Trevo 6 × 25mm vs. 4 × 30mm in Mechanical Thrombectomy of M1 LVO.

Our primary objective was to determine the successful rate of recanalization of M1 large vessel occlusion using either the Trevo 4 × 30 mm or 6 × 25 mm stent during mechanical thrombectomy. Our secondary objectives were to determine differences between the use of these two stent retrievers regarding first-pass effect, periprocedural complications, and mortality in the first 90 days. This is a retrospective cohort study.
