Research progress of drug-coated balloons for the treatment of infrapopliteal artery disease

Abstract

Great progress has been made in devices and techniques for the endovascular treatment of peripheral artery diseases. The plain old balloon angioplasty, stent implantation and the emerging drug-coated balloon angioplasty have provided new means of treatment. In recent years, drug-coated balloons have been proved valuable by many clinical trials for the treatment of superficial femoral and proximal popliteal artery lesions. However, there are still insufficient evidence and much controversy about the role of drug-coated balloons in treating infrapopliteal lesions. This article will briefly review the current research status and progress of drug-coated balloons for the treatment of infrapopliteal lesions.
