Safety and Efficacy of Thrombectomy for Distal Medium Vessel Occlusions of the Middle Cerebral Artery.

ABSTRACT:

Purpose

Mechanical thrombectomy (MT) for distal medium vessel occlusions (DMVOs) in the middle cerebral artery (MCA) is less established than for large vessel occlusions. This study evaluates the safety and efficacy of MT in DMVOs, comparing it with M1-segment occlusions.

Materials and methods

This retrospective study analyzed 218 patients who underwent MT for isolated M1 (n=123) or distal M2+M3 (n=35) occlusions between January 2020 and August 2023. Outcomes included procedural complications, hemorrhagic events, reperfusion rates, and clinical severity and disability at admission and discharge. Multivariate logistic regression identified predictors of favorable outcomes (modified Rankin Scale≤2) at discharge.
