Catheter angiogram before and after thrombectomy for M3 occlusion

Given the patient’s aphasia and distal occlusion, the patient was taken for emergent catheter cerebral angiogram (A), which showed persistent M3 occlusion of the left middle cerebral artery posterior division. Following one pass of mechanical thrombectomy with a 3 mm by 30 mm stent retriever and 4 max ACE intermediate catheter, TICI 3 reperfusion was achieved (B), and the thrombus shown in (C) was retrieved.
