Abstract

Objective: To evaluate functional and safety outcomes of Endovascular thrombectomy(EVT) vs Medical Management(MM) in patients with M2 occlusion and examine their association with perfusion imaging mismatch and stroke severity.

Methods: In a pooled, patient-level analysis of 3 randomized controlled trials(EXTEND-IA, EXTEND-IA-TNK part 1&2) and 2 prospective non-randomized studies(INSPIRE&SELECT), we evaluated EVT association with 90-day functional independence(mRS 0-2) in isolated M2 occlusions as compared to medical management overall and in subgroups by mismatch profile status and stroke severity.

Results: We included 517 patients(EVT=195, MM=322), baseline median(IQR) NIHSS was 13(8-19) in EVT vs 10(6-15) in MM, p

Interpretation: In patients with M2 occlusion, EVT was associated with improved clinical outcomes when compared to medical management. This association was primarily observed in patients with a mismatch profile and those with higher stroke severity. This article is protected by copyright. All rights reserved.
