ObjectiveThe safety and efficacy of intra-arterial treatment (IAT) in patients with acute ischemic stroke (AIS) due to cervical artery dissection (CeAD) has not been formally studied. The purpose of this study was twofold: first, describe a large series with CeAD treated with IAT; second, analyze outcomes with CeAD receiving IAT versus (a) CeAD not treated with IAT, (b) CeAD receiving intravenous thrombolysis (IVT) alone, and (c) non-CeAD mechanism of AIS receiving IAT.DesignDemographics, clinical characteristics, treatment, and outcomes were summarized for all CeAD patients treated with IAT from January 2010 to May 2015. Outcomes included favorable 90 day modified Rankin Scale (mRS) score of 0–2, symptomatic intracerebral hemorrhage (sICH), recanalization (Thrombolysis in Cerebral Infarction 2b-3), procedural complications, and mortality. Outcomes were analyzed with χ2 tests and multivariate logistic regression.ResultsThere were 161 patients with CeAD: 24 were treated with IAT and comprised our target population. Dissections were more common in the internal carotid (n=18) than in the vertebral arteries (n=6). All but one patient had intracranial embolus. IAT techniques included thrombectomy (n=19), IA thrombolysis (n=17), stent (n=14), and angioplasty (n=7). Outcomes included favorable 90 day mRS score of 0–2 in 63%, 4 deaths, 1 sICH, and 3 procedural complications. After adjustment, favorable mRS in our target population was similar to comparison populations: (a) in CeAD, IAT versus no IAT (OR 0.62, p=0.56); (b) In CeAD, IAT versus IVT alone (OR 1.32, p=0.79); and (c) IAT in CeAD versus non-CeAD mechanism of AIS (OR 0.58, p=0.34).ConclusionsIAT is a valid alternative therapeutic option for AIS caused by CeAD due to the low complication rate and excellent outcomes observed in this study.

Background Limited observational data are available on endovascular treatment in acute ischemic stroke due to cervical artery dissection. Three studies comparing endovascular treatment with standard medical therapy or intravenous thrombolysis in cervical artery dissection-related acute ischemic stroke did not demonstrate superiority of endovascular treatment. Efficacy and the choice of endovascular treatment technique in this setting remain to be established. Aims To assess the potential efficacy and safety of endovascular treatment compared to intravenous thrombolysis alone or to no revascularization treatment in our center. Methods We selected all consecutive patients with cervical artery dissection-related acute ischemic stroke and intracranial occlusion from the Acute STroke Registry and Analysis of Lausanne between 2003 and 2017. We compared clinical and neuroimaging data of patients treated by endovascular treatment versus patients receiving intravenous thrombolysis or patients without revascularization treatment. Safety analysis included symptomatic intracranial hemorrhage, major radiological hemorrhages (parenchymal hematoma 1, parenchymal hematoma 2, and subarachnoid hemorrhage) and mortality within seven days. We assessed favorable clinical outcome (modified Rankin Scale 0-2) at three months using a binary logistic regression model. Results Of the 109 patients included, 24 had endovascular treatment, 38 received intravenous thrombolysis alone, and 47 had no revascularization treatment. Endovascular treatment patients had a higher rate of recanalization at 24 h. Major radiological hemorrhages occurred more often in endovascular treatment patients (all with bridging therapy) than in patients without revascularization treatment (p = 0.026), with no differences in symptomatic intracranial hemorrhage or mortality within seven days. Favorable clinical outcome at three months did not differ between groups (endovascular treatment versus intravenous thrombolysis p = 0.407; endovascular treatment versus no revascularization treatment p = 0.580). Conclusions In this single-center cohort of cervical artery dissection-related acute ischemic stroke with intracranial occlusion, endovascular treatment with prior intravenous thrombolysis may increase the risk of major radiological but not symptomatic intracranial hemorrhage. Despite the lack of clear superiority in our cohort, endovascular treatment should currently not be withheld in these patients.

Objectives: Strokes associated with cervical artery dissection have been managed primarily with antithrombotics with poor outcomes. The additive role of endovascular thrombectomy remains unclear. The objective was to perform systematic review and meta-analysis to compare endovascular thrombectomy and medical therapy for acute ischemic stroke associated with cervical artery dissection. Methods: Studies from six electronic databases included outcomes of patient cohorts with acute ischemic stroke secondary to cervical artery dissection who underwent treatment with endovascular thrombectomy. A meta-analysis of proportions was conducted with a random-effects model. Modified Rankin score at 90 days (mRS 0-2) was the primary outcome. Other outcomes included proportion of patients with thrombolysis in cerebral infarction (TICI) 2b-3 flow, 90-day mortality rate, and 90-day symptomatic intracerebral hemorrhage (sICH) rate. Results: Six studies were included, comprising 193 cases that underwent thrombectomy compared with 59 cases that were managed medically. Successful recanalization with a pooled proportion of thrombolysis in cerebral infarction (TICI) 2b-3 flow in the thrombectomy group was 74%. Favorable outcome (mRS 0-2) was superior in the pooled thrombectomy group (62.9%, 95% CI 55.8-69.5%) compared medical management (41.5%, 95% CI 29.0-55.1%, P=0.006). The pooled rate of 90-day mortality was similar for endovascular vs medical (8.6% vs 6.3%). The pooled rate of symptomatic intracranial haemorrhage (sICH) did not significantly differ (5.9% vs 4.2%, P=0.60). Conclusions: Current data suggest that endovascular thrombectomy may be an option in patients with acute ischemic stroke due to cervical artery dissection. This requires further confirmation in higher quality prospective studies.

BackgroundDespite successful recanalization after endovascular treatment, many patients with acute ischemic stroke due to large vessel occlusion still show functional dependence, namely futile recanalization.MethodsPubMed and Embase were searched up to April 30, 2021. Studies that reported risk factors for futile recanalization following endovascular treatment of acute ischemic stroke were included. The mean difference (MD) or odds ratio (OR) and 95% confidence interval (95% CI) of each study were pooled for a meta-analysis.ResultsTwelve studies enrolling 2138 patients were included. The pooled analysis showed that age (MD 5.81, 95% CI 4.16 to 7.46), female sex (OR 1.40, 95% CI 1.16 to 1.68), National Institutes of Health Stroke Scale (NIHSS) score (MD 4.22, 95% CI 3.38 to 5.07), Alberta Stroke Program Early CT Score (ASPECTS) (MD −0.71, 95% CI −1.23 to –0.19), hypertension (OR 1.73, 95% CI 1.43 to 2.09), diabetes (OR 1.78, 95% CI 1.41 to 2.24), atrial fibrillation (OR 1.24, 95% CI 1.01 to 1.51), admission systolic blood pressure (MD 4.98, 95% CI 1.87 to 8.09), serum glucose (MD 0.59, 95% CI 0.37 to 0.81), internal carotid artery occlusion (OR 1.85, 95% CI 1.17 to 2.95), pre-treatment intravenous thrombolysis (OR 0.67, 95% CI 0.55 to 0.83), onset-to-puncture time (MD 16.92, 95% CI 6.52 to 27.31), puncture-to-recanalization time (MD 12.37, 95% CI 7.96 to 16.79), and post-treatment symptomatic intracerebral hemorrhage (OR 6.09, 95% CI 3.18 to 11.68) were significantly associated with futile recanalization.ConclusionThis study identified female sex, comorbidities, admission systolic blood pressure, serum glucose, occlusion site, non-bridging therapy, and post-procedural complication as predictors of futile recanalization, and also confirmed previously reported factors. Further large-scale prospective studies are needed.

Background and Purpose: As lower doses of alteplase reduce the risk of symptomatic intracerebral hemorrhage (sICH), older and Asian people may benefit more from low-dose alteplase than other patients with acute ischemic stroke (AIS). Methods: Data from the ENhanced Control of Hypertension ANd Thrombolysis strokE study (ENCHANTED), an international, multi-center, prospective, randomized, open-label, blinded-endpoint trial, were analyzed to assess effects of low- (0.6mg/kg body weight) vs. standard-dose (0.9mg/kg) alteplase in AIS patients, by age and ethnicity (Asian vs. non-Asian), pre-specified subgroup analyses, on key efficacy and safety outcomes. Results: 3297 patients (1248 female), mean age 67 years were included. After adjusting for baseline characteristics and management variables over the first seven days, increasing age was associated with poor outcome, defined by ordinal analysis of the modified Rankin score (mRS) (shift to a less favorable outcome, P trend <0.0001). In the comparison between low- and standard-dose alteplase, no significant differences were observed for 90-day poor outcome by age deciles and ethnicity. Less sICH was observed with low-dose alteplase, and this was consistent for age and ethnicity. There was no ethnic difference in the treatment effects by age, severity, and time to treatment. Conclusions: Increasing age predicts poor outcome in thrombolysis-treated AIS patients. There was no heterogeneity in the treatment effects of low- vs. standard-dose alteplase. Decisions about intravenous thrombolysis should be based on variables other than age and ethnicity.
