Résumé
Carotid web (CaW) is an intimal variant of fibromuscular dysplasia responsible for ipsilateral cerebral ischemic events (CIE). Symptomatic CaW likely has a high risk of recurrent CIE, but no salient prospective data are available. We aimed to assess recurrence rate and its predictors after a first-ever CIE. Consecutive Afro-Caribbean patients who had cryptogenic first-ever CIEs (ischemic stroke [IS] or transient ischemic attack [TIA]) associated with ipsilateral CaW were included in this multicenter observational cohort study. The follow-up (January 2008 to March 2019) focused on CIE recurrences. Kaplan-Meier method assessed rates of recurrences and Cox proportional hazards regression analyzed risk factors. Ninety-two patients (79 first-ever ISs and 13 TIAs; mean age±standard deviation, 49.8±9.9 years; 52 [56.5%] women) were included. During a mean follow-up of 50.5±29.6 months, 19 (20.7%) patients experienced recurrent ipsilateral CIEs (16 ISs and three TIAs). Of 23 patients receiving surgery/stenting treatment, no recurrence occurred after the intervention (median follow-up, 39.8 months [interquartile range, 27.6 to 72.4]). Under medical treatment alone, the annual recurrent CIE rate was 6.9%, and the cumulative rate was 4.4% at 30-day, 10.8% at 1-year, 19.8% at 2-year, 23.2% at 3-year, and 27.3% at 5-year. Presence of silent cerebral infarctions was the only independent risk factor of CIE recurrences (hazard ratio, 6.99; 95% confidence interval, 2.4 to 20.4; P=0.004). Under medical treatment alone, symptomatic CaW was associated with a high rate of recurrence that reached 27.3% at 5-year. Surgery/stenting seems to be efficient, and randomized control trials are required to confirm the benefit of these interventions.

BACKGROUND AND PURPOSE
OBJECTIVE
Carotid web (CaW) is an intimal variant of fibromuscular dysplasia responsible for ipsilateral cerebral ischemic events (CIE). Symptomatic CaW likely has a high risk of recurrent CIE, but no salient prospective data are available. We aimed to assess recurrence rate and its predictors after a first-ever CIE.
METHODS
METHODS
Consecutive Afro-Caribbean patients who had cryptogenic first-ever CIEs (ischemic stroke [IS] or transient ischemic attack [TIA]) associated with ipsilateral CaW were included in this multicenter observational cohort study. The follow-up (January 2008 to March 2019) focused on CIE recurrences. Kaplan-Meier method assessed rates of recurrences and Cox proportional hazards regression analyzed risk factors.
RESULTS
RESULTS
Ninety-two patients (79 first-ever ISs and 13 TIAs; mean age±standard deviation, 49.8±9.9 years; 52 [56.5%] women) were included. During a mean follow-up of 50.5±29.6 months, 19 (20.7%) patients experienced recurrent ipsilateral CIEs (16 ISs and three TIAs). Of 23 patients receiving surgery/stenting treatment, no recurrence occurred after the intervention (median follow-up, 39.8 months [interquartile range, 27.6 to 72.4]). Under medical treatment alone, the annual recurrent CIE rate was 6.9%, and the cumulative rate was 4.4% at 30-day, 10.8% at 1-year, 19.8% at 2-year, 23.2% at 3-year, and 27.3% at 5-year. Presence of silent cerebral infarctions was the only independent risk factor of CIE recurrences (hazard ratio, 6.99; 95% confidence interval, 2.4 to 20.4; P=0.004).
CONCLUSIONS
CONCLUSIONS
Under medical treatment alone, symptomatic CaW was associated with a high rate of recurrence that reached 27.3% at 5-year. Surgery/stenting seems to be efficient, and randomized control trials are required to confirm the benefit of these interventions.
