Abstract
INTRODUCTION:
Recanalization of occluded intracranial large vessels after endovascular thrombectomy (EVT) is often achieved following multiple attempts. Current literature does not offer any guidance regarding switching to alternative thrombectomy techniques (AT) after a futile first attempt.
METHODS:
We included patients with stroke secondary to large vessel occlusion (LVO) who failed their first attempt at recanalization of either ICA or M1 segments utilizing an international multicenter cohort. Propensity score matching was then used to match patients with similar versus AT used as a second attempt on a 1:1 basis. Successful recanalization at the second attempt was the primary outcome while secondary outcomes consisted of functional outcomes at 90 days and postprocedural hemorrhage.
RESULTS:
10229 patients were included, 2167 of which failed first pass EVT. 1733(80%) patients were treated with the same technique while 434 (20%) patients were switched to an AT. Conversion to AT was associated with higher recanalization rate (aOR = 1.5, P=0.041), higher odds of mRS (0-2) at 90 days (aOR = 1.6, P=0.005), without increased post-procedural hemorrhage rate (P=0.379).
CONCLUSIONS:
Conversion to AT after futile first EVT attempt is associated with imporved technical and function outcomes at 90 days without additional complications.
