Abstract:
Carotid artery webs are exceptionally rare, generally regarded as an atypical manifestation of fibromuscular dysplasia, and described as shelf-like lesions arising from the carotid bulb or proximal internal carotid artery. However, the morphological characteristics of carotid webs arising in the common carotid artery (CCA) remain poorly defined. We report an incidental diagnosis of a CCA web in a 38-year-old asymptomatic male patient who was successfully treated with carotid artery stenting. Comparison with previously reported cases revealed recurring morphologic features that differ from those of classical carotid webs. These observations raise the possibility that CCA webs represent a distinct morphological variant within the spectrum of the disease.
