Overview

Carotid web is considered to be a less common, but overlooked cause of recurrent cryptogenic ischemic stroke. It is defined as a fibromuscular dysplasia forming a shelf-like protrusion in the carotid bulb that alters regional hemodynamics with a high risk of blood clot formation and its embolization intracranially. The web could be well visualized on CTA; however, it can be missed in the absence of significant carotid stenosis or the presence of an intraluminal thrombus. Treatment includes antiplatelet therapy, but also interventions – carotid endarterectomy or endovascular stenting. The carotid web typically leads to ischemic stroke in younger patients without any other cardiovascular risk factors.

Keywords:
