Brief Summary

This study is a prospective, single-center, observational study. In this study, we aim to evaluate the clinical outcome and cost-effectiveness of different treatments of lower extremity arterial occlusive disease. It is expected to include about 400 patients diagnosed with lower extremity arterial occlusive disease in our center from July 2024 to July 2026. All enrolled patients will be followed for three years. All patients diagnosed with arteriosclerosis obliterans (ASO) and all treatment techniques were included in this study. The primary outcomes include the Efficacy and Safety End Points of each techniques.

Study Arms (6)

Bypass group

open bypass group

Procedure: open bypass group

BMS group

BMS (bare metal stent) group

Procedure: bare metal stent group

POBA group

POBA (plain old balloon angioplasty) group

Procedure: plain old balloon angioplasty group

DCB group

drug-coated balloon group

Procedure: drug-coated balloon group

DA group

DA (directional atherectomy) group

Procedure: directional atherectomy group

HR group

HR (hybrid repair) group

Procedure: hybrid repair group

Interventions

After heparinization, the target artery is clamped above and below the anastomosis. The target artery is dissected along the anterior wall, calcium portions or mural thrombus are removed. Graft (autologous or prosthetic graft) is cut obliquely and anastomosis suturing starts with distal angle. Next stage is tunnel creating for graft conduction.

Bypass group

Bare metal stent implantation during the index procedure.

BMS group

Only plain old balloon was used during the index procedure.

POBA group

Drug-coated balloon was used during the index procedure.

DCB group

Directional atherectomy (with or without drug-coated balloon) during the index procedure.

DA group

Femoral artery arteriotomy. Further execute a direct endarterectomy femoral artery and from the mouth of a hip artery. Arteriotomy of the femoral artery is closed with a vascular patch use (synthetic or biological). Endovascular revascularization followed.

HR group
