Intermediate and Long-term Efficacy of Endovascular Treatment for TASC C&D Aortoiliac Occlusive Disease: a Prospective, Multicenter, Real-world, Registry Study
This study is a prospective, multi-center, real world, observational study, which aims at evaluating the intermediate and long-term efficacy of endovascular treatment for TASC C\&D aortoiliac occlusive disease .It is estimated that 800 subjects diagnosed with TASC C\&D aortoiliac occlusive disease and receive endovascular treatments will be enrolled in nine centers from April 2021 to June 2027 nation-widely. All the subjects will be under follow-up for 60 months. There is no restriction on the endovascular techniques. The primary outcomes covers freedom from TLR at 60 months.
• Rutherford grades 3-6.
• Follow the follow-up arrangement.
• Age: 18-80 years old.
• The target lesions were in the lower abdominal aorta and/or the common iliac artery and/or the external iliac artery.
• The stenosis degree ≥50%, or restenosis (received PTA or other adjuvant therapy, including bare or covers stents), or complete occlusion, or the presence of aortailiac artery thrombosis after PMT or CDT thrombus clearance, and then further endovascular therapy perfomred.
• Signed informed consent.
