Results of Endovascular Treatment for Infrapopliteal Arterial Occlusive Disease: a Prospective, Multicenter, Real-world Study

This study is a prospective, multi-center observational study, which evaluates the effectiveness and safety of endovascular therapy in the real world for infrapopliteal arterial occlusive disease from intermittent claudication to chronic threatening limb ischemia.

This study is a prospective, multi-center observational study. This study will be conducted at 38 centers and is expected to enroll more than 3000 patients. And we will evaluate the effectiveness and safety of endovascular therapy in the real world for infrapopliteal arterial occlusive disease from intermittent claudication to chronic threatening limb ischemia.

Inclusion Criteria:

Patients ≥ 18 years of age; Patients with ≥1 infrapopliteal artery disease (P3 popliteal artery, anterior tibial artery, posterior tibial artery, peroneal artery, tibiofibular trunk) need to receive endovascular treatment, regardless of whether there is a combination of supra-knee or submalleolar occlusion; Patients voluntary and capable of follow-up;

Exclusion Criteria:

Patients who are known to be allergic to heparin, aspirin, other antiplatelet drugs, contrast agents, etc., and those who are unable to undergo endovascular therapy for other reasons; Pregnant and lactating women; Patients with thromboangiitis obliterans；
