A TOTAL OF 1599 PATIENTS FROM NINE STROKE CENTERS WERE TREATED WITH INTRA-ARTERIAL THROMBECTOMY USING STENT RETRIEVERS BETWEEN MARCH 2012 AND MARCH 2016. INTRAPROCEDURAL VESSEL PERFORATION DURING STENT RETRIEVER THROMBECTOMY OCCURRED IN 1.0% (16/ 1599) OF PATIENTS. VESSEL PERFORATION OCCURRED IN MOST CASES AT DISTAL LOCATIONS: MIDDLE CEREBRAL ARTERY (MCA) M2, ANTERIOR CEREBRAL ARTERY A2 AND POSTERIOR CEREBRAL ARTERY P2/3. ENDOVASCULAR RESCUE TECHNIQUES (MOST COMMONLY, INTRACRANIAL BALLOON OCCLUSION FOR TAMPONADE) WERE ATTEMPTED IN 50% OF CASES. PROCEDURE WAS ABORTED WITHOUT ANY RESCUE ATTEMPTS IN 44% OF CASES. MORTALITY DURING HOSPITALIZATION AND AT 3 MONTHS WAS 56% AND 63%, RESPECTIVELY; 25% OF PATIENTS ACHIEVED GOOD RESULTS.
