Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Incrementing groups

Each of the Increased caliber balloon capsules was predilated one by one, and the order of the increased balloon capsules was as follows: Balloon 2 diameter = target lesion reference vessel diameter minus 1; Balloon 3 diameter = target lesion reference vessel diameter;

Group Type EXPERIMENTAL

Increased caliber balloon

Intervention Type DEVICE

Imaging of target lesions was performed before surgery to evaluate the characteristics of target lesions.

Postoperative to discharge Laboratory examination: blood routine, renal function, biochemical, coagulation functionTo determine and record the ABI(ankle-brachial pressure index);Records Rutherford classification; record the application of anticoagulant and antiplatelet agents; Records of adverse events.

matching groups

Pre-dilatation of the matched caliber balloon, whose diameter = the target lesion's diameter as a reference vessel, was applied.

Group Type EXPERIMENTAL

matched caliber balloon

Intervention Type DEVICE

Imaging of target lesions was performed before surgery to evaluate the characteristics of target lesions.

Postoperative to discharge Laboratory examination: blood routine, renal function, biochemical, coagulation functionTo determine and record the ABI index;Records Rutherford classification; record the application of anticoagulant and antiplatelet agents; Records of adverse events.
