Detection of Carotid Webs by CT Angiography, High‐Resolution MRI, and Ultrasound

Abstract: BACKGROUND AND PURPOSE We sought to examine carotid webs (intimal variant fibromuscular dysplasia) by studying their clinical features and imaging profiles. METHODS All patients (n = 893) of the Department of Neurology at Beijing Tiantan Hospital between January and December 2019 were retrospectively reviewed for computed tomography angiography (CTA), high‐resolution magnetic resonance imaging (HRMRI), and Doppler ultrasound data. Carotid webs were identified by two experienced neuroimaging experts according t… Show more

“…8 Doppler ultrasound combined with CTA or high-resolution magnetic resonance imaging (HRMRI) is an effective and reliable method to identify carotid webs. 9 In one of the largest case series of patients with carotid webs, the recurrent stroke risk was 30% (6 of 20 patients) in the antiplatelet therapy only group compared to 0% (0 of 7 patients) in the endarterectomy group after a mean follow-up of 2 years. 10 The most commonly reported treatments for the management of carotid webs are carotid endarterectomy and carotid artery stenting, given the prior case studies showing poor response to antiplatelet agents.…”

“…A small-sample study by Zhu et al suggested that carotid ultrasound combined with CTA and HRMRI is an effective and reliable method for diagnosing a carotid web. 11 Therefore, HRMRI could also be considered as a useful diagnostic method to detect carotid webs.…”

“…U/S was also shown to have superiority in detecting thrombus on top of the web. 9 Evidence regarding MRA for carotid web detection is very scarce, there is a case series and two case reports that investigated the MRI findings of carotid webs. In Boesen et al, 10 the carotid webs were reported retrospectively, and the detection rate was 100% of the five reported cases, with 4 of them showed thin septum protruded just proximal to the carotid bifurcation, while the position was at the level of bifurcation in one case.…”
