Current Understanding and Gaps in Research of Carotid Webs in Ischemic Strokes

The limited clinical data on CaWs, although complicated by selection bias, suggest an increased prevalence of these vascular entities in cerebral ischemic events among patients younger than 60 years. Imaging suggests CaW to be a possible nidus for cerebral thromboembolism. Physicians should consider CaW as a cause of stroke in younger patients with anterior circulation ischemic strokes of an otherwise undetermined cause. Treatment options in CaWs with ischemic strokes have not been extensively investigated. Multicenter observational studies evaluating the natural history of CaW are warranted.
