Introduction: Endovascular therapy (EVT) is a treatment recommended for stroke patients with large vessel occlusion and an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) ≥6. However, the utility of EVT in patients with large core ischemic stroke has not been well established.

Methods: This meta-analysis assesses EVT's efficacy and safety using available trials comparing EVT to medical management (MM) in stroke patients with large ischemic core. Eligibility criteria: 1) were randomized controlled trials, 2) compared EVT with MM alone, 3) studied patients presenting with LIC cerebrovascular events, and 4) reported outcomes of interest. We extracted data for the major imaging inclusion criteria, the National Institutes of Health Stroke Scale (NIHSS) score, pre-stroke mRs score, and occlusion site. We also extracted outcome data for the EVT groups vs MM groups, including measurement of early neurological recovery, and definition of sICH.

Results: Our primary end point was the mean modified Rankin scale score (RSS) at 90-day follow up. EVT was associated with higher odds of significant improvement in functional status with reduction in mean mRS by -0.31 [-0.47; -0.14]) compared to MM. The odds of achieving mRS 0 to 2 was higher in the EVT arm compared to the MM arm (2.53 [1.59; 4.02]). There was no difference in achieving mRS 0 to 3, early neurologic improvement defined according to NIHSS score, overall 90-day mortality and risk of symptomatic ICH between patients treated with EVT or MM in our analysis.

Conclusions: Our study suggests that EVT may lead to improved outcomes in stroke patients with large core ischemia.
