Abstract

This is asystematic review and meta-analysis of randomized controlled trials (RCTs) conducted to elucidate if pre-treatment with intravenous thrombolysis is necessary before thrombectomy. A total of 6 RCTs conducted from January 2019 to March 2022 were selected to meta-analyze, including DIRECT-MT trial, DEVT trial, SKIP trial, MR CLEAN-NO IV trial, SWIFT-DIRECT trial, and DIRECT-SAFE trial. In terms of good outcomes (mRS 0-2 at 90 days), thrombectomy alone was non-inferior to combination therapy at the non-inferiority margin of -6%. The successful reperfusion rates were lower in thrombectomy alone, but symptomatic intracerebral hemorrhage rates were also lower in this therapy. Thrombectomy alone may be a reasonable option for patients at high risk of hemorrhagic transformation following revascularization.
