Choroba tętnic szyjnych
Objawy

Choroba tętnic szyjnych, będąca najczęściej wynikiem miażdżycy, prowadzi do zwężenia lub całkowitej okluzji tętnic szyjnych, co ogranicza przepływ krwi bogatej w tlen do mózgu. Proces ten przebiega często bezobjawowo, aż do momentu poważnego zwężenia (70-99%), które znacząco zwiększa ryzyko udaru niedokrwiennego. Objawy kliniczne obejmują przejściowe ataki niedokrwienne (TIA) oraz udary, manifestujące się nagłym osłabieniem jednostronnym, zaburzeniami mowy, widzenia, równowagi czy silnym bólem głowy. Amaurosis fugax, czyli przejściowa ślepota jednooczna trwająca do godziny, jest charakterystycznym objawem wskazującym na zwężenie tętnicy szyjnej po stronie objawów. Ryzyko udaru u pacjentów z objawową chorobą tętnic szyjnych może sięgać nawet 10% w ciągu tygodnia, podczas gdy u pacjentów bezobjawowych z >70% zwężeniem wynosi około 2,5% rocznie. Wskaźnik udaru bez leczenia wynosi 13% rocznie u osób objawowych i 2,2% u bezobjawowych, a interwencja chirurgiczna może zmniejszyć to ryzyko do 5-6% rocznie.

Choroba tętnic szyjnych – objawy i progresja

Choroba tętnic szyjnych (carotid artery disease) to stan, w którym tętnice szyjne w szyi, odpowiedzialne za dostarczanie krwi bogatej w tlen do mózgu i głowy, ulegają zwężeniu lub zablokowaniu, najczęściej w wyniku miażdżycy. Jest to proces gromadzenia się złogów tłuszczowych, cholesterolu, wapnia i innych substancji we krwi, tworzących blaszkę miażdżycową, która ogranicza przepływ krwi.12

Brak wczesnych objawów

Choroba tętnic szyjnych często rozwija się powoli i we wczesnych stadiach zwykle nie daje żadnych objawów. Większość pacjentów nie odczuwa żadnych wyraźnych symptomów, dopóki zwężenie tętnicy nie stanie się poważne.34 Choroba może pozostać niewykryta, aż do momentu, gdy stanie się na tyle zaawansowana, że znacząco ograniczy dopływ krwi do mózgu.5

W niektórych przypadkach lekarz może wykryć chorobę tętnic szyjnych podczas rutynowego badania, słysząc charakterystyczny szmer naczyniowy (tzw. bruit) podczas osłuchiwania tętnic szyjnych stetoskopem. Ten szmer powstaje w wyniku turbulentnego przepływu krwi przez zwężoną tętnicę.67

Pierwsze objawy – TIA i udar

Niestety, pierwszym objawem choroby tętnic szyjnych może być przejściowy atak niedokrwienny (TIA, transient ischemic attack) lub udar mózgu.89 TIA, często nazywany „mini-udarem”, charakteryzuje się tymczasowym ograniczeniem dopływu krwi do mózgu i objawami podobnymi do udaru, które jednak ustępują samoistnie, zazwyczaj w ciągu kilku minut do godziny, a całkowicie w ciągu 24 godzin.1011

Przejściowy atak niedokrwienny (TIA) jest poważnym sygnałem ostrzegawczym. Osoba, która doświadczyła TIA, ma 10-krotnie większe ryzyko wystąpienia pełnoobjawowego udaru mózgu niż osoba, która nie miała TIA.1213

Objawy TIA i udaru

Objawy TIA i udaru mózgu są podobne i mogą obejmować:1415

  • Nagłe osłabienie lub drętwienie twarzy, kończyn (szczególnie po jednej stronie ciała)1617
  • Nagłe problemy z mową, trudności w mówieniu lub rozumieniu mowy18
  • Nagłe zaburzenia widzenia w jednym lub obu oczach (częściowa lub całkowita utrata wzroku, zamazane widzenie)1920
  • Nagłe zawroty głowy, utrata równowagi lub koordynacji21
  • Nagły, silny ból głowy bez znanej przyczyny22
  • Dezorientacja lub splątanie23
  • Opadnięcie jednej strony twarzy24
  • Trudności w przełykaniu25

W przypadku TIA objawy ustępują w ciągu 24 godzin, podczas gdy w przypadku udaru mogą utrzymywać się dłużej i prowadzić do trwałych uszkodzeń mózgu.2627

Mechanizmy powstawania objawów

Objawy choroby tętnic szyjnych powstają na skutek kilku mechanizmów:28

  1. Całkowite zablokowanie tętnicy (całkowita okluzja) – gdy blaszka miażdżycowa zamyka całkowicie światło tętnicy
  2. Zakrzepica – gdy obszar blaszki miażdżycowej pęka, uszkadzając wyściółkę tętnicy
  3. Zatorowość – najważniejszy mechanizm, odpowiedzialny za większość udarów, gdy fragment skrzepliny utworzonej na blaszce odrywając się, przemieszcza się z krwią do mózgu, gdzie blokuje naczynia mózgowe2930

Lokalizacja objawów zależy od tego, które naczynia krwionośne w mózgu zostały zablokowane. Każda część mózgu kontroluje określone funkcje ciała. Na przykład, gdy zablokowana zostaje tętnica zaopatrująca oko, mogą wystąpić zaburzenia widzenia.31

Rzadsze objawy

Poza typowymi objawami TIA i udaru, choroba tętnic szyjnych może powodować również inne, rzadziej występujące symptomy:32

  • Drżenie kończyn
  • Chromanie siatkówki (przejściowe zaburzenia widzenia wskutek niedokrwienia)
  • Ból głowy spowodowany powiększonymi tętnicami szyjnymi zewnętrznymi, tworzącymi krążenie oboczne
  • Omdlenia
  • Ogólne zmęczenie
  • Zaburzenia pamięci i funkcji poznawczych33
  • Dzwonienie w uszach34

Amaurosis fugax

Amaurosis fugax (przejściowa ślepota jednooczna) to specyficzny objaw choroby tętnic szyjnych, charakteryzujący się nagłą, przejściową utratą wzroku w jednym oku, często opisywaną jako „kurtyna zapadająca na oko”. Jest to częsty objaw zwężenia tętnicy szyjnej po tej samej stronie, powodującego zatory do tętnicy ocznej lub siatkówkowej.3536

Ten objaw może trwać od kilku minut do godziny i jest poważnym sygnałem ostrzegawczym, że pacjent może wkrótce doświadczyć zablokowania tętnicy szyjnej. Należy natychmiast skontaktować się z lekarzem.37

Progresja choroby tętnic szyjnych

Naturalny przebieg choroby

Choroba tętnic szyjnych zazwyczaj rozwija się powoli. W większości przypadków progresja choroby trwa kilka lat. Badania wskazują, że średni czas progresji wynosi 8-10 lat u osób bez objawów. Jednak u osób z chorobami współistniejącymi tempo progresji może być stosunkowo szybsze.3839

Progresja choroby może przyspieszyć, szczególnie u osób z istniejącymi schorzeniami lub czynnikami ryzyka związanymi ze stylem życia. Ta szybka progresja może skutkować nagłymi, poważnymi objawami lub powikłaniami, co czyni wczesne rozpoznanie i leczenie choroby niezwykle istotnym.40

W badaniu nad naturalnym przebiegiem progresji zwężenia tętnicy szyjnej wewnętrznej, wśród 467 pacjentów, 5,6% (26 osób) rozwinęło objawy. Z tej grupy 38,5% (10 osób) doświadczyło udarów niedokrwiennych, 26,9% (7 osób) miało przemijające ataki niedokrwienne w półkuli mózgowej, 11,5% (3 osoby) doświadczyły amaurosis fugax, a 23,1% (6 osób) miało inne objawy. Badanie to potwierdziło, że znaczna liczba pacjentów ze zwężeniem tętnic szyjnych doświadcza progresji choroby.41

Stopnie zwężenia i ryzyko udaru

Stopień zwężenia tętnicy szyjnej ma bezpośredni wpływ na ryzyko wystąpienia udaru:42

  • Łagodne do umiarkowanego zwężenie (15-49%): We wczesnych stadiach pacjent może mieć tylko łagodną chorobę tętnic szyjnych. Z czasem, zwężenie to może postępować i prowadzić do udaru.43
  • Umiarkowane zwężenie (50-69%): Przy zwężeniu przekraczającym 50%, pacjenci mogą zacząć odczuwać objawy. Osoby z objawami i zwężeniem w tym zakresie mogą odnieść korzyści z leczenia operacyjnego.44
  • Znaczne zwężenie (70-99%): Przy znacznym zwężeniu ryzyko udaru znacząco wzrasta. Osoby z ciężkim zwężeniem (70% do 99%) odnoszą największe korzyści z zabiegów udrażniających tętnice.45
  • Prawie całkowite zwężenie (>80%): Tętnica szyjna jest zwykle uważana za prawie całkowicie zablokowaną, gdy zwężenie przekracza 80%. W takim przypadku pacjent jest narażony na wysokie ryzyko przejściowego ataku niedokrwiennego (TIA) lub udaru.4647

Ryzyko udaru w zależności od stanu pacjenta

Ryzyko wystąpienia udaru różni się znacząco w zależności od tego, czy pacjent miał już wcześniej objawy choroby tętnic szyjnych:48

  • Pacjenci bezobjawowi: Jeśli pacjent nie miał wcześniej żadnych problemów, ale jego tętnica jest zwężona o ponad 70%, ryzyko udaru wynosi około 2,5% rocznie (około 10-20% w ciągu 5 lat).4950
  • Pacjenci objawowi: Jeśli pacjent miał niedawno TIA lub udar z istotnie zwężoną tętnicą, ryzyko wystąpienia kolejnego – potencjalnie poważniejszego – udaru może wynosić nawet 10% w ciągu następnego tygodnia.51

Bez leczenia, choroba tętnic szyjnych ma wskaźnik udaru wynoszący 13% rocznie u osób z objawami i 2,2% rocznie u osób bez objawów.52 Operacja może zmniejszyć to ryzyko do 5-6% w tym samym okresie.53

Potencjalne powikłania

Nieleczona choroba tętnic szyjnych może prowadzić do poważnych powikłań, w tym:5455

  • Udar niedokrwienny – najczęstsze i najpoważniejsze powikłanie, spowodowane brakiem dopływu krwi do części mózgu
  • Trwałe uszkodzenie mózgu – komórki mózgowe zaczynają obumierać już po kilku minutach bez tlenu
  • Niepełnosprawność – w tym osłabienie lub paraliż jednej strony ciała, problemy z mową lub widzeniem
  • Problemy poznawcze – trudności z myśleniem, rozumowaniem i pamięcią
  • Zgon – udar jest piątą wiodącą przyczyną śmierci w Stanach Zjednoczonych56

Udar spowodowany zablokowaniem tętnicy szyjnej pozostaje jednym z najbardziej niszczycielskich skutków choroby tętnic szyjnych, często prowadzącym do poważnych długoterminowych konsekwencji.57

Czynniki wpływające na progresję choroby

Standardowe czynniki ryzyka miażdżycy wieńcowej i ogólnoustrojowej dotyczą również zwężenia tętnicy szyjnej:58

  • Podeszły wiek
  • Płeć męska
  • Historia rodzinna
  • Palenie tytoniu
  • Nadciśnienie tętnicze
  • Hiperlipidemia
  • Siedzący tryb życia
  • Wysoka zawartość tłuszczu w diecie
  • Cukrzyca
  • Otyłość
  • Uraz szyi59

Możliwość spowolnienia progresji

Chociaż złogi miażdżycowe można usunąć jedynie poprzez zabieg chirurgiczny, zmiany stylu życia mogą zatrzymać lub zapobiec progresji zwężenia tętnicy szyjnej:6061

  • Stosowanie diety korzystnej dla serca
  • Regularne ćwiczenia fizyczne
  • Zaprzestanie palenia
  • Utrata masy ciała
  • Zmniejszenie spożycia soli
  • Kontrola przewlekłych stanów, takich jak cukrzyca i wysokie ciśnienie krwi6263

W przypadku łagodnego do umiarkowanego zwężenia tętnicy szyjnej, modyfikacje stylu życia i leki, takie jak aspiryna i leki obniżające poziom cholesterolu, mogą zapobiec progresji choroby. Leczenie może wymagać korekty w miarę postępu choroby.6465

Znaczenie wczesnego wykrycia

Wczesne wykrycie choroby tętnic szyjnych jest kluczowe dla zapobiegania udarowi. Ponieważ choroba często nie daje wczesnych objawów, regularne badania lekarskie są bardzo ważne, szczególnie dla osób z czynnikami ryzyka.6667

W przypadku osób z czynnikami ryzyka, lekarz może wykryć chorobę słuchając szmerów naczyniowych nad tętnicami szyjnymi podczas rutynowego badania. Jeśli usłyszy szmer (bruit), mogą być konieczne dalsze badania.68

Wczesne rozpoznanie i odpowiednie leczenie choroby tętnic szyjnych może znacznie poprawić rokowanie i jakość życia pacjenta. Jeśli istnieje ryzyko rozwoju choroby ze względu na historię medyczną, styl życia lub genetykę, ważne jest, aby znać jej objawy i niezwłocznie skonsultować się z lekarzem.69

Znaczenie natychmiastowej pomocy medycznej

W przypadku wystąpienia jakichkolwiek objawów udaru lub TIA, należy natychmiast szukać pomocy medycznej. Każde opóźnienie w leczeniu może prowadzić do nieodwracalnego uszkodzenia mózgu.70

Jeśli przepływ krwi jest zakłócony przez więcej niż 3 do 6 godzin od udaru, uszkodzenie jest zwykle trwałe. Dlatego też, szybka reakcja medyczna jest kluczowa.71

Dotyczy to również objawów TIA, nawet jeśli ustępują one samoistnie. TIA jest poważnym sygnałem ostrzegawczym o progresji choroby tętnic szyjnych i wskazuje na wysokie ryzyko przyszłych udarów.72

Nawet jeśli objawy trwają tylko kilka sekund, ważne jest, aby jak najszybciej szukać pomocy medycznej, ponieważ te oznaki mogą wskazywać na zwiększone ryzyko udaru.73

    https://medlineplus.gov/carotidarterydisease.html
    Your carotid arteries are two large blood vessels in your neck. They supply your brain and head with blood. If you have carotid artery disease, the arteries become narrow or blocked, usually because of atherosclerosis. Atherosclerosis is the buildup of plaque, which is made up of fat, cholesterol, calcium, and other substances found in the blood. […] Carotid artery disease often does not cause symptoms until the blockage or narrowing is severe. One sign may be a bruit (whooshing sound) that your doctor hears when listening to your artery with a stethoscope. Another sign is a transient ischemic attack (TIA), a „mini-stroke.” A TIA is like a stroke, but it only lasts a few minutes, and the symptoms usually go away within an hour. Stroke is another sign.
  • #2 Carotid Artery Disease: Causes, Risk Factors, and Treatment
    https://www.healthline.com/health/carotid-artery-disease
    Early carotid artery disease rarely causes symptoms. Symptoms are only likely to appear once one of your carotid arteries has become fully blocked or nearly blocked. A carotid artery is usually considered nearly blocked when its more than 80 percent blocked. […] At that point, you’re at high risk for a transient ischemic attack (TIA) or a stroke. A TIA is also known as a ministroke because it causes stroke symptoms that last from a few minutes to a few hours. These symptoms include: sudden weakness or numbness in the face, arms, or legs (usually on one side of the body), trouble speaking (garbled speech) or understanding, sudden vision problems in one or both eyes, dizziness, sudden, severe headache, drooping on one side of your face. […] Call 911 or go to the emergency room immediately if you experience any of these symptoms. They could be signs of a medical emergency.

    https://www.bhf.org.uk/informationsupport/heart-matters-magazine/medical/stroke-and-carotid-artery-disease
    Carotid artery disease is a common cause of stroke. […] Carotid artery disease is the name given to narrowing (stenosis) of one or both of the carotid arteries, located at the front of your neck. […] The underlying cause of carotid artery disease is usually atherosclerosis (the build-up of fibrous and fatty material inside the arteries), in this case in the carotids. Over time, this material forms a plaque. This builds gradually over the years, resulting in a bigger plaque and the progressive narrowing of the arteries. As arteries narrow, this can restrict blood flow. […] Carotid artery disease is a major cause of stroke, accounting for about 20 in 100 of all cases. […] Its possible to have carotid artery disease and no symptoms. Usually, it is diagnosed after someone has a stroke or a transient ischaemic attack (TIA) sometimes called a mini-stroke. The symptoms of stroke and TIA are identical and can include weakness in your face or arms and speech problems.
  • #11 Carotid Artery Disease | BIDMC of Boston
    https://www.bidmc.org/conditions-and-treatments/heart-and-vascular/carotid-artery-disease
    As plaque builds and the carotid arteries continue to narrow, the amount of blood the brain receives is reduced. The blockage of blood flow to the brain can result in a stroke. […] Carotid artery disease may not cause any signs or symptoms until the arteries are badly blocked. As a result, for some people, the first sign of the disease may be a stroke. […] Warning signs of a stroke include transient ischemic attack (TIA) or „mini-stroke”: Sudden weakness or numbness on one side of the face, or in one arm or leg; Inability to control the movement of an arm or leg; Loss of vision or blurred vision in one or both eyes; Inability to speak clearly; Dizziness or confusion.

    There are no symptoms of carotid artery disease itself. But you may have warning signs of a stroke. A transient ischemic attack (TIA or mini-stroke) is one of the most important warning signs. A TIA happens when a blood clot briefly blocks blood flow to the brain. Symptoms of a TIA and a stroke are the same, but they last only a short time (minutes to fewer than 24 hours) during a TIA. Symptoms include one or more of the following: […] A person who has had a TIA is 10 times more likely to have a major stroke than someone who has not had a TIA.
  • #13 Carotid Artery Disease | BIDMC of Boston
    https://www.bidmc.org/conditions-and-treatments/heart-and-vascular/carotid-artery-disease
    If such symptoms persist after 24 hours, you have probably suffered a stroke.

    Because plaque buildup happens gradually, carotid artery disease can have few signs in the beginning. The first symptom is usually a stroke or mini-stroke, called a transient ischemic attack (TIA). A stroke occurs when a blood clot blocks blood flowing to your brain. A TIA is similar, but the clot blocks blood flow only for a short time and may not cause permanent damage. […] If you or someone you love has any of these symptoms, call 911 right away. Remember to BE FAST: Sudden loss of balance or coordination, Sudden change in vision, like vision loss, blurry or double vision, Facial droop, uneven smile, Limb weakness or numbness, often on one side of your body, Slurred speech, trouble speaking or understanding what others are saying, Sudden onset of the worst headache of your life.

    Carotid artery disease reduces the flow of oxygen to the brain. […] The disease may have no symptoms. In some cases, the first sign of the disease is a transient ischemic attack (TIA) or stroke. […] Symptoms of a TIA or stroke may include: Sudden weakness or clumsiness of an arm or leg on one side of the body. Sudden paralysis of an arm or leg on one side of the body. Loss of coordination or movement. Confusion, loss of ability to concentrate. Dizziness, fainting, or headache. Numbness or loss of feeling in the face or in an arm or leg. Temporary loss of vision or blurred vision. Inability to speak clearly or slurred speech. […] The symptoms of a TIA and stroke are the same. A stroke is loss of blood flow (ischemia) to the brain that lasts long enough to cause brain damage. […] Recovery also depends on the size and location of the stroke. A stroke may result in long-term problems, such as weakness in an arm or leg. It may cause paralysis, loss of speech, or even death. […] The symptoms of carotid artery disease may look like other health problems. See your healthcare provider for a diagnosis.

    The symptoms that you get depend on which blood vessels are blocked and which part of the brain they supply with oxygen. […] Carotid artery disease may also be discovered during a health check if the doctor listens to your carotid arteries and hears a whooshing sound (called a carotid bruit). […] There are three main ways in which this can happen. The first is when plaque narrows and completely blocks a carotid artery (total occlusion); the second is by thrombosis, which is when an area of plaque ruptures, damaging the lining of the artery. […] The third way, which is the most significant because it is the mechanism that causes most strokes, is by an embolism where a clot that forms on the plaque breaks off and passes in the blood to the brain, where it blocks a brain blood vessel. […] Both stroke and TIA are important warning signs that the risk of another stroke is increased, particularly over the following few days and weeks. […] If these patients dont have an operation, the risk of having a stroke in a year is only about 1 per cent. This is compared with a 20 to 30 per cent risk in the first year for a person who has had symptoms such as a TIA and has a tight stenosis.

    Carotid artery disease in itself has no symptoms. It is only when blood flow to parts of the brain is decreased that the diagnosis is made. Decreased blood supply to the brain may result in either a TIA (transient ischemic attack) or stroke (CVA, or cerebrovascular accident). […] A transient ischemic attack is a stroke-like group of symptoms that resolves on its own and should be considered a warning sign a stroke is imminent. […] Symptoms of a TIA may include: Weakness and/or numbness on one side of the body, Weakness of the face on one side, Difficulty with speech, Loss of vision, Loss of balance, Confusion. […] While the symptoms of a TIA tend to resolve on their own in a few minutes, they may last up to 24 hours. […] Signs and symptoms of a stroke are similar to a TIA but the effects are permanent without successful treatment. […] The progression of carotid artery disease is typically slow as shown in most studies. The average time for progression is 8-10 years in asymptomatic people.
