Current Therapy for Carotid Webs

Abstract

Background: Carotid webs are a potential cause of ischemic stroke, particularly in younger patients with few traditional risk factors. Despite advances in imaging technology, the management of carotid webs remains poorly defined due to its rarity, absence of evidence-based guidelines, and the unique challenges presented by these lesions. This narrative review evaluates current knowledge on carotid web management, emphasizing diagnostic features, pathophysiological considerations, and treatment strategies.

Methods: A literature search was conducted using PubMed and Google Scholar databases with search terms "carotid web management," "carotid web treatment," and "carotid web," focusing on studies published between 2014 and 2024.

Results: Carotid webs are a variant of fibromuscular dysplasia and represent a potential source of embolic strokes. Despite the low overall prevalence, they account for a significant proportion of strokes in younger patients, with a high risk of recurrence when managed medically. Diagnosis often requires advanced imaging, such as computed tomography angiography or magnetic resonance angiography. Treatment options include medical management, carotid endarterectomy, and stenting, though no consensus guidelines exist. Medical management alone has a high recurrent stroke risk.

Conclusions: Carotid webs should be included in the differential diagnosis of patients with cryptogenic stroke, particularly in younger individuals. Given the high recurrence rates with medical management, both endarterectomy and stenting are recognized as safe and effective treatment options. Future prospective studies are needed to determine the optimal management strategy, including the role of preoperative anticoagulation and comparative outcomes of different treatment modalities.
