Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is no evidence of familial forms of carotid web. The aim of this study is to determine the prevalence of carotid web among relatives of patient with carotid web using carotid doppler ultrasound.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Carotid web are rare, focal dysplasia of the internal carotid artery and a high risk causes of stroke in young adult. Natural history of these dysplasia remains poorly understood. High prevalence of carotid web among Afro-Caribbean population and the similarity between carotid web and fibromuscular dysplasia, suggest existence of genetic factors. But there has been to our knowledge no familial form of carotid web reported. The aim of this study is to determine the prevalence of carotid web among relatives of patients with carotid web using carotid duplex doppler ultrasound.

Researchers aim to test whether carotid web could be detected in relatives of patients with known carotid web, using duplex doppler ultrasound.

This is a pilot, transversal, single-center study performed at Toulouse University Hospital, France. From 30 carotid web cases aged under 65 (patients with previously known Carotid web, symptomatic or not) followed in neurology department, investigators aim to include 60 first-degree relatives younger than 65 years old. Included relatives will underwent carotid duplex doppler ultrasound to detect carotid web. The primary outcome is the prevalence of carotid web among relatives. Secondary outcomes include : Number of families with at least one relative who has been diagnosed with carotid web, number of relatives who has been diagnosed with carotid web per family, clinical characteristics of patients and morphological characteristics of carotid web.
