Carotid Artery Web: A rare cause of recurrent ischemic stroke

Carotid artery web is a focal form of fibromuscular dysplasia characterised by an abnormal shelf-like projection of fibrous tissue into the lumen of the carotid artery. It is a rare but important cause of recurrent ischemic stroke particularly in younger patients with few traditional risk factors. Despite that it may cause up to 37% of cryptogenic strokes, an optimal evidenced-based management strategy has not been developed. This case report provides us with the opportunity to highlight this under-recognised cause of recurrent stroke and synthesize the current evidence for its diagnosis and management.
