach do kilku lat, a ryzyko krwotoku utrzymuje się do czasu ostatecznej obliteracji.57

SRS jest rzadziej stosowana w leczeniu przetok tętniczo-żylnych opony twardej i zazwyczaj zarezerwowana jest jako ostatnia opcja ratunkowa.58 W przypadku przetok rdzeniowych, zastosowanie radiochirurgii stereotaktycznej jest bardzo ograniczone, a doniesienia dotyczące jej użycia w tych przypadkach są nieliczne.59

Leczenie skojarzone

W niektórych przypadkach stosuje się podejście wielomodalne, łączące różne metody leczenia.6061 Połączenie embolizacji wewnątrznaczyniowej z leczeniem chirurgicznym może zapewnić obliterację w około 90% przypadków DAVF przy niskim ryzyku powikłań związanych z procedurą.62

Często stosowane schematy leczenia skojarzonego obejmują:6364

  • Embolizację przed zabiegiem chirurgicznym w celu zmniejszenia przepływu krwi przez przetokę
  • Leczenie chirurgiczne po nieudanej embolizacji
  • Radiochirurgię stereotaktyczną jako uzupełnienie po niekompletnej embolizacji lub leczeniu chirurgicznym

W przypadkach rozległych naczyń kolateralnych lub naczyń doprowadzających, pierwszą opcją jest leczenie chirurgiczne. Zaleca się również leczenie chirurgiczne jako ostateczne leczenie DAVF w nawracających przetokach z kolateralizacją z przeciwnej strony lub innych poziomów.65

Wybór metody leczenia

Wybór optymalnej metody leczenia zależy od wielu czynników, w tym:6667

  • Anatomii przetoki
  • Wzorca drenażu żylnego
  • Obecności lub braku drenażu żylnego korowego
  • Lokalizacji przetoki
  • Objawów klinicznych
  • Ogólnego stanu zdrowia pacjenta
  • Ryzyka krwawienia lub powikłań

Wskazania do leczenia

Wskazania do leczenia przetok tętniczo-żylnych opony twardej obejmują:6869

  • Krwotok
  • Dysfunkcja neurologiczna
  • Oporne na leczenie objawy (np. pulsujący szum uszny)
  • Obecność drenażu żylnego korowego (ze względu na wysokie ryzyko krwotoku)

Niezależnie od objawów, przetoki z odpływem żylnym korowym powinny być leczone jak najszybciej za pomocą embolizacji wewnątrznaczyniowej lub operacji chirurgicznej ze względu na wysokie ryzyko krwotoku mózgowego.70

W przypadku przetok bezobjawowych o niskim stopniu zaawansowania, lekarz może nie zalecać natychmiastowego leczenia, a jedynie regularne monitorowanie w celu zapobiegania powikłaniom.71 Jeśli jednak pacjent nie toleruje objawów, takich jak pulsujący szum, rozważa się embolizację wewnątrznaczyniową.72

Zalecane podejście do leczenia

Na podstawie aktualnych danych zaleca się następujące podejście do leczenia DAVF:7374

  • Leczenie wewnątrznaczyniowe jako pierwsza metoda w typach I, II oraz w niekrwotocznych typach III/IV DAVF
  • Leczenie chirurgiczne jako pierwsza metoda w ostrych krwotocznych DAVF oraz jako metoda drugiego wyboru w typach III/IV DAVF nie zamkniętych skutecznie przez leczenie wewnątrznaczyniowe
  • Radiochirurgia stereotaktyczna jako alternatywa/uzupełnienie do planowego leczenia wewnątrznaczyniowego/chirurgicznego przetok czaszkowych, szczególnie typu I

W przypadku przetok rdzeniowych, po diagnostycznej angiografii kręgosłupa należy podjąć próbę embolizacji. W przeciwnym razie, leczenie chirurgiczne jest zalecanym sposobem leczenia rdzeniowych przetok opony twardej, ponieważ ma niższy wskaźnik niepowodzeń. Ze względu na postępujący naturalny przebieg z ciężkimi deficytami, zaleca się wczesne definitywne leczenie.75

Wyniki leczenia i rokowanie

Leczenie przetok tętniczo-żylnych opony twardej może usunąć przetokę i poprawić przepływ krwi w naczyniach krwionośnych. Może zmniejszyć i zapobiec nowym objawom oraz powikłaniom.76

Poprawa objawów

Po leczeniu DAVF można zaobserwować następujące efekty:7778

  • Całkowite ustąpienie pulsującego szumu usznego u około 80% pacjentów
  • Znaczna poprawa u około 11-12% pacjentów
  • Brak zmian u około 7-8% pacjentów

W przypadku rdzeniowych przetok tętniczo-żylnych opony twardej, wczesne leczenie może poprawić lub ustabilizować funkcje motoryczne i czuciowe w większości przypadków. Ból oraz dysfunkcja jelita i pęcherza ustępują tylko u mniejszości pacjentów.79

Nawroty i obserwacja długoterminowa

Nawroty przetok tętniczo-żylnych opony twardej mogą wystąpić nawet po skutecznym leczeniu, choć są stosunkowo rzadkie.8081 Czynniki ryzyka nawrotu obejmują:82

  • Lokalizację namiotową
  • Drenaż żylny korowy
  • Głęboki drenaż mózgowy

Nawrót DAVF może wystąpić pomimo początkowego wyleczenia. Może wystąpić opóźnienie w nawrocie, jeśli penetracja materiału embolizacyjnego w proksymalnej części odpływu żylnego jest niekompletna.83

Z tego powodu zaleca się regularną, długoterminową obserwację po leczeniu, w tym opóźnioną angiograficzną ocenę długoterminową (co najmniej rok od wyleczenia), szczególnie w przypadkach z czynnikami ryzyka nawrotu.8485

Specjalne przypadki kliniczne

Przetoki etmoidalne

Przetoki tętniczo-żylne opony twardej etmoidalne (eDAVF) są rzadkimi zmianami naczyniowymi mózgu, które ze względu na unikalny wzorzec drenażu żylnego korowego bez drenażu zatokowego, niosą wysokie ryzyko krwawienia mózgowego i deficytu neurologicznego.86

Dla eDAVF leczenie chirurgiczne wykazuje znacznie niższe ryzyko powikłań niż techniki wewnątrznaczyniowe, a także doskonałe wyniki w zakresie całkowitej obliteracji.87 Chirurgiczne przerwanie połączenia nadal jest najbardziej skutecznym sposobem leczenia tych przetok.88

Dla pacjentów bezobjawowych z eDAVF typu IV według klasyfikacji Cognarda, podejście podczołowe przez nadoczodołowy mini dostęp powinno być rozważone jako leczenie pierwszego rzutu w celu wyeliminowania ryzyka możliwego złośliwego przebiegu klinicznego.89

Przetoki zatoki jamistej

Leczenie wewnątrznaczyniowe stanowi terapię pierwszego rzutu dla przetok zatoki jamistej (CS-dAVF).90 Najczęstszym podejściem wewnątrznaczyniowym jest embolizacja przezżylna z użyciem spiral, która osiąga wysoki odsetek radiologicznego i klinicznego ustąpienia przetoki przy niskich wskaźnikach powikłań.91

Ogólnie, leczenie wewnątrznaczyniowe wykazało wysoki odsetek radiologicznego (79,5%) i klinicznego (85%) ustąpienia przetoki oraz niski wskaźnik powikłań (8%), z prawie nieznaczną częstością trwałego deficytu.92 Leczenie przezżylne wykazało mniej powikłań niż podejścia przeztętnicze, a okluzja spiralami wydawała się bezpieczniejsza niż stosowanie płynnych środków embolizacyjnych.93

Przetoki z objawami parkinsonizmu i demencji

Przetoka tętniczo-żylna opony twardej prezentująca się z parkinsonizmem i demencją jest rzadka i często błędnie diagnozowana.94 Główną metodą leczenia DAVF w takich przypadkach jest embolizacja wewnątrznaczyniowa.95

W opisanym przypadku, mikrocewnik został wprowadzony do przetoki tętnicy oponowej środkowej i powoli wstrzyknięto klej Onyx-18, ostatecznie osiągając embolizację. Po zabiegu objawy parkinsonizmu i demencji znacznie się zmniejszyły, a funkcje neurologiczne i wyniki w skali demencji wykazały znaczny wzrost w porównaniu z oceną przedoperacyjną.96

Po miesiącu pacjent był w stanie całkowicie sam się sobą opiekować, a po trzech miesiącach przeprowadzono leczenie stereotaktyczne dla pozostałej przetoki. Podczas rocznej obserwacji kontrolnej badanie neurologiczne wykazało, że pacjent powraca do zdrowia w sposób normalny.97

Podsumowanie i zalecenia

Leczenie przetok tętniczo-żylnych opony twardej powinno być dostosowane do indywidualnych potrzeb każdego pacjenta. Konkretne cele powinny być wyznaczone z uwzględnieniem naturalnej historii zmiany (która głównie zależy od jej wzorca drenażu żylnego), jej specyficznych cech anatomicznych oraz objawów pacjenta.98

Większość przetok opony twardej można leczyć metodami wewnątrznaczyniowymi, ale niektóre są bardziej odpowiednio leczone chirurgicznie. Niektóre trudne zmiany wymagają rozważnego połączenia technik wewnątrznaczyniowych i chirurgii.99

Zalecenia dotyczące leczenia obejmują:

  • Embolizację wewnątrznaczyniową jako pierwszą linię leczenia dla większości DAVF, z podejściem przezżylnym lub przeztętniczym w zależności od anatomii przetoki
  • Leczenie chirurgiczne w przypadkach, gdy embolizacja jest niemożliwa lub niewystarczająca
  • Radiochirurgię stereotaktyczną jako opcję dla określonych przypadków, szczególnie przetok niskiego stopnia z uporczywymi objawami
  • Podejście wielomodalne, łączące różne metody leczenia, w przypadkach złożonych przetok
  • Regularną, długoterminową obserwację po leczeniu, aby wykryć ewentualne nawroty

Wczesna diagnoza i leczenie są kluczowe dla osiągnięcia optymalnych wyników, szczególnie w przypadku przetok wysokiego stopnia z drenażem żylnym korowym, które niosą znaczące ryzyko krwotoku wewnątrzczaszkowego. Leczenie przeprowadzone w ciągu pięciu dni od krwotoku związanego z DAVF wiąże się z niskim wskaźnikiem wczesnego ponownego krwawienia i wydaje się być odpowiednim przedziałem czasowym.100

    The decision of whether to treat dAVFs is based on the patient’s symptoms, medical comorbidities, and risk of intracranial hypertension or hemorrhage. Lesions that are asymptomatic and low-grade tend to have a benign natural history and are generally managed conservatively with serial monitoring.[10] […] Those that are high-grade with cortical venous drainage or symptomatic are candidates for an intervention. Open surgery, endovascular embolization, and stereotactic radiosurgery are the main options for intervention. The goal of treatment is to achieve a complete disconnection of the fistula from its venous drainage. Incomplete disconnection may allow for the recruitment of other arteries to the fistula and may not improve the risk of hemorrhage or symptoms.[12] […] Surgical treatment involves the surgical disconnection of the fistula from the cortical venous system. Occasionally, skeletonization of the dural sinus with disconnection of the dural arterial supply, packing of the sinus, or resection of the involved dura is performed.

    Dural arteriovenous fistulas (dAVF) are a heterogeneous collection of conditions that share arteriovenous shunts from dural vessels. They present variably with hemorrhage or venous hypertension and can be challenging to treat. […] Treatment largely depends on the classification of the fistula and the age and comorbidities of the patient, as well as the presence of symptoms directly attributable to the fistula. […] Conservative (especially Borden type I and Cognard types I and IIa) […] Higher grades (Borden types II and III, Cognard types IIb-V) have an annual mortality rate of ~10% and an annual risk of intracranial hemorrhage of ~8%, so treatment should be considered: endovascular, surgical resection, stereotactic radiosurgery.

    Treatment depends on the drainage pattern of the dural arteriovenous fistula and your symptoms. […] Most DAVFs can be cured with endovascular embolization, a minimally invasive procedure in which a catheter is threaded through the arteries and veins of either your wrist or leg to the site of the fistula. The fistula is then plugged with a material such as glue, a metal coil, or a balloon to correct the abnormal pattern of blood flow. […] For some DAVFs, microneurosurgery may be recommended instead of or in addition to endovascular embolization, though these cases are rare. […] Yes, the most common means of treating—and curing—a DAVF is through endovascular embolization. Open brain surgery rarely is required to treat a DAVF.

    Mayo Clinic neurosurgeons review surgical options for a dural arteriovenous fistula. […] Treatment for a dural arteriovenous fistula (dAVF) involves a procedure to block or disconnect the fistula. […] Procedures that can treat dAVF include: […] In an endovascular procedure, a long, thin tube called a catheter is inserted into a blood vessel in your leg or groin. It is threaded through blood vessels to the dural arteriovenous fistula using X-ray imaging. Coils or a glue-like substance is released to block the connection in the blood vessels. […] In stereotactic radiosurgery, precisely focused radiation blocks the irregular connection in the blood vessels. This causes blood vessels in the fistula to close off, destroying the dAVF. […] If an endovascular procedure or stereotactic radiosurgery aren’t options for you, you may need dAVF surgery. Surgery may be performed to disconnect the dAVF or cut off the blood supply and remove the fistula.

    A dural arteriovenous fistula (DAVF), also called a dural arteriovenous malformation (dural AVM), is an atypical connection between blood vessels in the dura. When necessary, surgical treatment for DAVF most commonly takes the form of endovascular embolization, microsurgical resection, or stereotactic radiosurgery. […] Dural arteriovenous fistulas are complex lesions and should be managed at major centers with specialists highly trained in their treatment. At Columbia University Irving Medical Center/NewYork-Presbyterian Hospital, our neurosurgeons are experienced in evaluating DAVFs and in treating them surgically when necessary. […] The current treatment of choice for other DAVFs is endovascular embolization. To perform this procedure, a specialist inserts a catheter through an artery in the groin and then guides the catheter through the circulatory system to the site of the DAVF. Once in position, the catheter delivers a kind of glue. The glue embolizes the abnormal passageway, blocking the abnormal connection often permanently curing the fistula.

    Dural arteriovenous fistula (DAVF) Symptoms Treatment […] Endovascular embolization is a minimally invasive procedure commonly used to treat dural arteriovenous fistulas. Its the first line of treatment in most dural AVFs. […] […] Embolization of a DAVF is performed under general anesthesia. A catheter is inserted into an artery (usually the femoral artery in the front of the hip in the thigh) to perform this treatment. The small tube-like structure or catheter is taken into the fistula location, guided by fluoroscopic or X-ray imaging. A contrast/dye is injected to help in seeing the AVFs exact location. Then an embolizing or blocking material is injected into the exact spot where the artery and vein meet to block the fistula. The most commonly used embolization material is a peculiar agent called Onyx. The AVF is cured after the connection between the artery and the vein is closed, and it rarely recurs.

    https://www.ajnr.org/content/29/2/235
    BACKGROUND AND PURPOSE: DAVFs (dural arteriovenous fistulas) represent one of the most dangerous types of intracranial AV shunts. Most of them are cured by arterial or venous embolization, but surgery/radiosurgery can be required in case of failure. Our goal was to reconsider the endovascular treatment strategy according to the new possibilities of arterial embolization using non polymerizing liquid embolic agent. […] Based on this experience, we believe that Onyx may be the treatment of choice for many patients with intracranial dural arteriovenous fistula (ICDAVF) with direct cortical venous reflux (CVR). The applicability of this new embolic agent indicates the need for reconsideration of the global treatment strategy for such fistulas. […] The present study examined the use of Onyx for endovascular treatment of ICDAVF with CVR. The study found that Onyx injections were easier to control than n-BCA injections, a much larger volume could be injected over a longer time period, injection in a single feeder allowed obtaining arterio-arterial reflux and avoided embolization of other feeders, and access through the meningeal artery was more efficient even if the size was very small.

    The goal of EVT is complete obliteration of the lesion. To achieve definite obliteration via EVT, the embolic material has to plug the arteriovenous communication or seal the lumen of the draining venous structure. […] Complete embolization is necessary. Though partial EVT can result in marked decrease in flow and venous hypertension, the risk of rebleeding remains unchanged. […] Currently, as a result of the development of new techniques and materials, particularly with the use of Onyx (Medtronic Neurovascular, Minneapolis, MN), TAE has become a more effective option and represents the first-line option for many DAVFs. […] Currently, TVE is useful for intracranial DAVFs involving the major dural sinuses. However, TVE for petroclival region DAVFs is difficult because the initial venous drainage mainly flows through the pial veins. […] In summary, EVT cannot be readily used for all petroclival region DAVFs. When the arterial feeders are large or the DAVFs are adjacent to the venous sinuses, the success rate is high.

    It appears that Onyx can be used as a primary treatment option for most cases of ICDAVF with direct CVR. This new agent provides an alternative to surgery for treatment of anterior skull base fistulas. In cases of a DAVF draining into a sinus with secondary CVR, Onyx arterial embolization may be performed as an alternative to retrograde venous catheterization. In conclusion, the technological options provided by this new embolic agent encourage a reconsideration of the global treatment strategy for DAVF with CVR.

    The treatments for TSS DAVFs included TAE, TVE and a combination of both. […] Currently, TAE is extensively used, especially after the introduction of the latest embolizing material, Onyx, which can be controllably delivered into the fistula. […] For TSS DAVFs, TVE is a more effective treatment; moreover, the combination of TAE and TVE is also useful. […] During the EVT, the SPs play an important role. After the microcatheter accesses the SPs, TSS DAVFs can be successfully treated with the selective embolization of the SPs by TAE or TVE. […] The treatment of TSS DAVFs should be based on the angioarchitecture and cortical venous reflux. […] Grade 3 TSS DAVFs can be treated with TVE, and the affected sinus and retrograde cortical drainage outlet should be tightly packed with coils.

    Initial attempt of endovascular treatment (EVT) for spinal dural arteriovenous fistula (SDAVF) is preferred because of concurrent diagnosis and treatment. […] We retrospectively reviewed 71 patients with SDAVF to evaluate treatment outcomes of SDAVF after an initial EVT attempt.

[…] Among 19 patients with incomplete occlusion upon initial EVT, 14 underwent additional surgery, 13 of whom (92.9%) obtained improved or stationary functional outcomes. […] Additional surgery achieved improved functional outcomes in cases of incomplete occlusion of SDAVF after the initial EVT attempt or recurrence rather than repeated EVT or follow-up. […] Although the surgical outcome of spinal dural arteriovenous fistula (SDAVF) is excellent, with a success rate over 95%, initial attempt of endovascular treatment (EVT) at the same session of diagnostic spinal angiography for spinal dural arteriovenous fistula (SDAVF) has become a preferred approach because of the benefit from concurrent diagnosis and treatment with a 70-90% rate of complete obliteration.

    Type I spinal dural arteriovenous fistulas (SDAVFs) are low-flow vascular shunts fed by radicular arteries in patients who most often present with myelopathy. Although some fistulas are amenable to endovascular embolization, nearly all can be treated with direct microsurgical obliteration. […] In all patients who underwent microsurgical treatment, complete angiographic obliteration of the fistula was achieved. […] Microsurgical treatment of SDAVF provides direct access to the fistula point, allowing for high obliteration rates with excellent long-term improvement of preoperative deficits and limited periprocedural complications. […] Although some groups advocate endovascular therapy, we most often employ microsurgical obliteration as the first-line treatment option, given the ability to reliably visualize and gain direct access to the fistula point.

    We prefer an operative excision, in order to exclude the collateral supply and to preserve the small radicular spinal cord feeders, which may originate close by from a common meningoradicular artery outside the dura. The unfavorable time course of the disease can be stopped and sometimes reversed with the operation. Treatment failure of embolization is still higher than that of surgery. However, embolization has the advantage of low general morbidity, and may be helpful in patients with reduced physical condition. The chance of complete cure following embolization with a permanent agent is considered to be inferior to surgery. In case of extensive collateral vessels or feeding vessels, the primary option is surgery. We also recommend surgery as the definitive treatment of dAVF in recurrent fistulas with collateralization from the opposite side or other levels.

[…] Your healthcare provider will determine the best treatment plan for you. […] Treatment can remove the fistula and improve blood flow in your blood vessels as expected. It can reduce and prevent new symptoms and complications from happening. […] The goal of dural arteriovenous fistula treatment is to remove the abnormal connection (fistula) between your artery and vein. Treatment options could include: […] Surgery: Open surgery can remove the fistula (abnormal connection) of the affected blood vessel. […] Endovascular embolization: This procedure uses a tiny tube, called a catheter, in your artery to reach the affected area and seal off the fistula.

    Considering that most dAVFs are curable with presently available treatment modalities, accurate diagnosis of dAVF presenting with only PT by performing a meticulous physical examination and choosing appropriate neuroimaging modalities is essential. […] Of the 26 patients (M:F=7:19) who were managed by endovascular embolization of the dAVF, PT disappeared completely in 21 (80.8%), was abated substantially in 3 (11.5%), and remained the same in 2 (7.7%), resulting in a subjective symptom improvement rate of 92.3%. […] No major complications occurred after endovascular treatment. […] General approaches for the management of dAVFs include conservative treatment, endovascular intervention, surgery, and radiosurgery. […] Due to the recent efficacy of endovascular therapy, microsurgical obliteration is often reserved for cases in which endovascular embolization has failed or is not feasible.

    Endovascular treatment is safe and effective for most FMR-AVF. […] Treatment was endovascular in 21/24 (87.5%), combined (endovascular+surgical) in 2/24 (8.3%), and surgical in 1/24 (4.2%). […] No AVF recurrence was seen for TA/TV, combined endovascular/surgical, or surgical groups, and there was one recurrence (7.1%) in the TV group. […] Symptomatic improvement was seen in all groups: TV (71.4% complete, 28.6% partial), TA (66.7% complete, 33.3% no follow-up), TV+TA (100% partial), endovascular/surgical (100% complete), and surgical (100% partial). […] TV embolization has a high cure rate with few complications.

    Cranial dural arteriovenous fistulas (dAVFs) are often treated with endovascular therapy, but occasionally a multimodality approach including surgery and/or radiosurgery is utilized. […] Recurrence of dAVFs after putative cure can occur after endovascular treatment. Risk factors include tentorial location, cortical venous drainage, and deep cerebral drainage. Multimodality therapy can be used to achieve cure after recurrence. A delayed long-term angiographic evaluation (at least 1 year from cure) may be warranted, especially in cases with risk factors for recurrence.

    Each of these treatments aims to restore normal blood flow, and many patients achieve a cure in that the fistula no longer affects their health or quality of life. However, close monitoring post-treatment is essential to detect any changes or complications early. […] For patients with a high risk of rupture, treatment is often prioritized to prevent life-threatening complications. […] Recovery time after dAVF treatment varies based on the chosen treatment, the fistulas location and complexity, and the individual patients health. […] Recurrence of a dAVF after successful treatment is relatively uncommon but not impossible. […] Regular follow-up appointments, often including imaging, help ensure that any recurrence is detected and managed early. […] Even after successful treatment, ongoing monitoring of a dAVF is crucial. Regular follow-up appointments help healthcare providers assess the stability of the treated dAVF and monitor for any signs of recurrence.

    In our opinion, for asymptomatic patients with eDAVF, Cognard type IV, the supraorbital keyhole subfrontal approach should be considered as the first-line treatment to eliminate the risk of possible malignant clinical course. […] We recommend early treatment for asymptomatic individuals with eDAVFs who have direct cerebral vein drainage with or without venous ectasia. This is to prevent the possibility of a malignant clinical progression. The supraorbital keyhole subfrontal technique, in combination with neuronavigation, offers a minimally invasive yet efficient approach to treat eDAVFs if patients are meticulously chosen.
