About this study
This study is a prospective, multicenter real-world observational study to understand the safety and efficacy of endoluminal therapy and traditional endometristomy in the real world for patients with severe stenosis and occlusion of the common femoral artery. The study will enroll 300 patients with severe stenosis and occlusion of chronic common femoral artery in nine centers across the country. According to the different intervention methods of the common femoral artery, the enrolled cases were divided into two groups: A: endometrial detachment for common femoral artery lesions and B: interventional endovascular treatment for common femoral artery lesions. As it is a real-world study, there is no separate primary endpoint indicator, which mainly observes F-TLR (immunity from vascular re-intervention), technical success rate, duration of surgery, length of hospital stay, common femoral artery patency rate, deep femoral artery patency rate, direct and indirect medical expenditure associated with the disease in 24 months, MAE (major adverse events), and perioperative complications.
