Treatment of Symptomatic Carotid Webs: A Single-Center Review

Abstract

IntroductionCarotid webs are abnormal thin shelf-like or flap-like tissue in the carotid bulb (proximal internal carotid artery). Rarely are carotid webs detected prior to symptoms since routine carotid artery surveillance is not performed in younger individuals without traditional risk factors for carotid disease. The cause and natural history remain unknown. In general, they are not common, but should be considered in the differential diagnosis of a patient who presents with ischemic neurologic symptoms. The web can create a flow disturbance, potentiating local thrombus formation, which can embolize producing resulting in cerebral ischemia. Current treatment is to reduce thrombus formation (antithrombotics and/or anticoagulation) or to alter the flow disturbance caused by the web (surgical removal or stent). MethodsWe retrospectively identified all patients presenting with acute ischemic stroke to our Comprehensive Stroke Center that were diagnosed with carotid web from January 2020 to December 2023. Patient demographics, presentation, hospital course including treatment and complications were collected and reported. ResultsFifteen patients presented with carotid web and stroke from 2020-2023 and 13 underwent carotid artery stenting or endarterectomy with no periprocedural complications. Most (40%) carotid webs were not primarily identified by the initial radiology interpretation. DiscussionWe discuss our experience of carotid web and its management as well as review of the current literature.
