Objective:To analyze the application value of the mechanical thrombectomy system in the treatment of acute limb ischemia.Methods:The clinical data of 50 patients with lower limb ischemia who were treated with the Rotarex mechanical thrombectomy system from Jun 2017 to Sep 2019 were retrospectively analyzed.Results:In 4 cases of popliteal artery rupture occurred during the operation. The success rate of the operation was 92%. Catheter-directed thrombolysis was used in 7 cases, percutaneous transluminal angioplasty was used in 4 cases and percutaneous transluminal angioplasty combined with stent implantation was used in 39 cases. The ankle-brachial index of these 50 patients before and after operation was 0.18±0.24 and 0.64±0.28 respectively ( t=12.87, P<0.001). Treatment was successful in 43 cases. Follow-up ranged from 1 to 24 months, 5 cases were amputated, 2 cases had no improvement of toe ulcer gangrene, 9 cases had thrombus recurrence, and no complications such as bleeding were observed. The primary patency rates at 3, 6 and 12 months were 92%, 84% and 74%, respectively. Conclusion:The mechanical thrombectomy system is safe and effective in the treatment of acute lower limb ischemia with ideal short-term patency.
