Seltoplasmid Plus Revascularization for Diabetic Infrapopliteal Chronic Limb-Threatening Ischemia

The goal of this clinical trial is to learn whether Seltoplasmid Injection can improve outcomes after lower-extremity revascularization. Revascularization is a procedure used to restore blood flow to the leg. The study will include adults with type 2 diabetes, a foot ulcer caused by poor blood flow, and disease mainly affecting the arteries below the knee. The main questions are: * Does adding Seltoplasmid lower the risk of major amputation, another procedure to restore blood flow, or death? * What medical problems occur after treatment with Seltoplasmid? About 180 participants will undergo standard lower-extremity revascularization. After the procedure, eligible participants will be assigned by chance to one of two groups. One group will receive Seltoplasmid plus standard care. The other group will receive standard care alone. Participants in the Seltoplasmid group will receive injections into the muscles of the affected lower leg. The injections will be given on Day 0, Day 14, and Day 28. Participants will be followed for 12 months. Researchers will also assess wound healing, survival without amputation, heart and blood vessel problems, pain, and blood flow in the affected leg.

an Observational Study Evaluting the Effectiveness and Safety of DKutting LL Noval Scoring Balloon Angioplasty for Vessel Preparation Facilitated by IVUS on the Lower Limb Ischemia Patients With Calcified Lesions

This is a prospective, single-center, single-arm, observational study. It plans to enroll 58 patients with moderate to severely calcified lesions in the femoropopliteal or infrapopliteal arteries. Participants will be treated with the Scoring Balloon Dilatation Catheter manufactured by DK Medtech (Suzhou) Co., Ltd. The study aims to evaluate the immediate technical success rate and the improvement in lumen area and calcification burden as assessed by IVUS following percutaneous transluminal angioplasty with the scoring balloon. Clinical follow-ups will be conducted at discharge (or within 7 days), 1 month, 3 months, and 6 months post-procedure to observe secondary endpoints including the incidence of clinically driven target lesion revascularization and changes in Rutherford classification

Revascularization of Single Vesrus Multiple Infrapopliteal Vessels in Chronic Limb Threatening Ischemia

This interventional prospective study aims to assess the effectiveness of single vessel versus multiple vessel infrapopliteal angioplasty in patients with chronic threatening limb ischemia . The study compares limb salvage rates and clinical outcomes across two groups over a defined follow up period
