Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There have been a number of randomized controlled studies (RCT) showing the efficacy of the endovascular treatment with drug-coated balloons (DCB) in the femoropopliteal artery lesions. However, these studies have been carefully designed, and most of them have excluded long-length lesions and severely calcified lesions. In addition to being used alone in the real word, drug-coated balloons (DCB) are also used in combination with stents or debulking devices, but in these randomized controlled studies (RCT) they are only compared with standard percutaneous transluminal angioplasty (PTA). Therefore, the investigators initiated this study, which is a prospective, multicenter, observational real-world study of short and long-term outcome in endovascular treatment of femoropopliteal arterial occlusive lesions with DCB.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Traditional endovascular approaches to the treatment of atherosclerotic disease in the femoropopliteal arteries include percutaneous transluminal angioplasty (PTA) with an uncoated balloon and implantation of a bare metal stent. Recently, drug-eluting stents (DES) and drug-coated balloons (DCB) that transfer paclitaxel to the vessel wall during revascularization have been added to the suite of tools available to interventionists, helping to prevent restenosis after treatment.

There have been a number of randomized controlled studies (RCT) showing the efficacy of the endovascular treatment with drug-coated balloons (DCB) in the femoropopliteal artery lesions. However, these studies have been carefully designed, and most of them have excluded long-length lesions and severely calcified lesions. In addition to being used alone in the real word, drug-coated balloons (DCB) are also used in combination with stents or debulking devices, but in these randomized controlled studies (RCT) they are only compared with standard percutaneous transluminal angioplasty (PTA).

Therefore, the investigators initiated this study, which is a prospective, multicenter, observational real-world study of short and long-term outcome in endovascular treatment of femoropopliteal arterial occlusive lesions with DCB. It is estimated that 1200 patients with chronic femoral popliteal artery occlusion were enrolled in the group at 8 centers in China in two years. The follow-up would be conducted at 1, 3, 6, 12, 18, 24, 36 and 48 months after the operation to assess the efficacy and safety of the endovascular treatment with drug-coated balloons (DCB) in the femoropopliteal artery lesions.
