Clinical investigation evaluates aspiration thrombectomy outcomes in middle cerebral artery M2 occlusions, highlighting treatment feasibility for distal strokes.
Purpose: The benefits of endovascular mechanical thrombectomy in patients with large vessel occlusion involving the internal carotid artery or the middle cerebral artery (MCA) M1 segment have been proven in several recent randomized trials. However, the efficacy of mechanical thrombectomy in patients with distal occlusion of the MCA M2 segment was controversial in these trials. Our study aimed to prove the efficacy and safety of aspiration thrombectomy performed in patients with M2 occlusion using the Penumbra 4MAX aspiration catheter.
