Carotid Web as a Rare Cause of Stroke: A Case Report.

A carotid web is a rare, focal vascular malformation at the posterior wall of the carotid bulb, which can be associated with acute ischemic stroke, especially in young patients. Also, a carotid web is associated with a high risk of stroke recurrence, despite optimal antithrombotic therapy. Our patient is a 41-year-old, previously healthy female, with a symptomatic carotid web on the right carotid artery, which led to acute embolic ischemic lesions in the right insular and frontal juxtacortical regions. She had recurrent episodes of mild left-sided hemiparesis and dysarthria, with complete spontaneous recovery. Extensive diagnostic procedures did not confirm any other cause of stroke except a symptomatic carotid web. She underwent stent placement, with no new vascular events, a normal neurological examination, and maintaining stent patency 1 year after the stroke onset. A carotid web is an important cause of stroke in young patients, potentially preventable by endovascular stent placement, alongside the best medical treatment.
