Overview
Embolism from atherosclerotic lesions of the carotid is the most common mechanism of stroke in patients with carotid artery disease. Thrombosis of the cerebral arteries is also a possible, less common cause of stroke.
Pathophysiology
- Atherosclerotic lesions are usually located within 2 cms of the bifurcation of the common carotid artery, most commonly o the posterior wall. These plaques can extend caudally into the common carotid artery.
- Regardless of the location, the presence of atherosclerotic plaque is a risk for developing a stroke.
- In addition to compromising the flow to the brain, the plaque can rupture and a superimposed thrombus can develop on the atheroma further exacerbating the stenosis.
