Background and Purpose Despite the widespread adoption of mechanical thrombectomy (MT) for the treatment of large vessel occlusion stroke (LVOS) in the anterior circulation, the optimal strategy for the treatment tandem occlusion related to cervical internal carotid artery (ICA) dissection is still debated. This individual patient pooled analysis investigated the safety and efficacy of prior intravenous thrombolysis (IVT) in anterior circulation tandem occlusion related to cervical ICA dissection treated with MT. Methods We performed a retrospective analysis of two merged prospective multicenter international real-world observational registries: Endovascular Treatment in Ischemic Stroke (ETIS) and Thrombectomy In TANdem occlusions (TITAN) registries. Data from MT performed in the treatment of tandem LVOS related to cervical ICA dissection between January 2012 and December 2019 at 24 comprehensive stroke centers were analyzed. The primary endpoint was a favorable outcome defined as 90-day modified Rankin Scale (mRS) score of 0–2. Results The study included 144 patients with tandem occlusion LVOS due to cervical ICA dissection, of whom 94 (65.3%) received IVT before MT. Prior IVT was significantly associated with a better clinical outcome considering the mRS shift analysis (common odds ratio, 2.59; 95% confidence interval [CI], 1.35 to 4.93; P=0.004 for a 1-point improvement) and excellent outcome (90-day mRS 0–1) (adjusted odds ratio [aOR], 4.23; 95% CI, 1.60 to 11.18). IVT was also associated with a higher rate of intracranial successful reperfusion (83.0% vs. 64.0%; aOR, 2.70; 95% CI, 1.21 to 6.03) and a lower rate of symptomatic intracranial hemorrhage (4.3% vs. 14.8%; aOR, 0.21; 95% CI, 0.05 to 0.80). Conclusions Prior IVT before MT for the treatment of tandem occlusion related to cervical ICA dissection was safe and associated with an improved 90-day functional outcome.

Background and Purpose 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 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 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 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.
