The aim of this study is to compare the effect of conscious sedation (CS) with general anesthesia (GA) on clinical outcomes in patients with acute ischemic stroke (AIS) undergoing endovascular therapy (EVT). MEDLINE, EMBASE, and Cochrane Central Registers of Controlled Trials (from inception to July 2017) were searched for reports on CS and GA of AIS undergoing EVT. Two reviewers assessed the eligibility of the identified studies and extracted data. Data were analyzed using the fixed-effects model, and the sources of heterogeneity were explored by sensitive analysis. Trial sequential analysis was conducted to monitor boundaries for the limitation of global type I error, and GRADE system was demonstrated to evaluate the quality of evidence. A total of thirteen studies were finally identified. Pooled analysis of the incidence of mRS score ≦ 2 after hospital discharge and one or three months in the CS group was higher than that in the GA group. The all-causing mortality of AIS patients in the CS group was lower than that in the GA group. There were no differences in the proportion of IA rtPA and thrombolysis between the two groups. Compared with AIS patients receiving GA, the all-causing mortality in the AIS patients receiving CS was decreased, while incidence of mRS score ≦ 2 at hospital discharge and one or three months was increased.

Introduction: Endovascular (intra-arterial, IA) therapy for acute ischemic stroke has become part of acute therapy , but limited randomized clinical trials have had inconsistent results. We sought to evaluate efficacy and safety of endovascular therapy in - randomized clinical trials . Methods: We performed a systematic review of literature for randomized clinical trials of endovascular therapy with thrombolytic or mechanical reperfusion compared with comparator groups without IA therapy. Use of systemic thrombolysis was not excluded. Primary outcome was modified Rankin scale of disability of 0-2 at 90 days and secondary outcomes of mortality at 90 days and symptomatic intracranial hemorrhage was noted. Two groups of independent reviewers searched and identified studies and abstracted data. Random-effects meta-analysis was performed. Subgroups were analyzed by study design characteristics. Results: Systematic search identified 10 studies with 1572 subjects, of which 9 studies reported the primary outcome. IA therapy was associated with good outcome at 90 days (Odds ratio (OR) =1.28; 95% CI, 1.01 to 1.62; p=0.04), but there was significant heterogeneity with p of 0.03. Among 3 trials (n=1136) comparing mechanical thrombectomy with control, mechanical thrombectomy was not superior to control with good outcome (OR=0.98; 95 % CI, 0.85 to 1.14; p=0.83). Patients with IA therapy significantly have good outcome in studies without systematic thrombolysis in the comparator (OR=1.55; 95 % CI, 1.05 to 2.29; p=0.03) and required vessel occlusion for randomization (OR=1.54; 95 % CI, 1.10 to 2.14; p=0.01). Mortality was unchanged with IA therapy (OR=0.92; 95 % CI, 0.75 to 1.13; p=0.45) and there was no difference in symptomatic hemorrhage (OR=1.13; 95 % CI, 0.74 to 1.74; p=0.56). Conclusion: IA therapy has a small but significant increase in good outcomes for patients with acute ischemic stroke without increasing mortality and symptomatic hemorrhages.

<b><i>Objective:</i></b> We performed a systematic review and meta-analysis to investigate the clinical significance of hyperdense area after thrombectomy in patients with acute ischemic stroke (AIS). <b><i>Methods:</i></b> We searched Ovid MEDLINE(R) and Epub Ahead of Print, In-Process and other Non-Indexed, Cochrane Library Clinical Controlled Trials and Embase from inception to September 2020 and collected the cohort and case-control studies about the clinical significance of hyperdense area on different types of computed tomography (CT) after thrombectomy in patients with AIS. Outcomes were poor functional outcome (modified Rankin Scale [mRS] Score 3–6 at discharge or 90-day), mortality and subtypes of hemorrhage according to the European Cooperative Acute Stroke Study (ECASS). <b><i>Results:</i></b> 1,999 patients from 16 studies were included in this meta-analysis. Pooled results indicated higher risk of symptomatic intracerebral hemorrhage (odds ratio [OR] = 3.02; 95% confidence interval [CI] 1.84–4.95; <i>p</i> &#x3c; 0.0001, <i>I</i><sup>2</sup> = 0%) in patients with hyperdense area, and the subtype of parenchymal hematoma as well. There was also higher odds of poor functional outcome based on the mRS 3–6 at discharge or 90-day (OR = 1.92; 95% CI 1.35–2.73; <i>p</i> = 0.0003, <i>I</i><sup>2</sup> = 31%) and mortality (OR = 2.06; 95% CI 1.41–3.02; <i>p</i> = 0.0002, <i>I</i><sup>2</sup> = 0%) in patients with hyperdense area after thrombectomy compared with those without hyperdense area. <b><i>Conclusions:</i></b> Our results indicated that the presence of hyperdense area on CT after thrombectomy was associated with high risk of symptomatic intracerebral hemorrhage, poor functional outcome, as well as mortality in patients with AIS. However, further studies were needed to confirm these results. The meta-analysis was conducted in adherence with the PRISMA Statement and was registered at the International Prospective Register of Systematic Reviews (CRD42020164165). To the best of our knowledge, this study is the first meta-analysis investigating the effect of hyperdense area after endovascular therapy in patients with AIS.
