    BackgroundLittle is known regarding the endovascular management of acute ischemic stroke (AIS) related to carotid artery dissection (CAD).ObjectiveTo report our interventional experience in AIS from CAD and to compare it with conservative treatment of CAD with intravenous thrombolysis (IVT) via systematic review.MethodsRetrospective analysis of consecutive high-grade steno-occlusive CAD with National Institutes of Health Stroke Scale (NIHSS) >5 and ≤12 hours of last seen normal from 2 tertiary centers. A systematic review for studies on IVT in the setting of CAD via PubMed was performed for comparison.ResultsOf 1112 patients treated with endovascular interventions within the study period, 21 met the inclusion criteria. Mean age was 52.0 ± 10.9 years, 76% were male, NIHSS was 17.4 ± 5.8, 52% received IVT before intervention, and 90% had tandem occlusions. Mean time from last-known-normal to puncture was 4.8 ± 2.1 hours and procedure length 1.8 ± 1.0 hours. Stents were used in 52% of cases, and reperfusion (modified Treatment in Cerebral Ischemia 2b-3) achieved in 95%. No parenchymal hemorrhages were observed and 71% achieved good outcome (90-day modified Rankin Scale 0-2). The literature review identified 8 studies concerning thrombolysis in the CAD setting fitting inclusion criteria (n = 133). Our endovascular experience compared with the pooled IVT reports indicated that, despite presenting with higher NIHSS (17 vs 14; P = .04) and experiencing a longer time to definitive therapy (287 vs 162 minutes; P < .01), patients treated intra-arterially had similar rates of symptomatic cerebral/European Cooperative Acute Stroke Study-parenchymal hematoma 2 hemorrhage (0% vs 6%; P = .43) and good outcomes (71% vs 52%; P = .05).ConclusionOur study provides evidence that the endovascular management of AIS in the setting of CAD is a feasible, safe, and promising strategy.
