Medium vessel occlusion thrombectomy: Single center experience using the 3 MAX catheter

Thrombectomy for medium vessel occlusion is a topic of great interest. We describe a single-center experience with the Penumbra 3-MAX aspiration catheter in stroke thrombectomy of medium vessel occlusion(MeVO). We investigated the use of 3-MAX as a de-novo first pass catheter and as a rescue aspiration device following attempted thrombectomy with other devices. This is the first description of the first pass effect and successful recanalization rate of the 3-MAX catheter in de-novo vs. rescue use of this catheter.
