Rotarex debulking combined with paclitaxel drug-coated balloon in treatment of ischemia of lower limb artery / 中华普通外科杂志

ABSTRACT

Objective:To evaluate the effect of Rotarex debulking combined with paclitaxel drug-coated balloon in the treatment of ischemia of lower limb artery.Method:The clinical data of 34 patients who had lower extremity arterial ischemic disease treated by Rotarex debulking combined with paclitaxel drug-coated balloon from Nov 2016 to Sep 2018 was retrospectively analyzed.Results:There were male 25 cases, with an average age of (69±10) years, the lesion length was (216.7±110.0)mm, and the course of disease was(169.3±303.0) days. Fourteen (41.18%) had primary lesions, 8 (23.53%) had stent occlusion, 11 (32.35%) had primary+ stent occlusion, and 1 (2.94%) had primary+ artificial vascular thrombosis.The technical success rate was 97.06% (33/34), and 100% after catheter directed thrombolysis (CDT). Thirty patients (88.24%) received percutaneous transluminal angioplasty (PTA) and 6 patients (17.65%) received stent placement. The clinical success rate was 97.06% (33/34). There were 2 cases (5.88%) with distal vascular embolism during the operation, no bleeding or artery rupture. The ankle brachial index (ABI) (0.86±0.13) significantly increased (0.40±0.28) ( t=8.851, P<0.01). All patients were followed up for 12 months. The patency rate was 94.12% (32/34), 87.88% (29/33) and 75.76% (25/33) in 3, 6 and 12 months respectively. There was no death in perioperative period and no amputation above ankle in follow-up period. 93.94% of patients were free from clinical driven target lesions. Conclusion:Rotarex debulking combined with paclitaxel in the treatment of lower extremity arterial ischemic disease is safe and effective.
