Objectives : The 5MAX ACE is a new large bore aspiration catheter availablefor vessel recanalization for treatment of acute ischemic stroke (AIS). We report our initial experience with its use. Methods : A retrospective analysis of patients undergoing intra-arterialtherapy for AIS using the 5MAX ACE reperfusion catheter at our institutionwas performed. Patient demographics, clinical characteristics andprocedural data were obtained from chart review. Successful recanlizationwas defined as achievement of Thrombolysis in Cerebral Infarction score(TICI) 2b-3 and time to recanalization was defined as time from groinpuncture to achievement of at least TICI 2b recanalization. Results : The 5MAX ACE was used in 15 patients from July-October2013. Direct aspiration was used as the primary technique in 10/15(67%) patients. Out of these, aspiration alone was sufficient for recanalizationin 3 (20%) patients. In the remaining 7 (47%) patients, additionaldevices were used. In 5/15 (33%) patients, combined aspiration/stentrieverthrombectomy using Solitaire™ (3/5 patients) and Penumbra 3DSeparator™ (2/5 patients) were used as the primary technique. Successfulrecanlization (TICI 2b-3) was achieved in 11/15 (73%) patients. Averagetime from groin puncture to successful recanalization was 46 +/- 30 minutes(range 14-98 minutes). There were no procedural complications. Conclusion : The 5MAX ACE is a useful recanalization tool, either by directaspiration or combined stentriever/aspiration. It may be most advantageouswith large clots in the internal carotid artery. The potentialfor effective and faster recanalization using this device alone or in combinationmay be a good topic for future study.
