All interventions for carotid revascularization (carotid endarterectomy, carotid stenting, and transcarotid artery revascularization) carry some risk of stroke; however, where the risk of stroke over time from medical management alone is high, intervention may be beneficial. Carotid artery stenting and carotid endarterectomy have been found to ...
Carotid artery dissection is a serious condition in which a tear forms in one of the two main carotid arteries in the neck, allowing blood to enter the artery wall and separate its layers (*dissection*). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially ...
A blood clot that reaches your brain can cause a stroke. Symptoms of a stroke include sudden: ... A carotid endarterectomy is a minimally invasive procedure to remove plaque from within your ...
The symptoms of brain ischemia reflect the anatomical region undergoing blood and oxygen deprivation. Ischemia within the arteries branching from the internal carotid artery may result in symptoms such as blindness in one eye, weakness in one arm or leg, or weakness in one entire side of the body.
That sound can signal carotid artery stenosis—narrowing of the blood vessels that carry blood from the heart to the brain—or the rare vascular disease fibromuscular dysplasia.
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .

The TOAST (Trial of Org 10172 in Acute Stroke Treatment) classification is based on clinical symptoms as well as results of further investigations; on this basis, a stroke is classified as being due to (1) thrombosis or embolism due to atherosclerosis of a large artery, (2) embolism of cardiac origin, (3) occlusion of a small blood vessel, (4 ...
Screening for carotid artery narrowing has not been shown to be a useful test in the general population. [143] Studies of surgical intervention for carotid artery stenosis without symptoms have shown only a small decrease in the risk of stroke. [144] [145] To be beneficial, the complication rate of the surgery should be kept below 4%. Even then ...
