Effect of drug-coated balloon on restenosis and thrombosis after interventional treatment of femoral popliteal arteriosclerosis obliterans

Abstract

Objective To investigate the effect of drug-coated balloon on restenosis and thrombosis after interventional treatment of femoral popliteal arteriosclerosis obliterans. Methods Sixty-four patients with femoral popliteal arteriosclerosis occlusion who planned to receive interventional treatment in the 541th General Hospital of Yuncheng from June 2016 to January 2018 were selected. According to the random number table method, the patients were divided into control group and experimental group, with 32 cases in each group. The control group was treated with common balloon dilatation angioplasty, and the experimental group was treated with drug coated balloon dilatation angioplasty. The late lumen loss, the ankle brachial index (ABI) and restenosis, thrombus formation and amputation were compared between the two groups. Results The postoperative lumen loss of the superficial femoral artery and popliteal artery in the experimental group was less than that in the control group, and the difference was significant (P 0.05). Conclusions Drug coated balloon interventional therapy can improve the postoperative ABI, reduce the loss of the femoral popliteal artery lumen, reduce the restenosis rate and the rate of thrombosis.
