Abstract:
Objective: To observe the efficacy and safety of percutaneous mechanical thrombectomy (PMT) using Rotarex device for treatment of acute limb ischemia (ALI) caused by femoropopliteal artery thrombosis. Methods: Data of 22 patients with ALI caused by femoropopliteal artery thrombosis treated with PMT using Rotarex device were retrospectively analyzed. The therapeutic effect and complications were observed. Results: PMT was successfully performed in all 22 patients, combined with catheter-directed thrombolysis in 4 patients, with balloon dilatation in 17 and stent implantation in 12 patients. Femoropopliteal arteries were recanalized in all 22 patients, the technique success rate was 100%, and the ankle brachial index significantly increased after operation (P<0.05). After operation, improvement of Rutherford grade was observed in 21 except 1 patient who underwent resection of necrotic toes 3 weeks after operation. Distal artery embolism and vascular dissection occurred respectively in 1 patient during PMT. During follow-up period, in-stent reocclusion of the superficial femoral artery occurred in 1 patient 6 months after operation, while thrombus of the lower limb artery recurred in 1 patient 9 months after operation. Conclusion: PMT using Rotarex device is safe and feasible for treatment of ALI caused by femoropopliteal artery thrombosis.
