Endovascular thrombectomy for tandem acute ischemic stroke associated with cervical artery dissection: a systematic review and meta-analysis

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.

The Impact

Background. The impact of renal impairment (RI) on the outcomes of patients with acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT) was relatively limited and contradictory. We performed a systematic review and meta-analysis to investigate this. Aims. We registered a protocol on September 2020 and searched MEDLINE, EMBASE, and Google Scholar accordingly. RI was defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2. Predefined outcomes included functional independence (defined as a modified Rankin Scale of 0, 1, or 2) at 3 months, successful reperfusion, mortality, and symptomatic intracerebral hemorrhage (sICH). Summary of review. Eleven studies involving 3453 patients were included. For the unadjusted outcomes, RI was associated with fewer functional independence (odds ratio (OR), 0.49; 95% confidence interval (CI), 0.39â0.62) and higher mortality (OR, 2.55; 95% CI, 2.03â3.21). RI was not associated with successful reperfusion (OR, 0.80; 95% CI 0.63â1.00) and sICH (OR, 1.41; 95% CI, 0.95â2.10). For the adjusted outcomes, results derived from a multivariate meta-analysis were consistent with the respective unadjusted outcomes: functional independence (OR, 0.59; 95% CI, 0.45â0.77), mortality (OR, 2.23, 95% CI, 1.45â3.43), and sICH (OR, 1.34; 95% CI, 0.85â2.10). Conclusions. We presented the first systematic review to demonstrate that RI is associated with fewer functional independence and higher mortality. Future EVT studies should publish complete renal eGFR data to facilitate prognostic studies and permit eGFR to be analyzed in a continuous variable.

Objective: The optimal management for cervical artery dissection (CAD) is uncertain. This study aimed to summarize the current randomized controlled trials (RCTs) to compare the efficacy and safety of antiplatelet and anticoagulation therapies for CAD.Methods: A literature search was conducted in the major databases, such as MEDLINE, Embase, and the Cochrane Library. Only the RCTs comparing the antiplatelet and anticoagulation therapies for the patients with CAD were included. Combined estimates of the relative risk (RR) of antiplatelet vs. anticoagulation were analyzed. Heterogeneity was measured using the I2 statistical analysis. The analyses were performed in the intention-to-treat (ITT) and per-protocol (PP) population, respectively.Results: Two RCTs involving 444 patients in the ITT population and 370 patients in the PP population were included. The quality of studies was high overall. In the ITT population, compared with the patients in the anticoagulation group, the patients in the antiplatelet group showed a higher rate of ischemic stroke within 3 months (RR = 6.73 [95% CI, 1.22–37.15], I2 = 0%, P = 0.029). No difference between these two treatment groups was found for the outcomes of transient ischemic attack (RR = 0.37 [95% CI, 0.09–1.58], I2 = 0%, P = 0.181), intracranial hemorrhage (RR = 0.33 [95% CI, 0.01–7.98], I2 = 0%, P = 0.494), major extracranial bleeding (RR = 0.31 [95% CI, 0.01–7.60], I2 = 0%, P = 0.476), or the composite of these outcomes within 3 months. For the PP population, the results of the meta-analysis of outcomes between the antiplatelet and anticoagulation groups were consistent with the ITT population.Conclusions: Compared with the antiplatelet group, the anticoagulation group has a lower risk of ischemic stroke without increasing bleeding risk when treating CAD. Anticoagulation seems to be superior over the antiplatelet in treating CAD but needs to be further tested by specifying several issues, such as location, initial symptom types, and treatment protocols.

Objective: We evaluated the current evidence on the association between migraine, including aura status, and cervical artery dissection. Methods: We performed a systematic review and meta-analysis of studies investigating the association between migraine or migraine subtypes (e.g. migraine with aura) and cervical artery dissection published through October 2010. Results: We identified five case-control studies investigating the association between migraine and cervical artery dissection. In pooled analysis, migraine doubled the risk of cervical artery dissection (pooled odds ratio [OR] = 2.06, 95% confidence interval [CI] 1.33–3.19). All studies allowed evaluation of migraine aura status. While the effect estimate for migraine without aura (pooled OR = 1.94, 95% CI 1.21–3.10) was similar to overall migraine, the association was weaker for migraine with aura (pooled OR = 1.50, 95% CI 0.76–2.96). However, there is no evidence that aura status significantly modifies the association between migraine and cervical artery dissection (meta-regression on aura status p = .58). The risk does not appear to differ between women and men; however, only few studies presented gender-specific data. Heterogeneity among studies was low to moderate. Conclusion: In this meta-analysis migraine is associated with a two-fold increased risk of cervical artery dissection. This risk does not appear to significantly differ by migraine aura status or gender.

Endovascular Thrombectomy

Background: Most trials for the endovascular thrombectomy (EVT) of large vessel ischemic stroke excluded patients with large core infarcts and low Alberta Stroke Program Early CT Score (ASPECTS). As a result, the current American Heart Association guidelines for acute ischemic stroke reserve Grade 1A recommendation for the use of EVT for patients with an ASPECTS of 6 or more. However recent data from the HERMES collaboration has shown that even stroke patients with large core infarcts may still benefit from EVT. Objectives: Through this systematic review, we aim to determine the safety and efficacy of EVT for large vessel ischemic stroke patients with low ASPECTS (5 or less). Methods: Medline, Cochrane Central Register of Systematic Reviews and ClinicalTrials.gov were searched for studies appraising the outcomes of EVT for low ASPECTS acute ischemic stroke patients. Patients with low ASPECTS who underwent EVT were compared to those who only received best medical therapy (BMT). A meta-analysis of proportions was done to compare the outcomes of the two groups in terms of symptomatic intracranial hemorrhage, mortality and good 3-month functional outcomes (modified Rankin Scale < 2). Results: Nine studies with a total of 1,196 acutes stroke patients with low ASPECTS (712 undergoing EVT and 484 with only BMT) were included in the study. There was a trend towards a higher rate of sICH in the EVT group (9.2%; 95% CI 6.1% to 13.6%; I 2 53.37%) compared to the BMT group (5.5%; 95% CI 3.7% to 8.1%; I 2 =0%) but this did not reach statistical significance (p=0.11). There was no difference (p=0.41) in the pooled 3-month mortality of EVT patients (30.7%; 95% CI 21.7 to 41.5%; I 2 84.23%) and BMT patients (36.6%; 95% CI 26.4% to 48.1%; I 2 76.2%). Patients who underwent EVT had significantly better (p=0.001) 3-month outcomes, with 27.7% (95% 21.8 to 34.5%; I 2 62.08%) of patients attaining an MRS 0-2 compared to only 3.7% (95% 2.3 to 5.9%; I 2 87.21%) of patients in the BMT. Conclusion: Our meta-analysis suggests that acute stroke patients with low ASPECTS score may still benefit from EVT. Larger registry based studies and randomized controlled trials are needed to further substantiate the findings of our review.
