Arteriosclerosis; Extremities Clinical Trial
Official title:
A Prospective, Multicenter Study On the Effects of Progressive and Matched Caliber Balloon Predilation of Popliteal Artery On Treatment Strategy and Prognosis
In the endoscopic treatment of superficial femoral artery and/or proximal popliteal artery in patients with lower extremity arteriosclerosis occlusion, the intercalation caused by the predilation of increasing caliber balloon and matching caliber balloon was compared, and then the impact of the two predilation methods on the intraoperative treatment strategy and short and medium-term prognosis was analyzed. The study was designed as a prospective, multi-center, single-blind, randomized, controlled study. It is planned to set up 5-10 research centers with 340 subjects, and the single center will be less than or equal to 100 subjects, in the form of competition from each research center.
