ABSTRACTAIM: To assess the safety and efficacy of distal thrombectomy (DT) using a Catch View mini (CVm) device via a microcatheter witha 0.013-inch inner diameter.MATERIAL and METHODS: Nine of 246 acute ischemic stroke patients who underwent mechanical thrombectomy developeddistal emboli and were included in the study. In all nine subjects (mean age, 64.5 ± 11.6; range, 39−77 years), a combination of CVmand a 0.013-inch microcatheter was used in distal mechanical thrombectomy. Modified Thrombolysis in Cerebral Ischemia scoresof 2c and 3 were considered to indicate successful recanalization, and patients with a Modified Rankin Score of ≤ 2 on the 90th daywere considered to have good clinical outcomes.RESULTS: Eleven DT maneuvers were performed using the same stent retriever and microcatheter. The mean National Institutes ofHealth Stroke Scale score was 13 ± 3.4. Thrombectomy was performed from M3 in six patients, A3 in four, and P3 in one. Successfulrecanalization was achieved in all of the procedures. The rate of good clinical outcome was 55.5%.CONCLUSION: Advances in technology in the endovascular field enable access to more distal vessels in acute ischemic stroke. Asthe profile of the instruments used during access decreases, the risk of complications may decrease. The CVm stent retriever couldbecome a useful tool in DT based on its compatibility with a 0.013-inch lumen delivery system.
