Symptomatic carotid web linked with stroke recurrence

First study to quantify the risk shows second strokes are five times more likely than in other patients

Patients with a symptomatic carotid web are at high risk of recurrent stroke, and medical management alone may not provide adequate protection, researchers say.

A carotid web is a shelf-like fibrous band along the posterior wall of the internal carotid artery bulb and an "under-recognised cause of young stroke", write the study authors in JAMA Neurology.

Although several studies have suggested that a carotid web raises the risk of recurrent stroke, the risk has not been quantified, they say.
