Abstract 77: Comparative Efficacy of Different Acute Reperfusion Therapies for Acute Ischemic Stroke: A Comprehensive Meta-analysis of Clinical Trials

Background&Purpose: There are limited data directly comparing acute reperfusion therapies (RPT) for the treatment of acute ischemic stroke (AIS) in the setting of randomized controlled trials. We conducted a comprehensive meta-analysis of available clinical studies of acute RPT to indirectly compare them using a benefit-to-risk analysis. Subjects&Methods: We abstracted data from 16 RPT studies evaluating intravenous thrombolysis (IVT) using alteplase or tenecteplase (TAAIS, NINDS), sonothrombolysis (CLOTBUST) intra-arterial thrombolysis (PROACT I&II, IMS III, SYNTHESIS pilot&expansion study) and acute thrombectomy/thromboaspiration using different retrievers (MERCI, Multi-MERCI, PENUMBRA Pivotal Stroke Trial & Post Market Experience, SWIFT, TREVO, TREVO 2, MR Rescue). The benefit-to-risk ratio (BRR) was estimated separately for each study using the following formula: BRR= (% of 3-month mRS of 0-1/ % of 3-month mRS of 6) x (median baseline NIHSS of study of interest/median baseline NIHSS of all evaluated s...
