Percutaneous transluminal stenting versus directional atherectomy for lower limb artery TASC II Class A and B superficial femoral artery lesions

Abstract

Objective To compare the effect and safety of stenting versus directional atherectomy(DA) in the treatment of TASCII A and B superficial femoral artery lesions. Methods 100 patients with TASCⅡ A and B lesions were divided into percutaneous transluminal stenting(PTS) group (n=50) and DA group (n=50). Patients were compared in terms of technical success rate, treatment success rate, first operation cost, postoperative ankle brachial index (ABI), limb salvage rate, survival, and patency. Results The technical success rate in both PTS and DA group was 100%.The treatment success rate was 98% vs. 86%, P>0.05. Postoperative ABI: 0.82±0.19 vs. 0.80±0.27, P>0.05. First operation cost: (34 820±1 051) yuan vs. (45 635±1 358) yuan, P 0.05). Limb salvage rate was 97.9% vs. 93.8 %, P>0.05. Conclusion There were no significant differences in the effect and safety of PTS versus DA in the treatment of TASCII A and B superficial femoral artery lesions.
