Abstract Background and aims Stroke in young adults (patients under 60 years of age) represents 10–15% of all stroke cases. Carotid web accounts for a significant portion of cryptogenic ischemic strokes in this population, ranging from 9.4% to 37%. Although CaW is a treatable etiology of stroke in the young—with multimodality imaging techniques available for diagnosis—Brazilian data remain scarce. We evaluated the presence of CaW among young stroke patients at a tertiary university hospital in Brazil. Methods This is a retrospective, observational, single-center case series study using data from a local prospective registry. Until now, data were collected from patients presenting between October 2018 and November 2025. All images were evaluated by two fellowship-trained professionals (a neuroradiologist and a neurovascular specialist) and included after a consensus read. Results Among 2,400 patients admitted with stroke, 133 were initially suspected of having a carotid web based on admission computed tomographic angiography. 83 cases were analyzed until now. Fifty-eight patients were excluded after multimodality imaging analysis and review. Of the remaining cases, 25 were CaW-related (60% female, mean age 51 years). Almost one-fifth of the patients had bilateral carotid webs. Regarding interim treatment analysis, 80% of patients received aspirin and 40% underwent angioplasty.
