Comparing Single Versus Multiple Infrapopliteal Artery Angioplasty for Treating Chronic Limb Threatening Ischemia and Their Effects on Limb Salvage Rates

What this Trial Is About

Researchers are evaluating the effectiveness of single vessel versus multiple vessel infrapopliteal angioplasty in patients with chronic threatening limb ischemia. This study aims to compare limb salvage rates and clinical outcomes among different treatment approaches over a follow-up period. The study is interventional and assesses how these procedures impact blood flow restoration and limb preservation in affected patients. Participants will receive balloon angioplasty, a procedure performed using standard balloon catheters under fluoroscopic guidance to open blocked infrapopliteal arteries. There are three study groups one receiving angioplasty of all three infrapopliteal arteries, another receiving angioplasty of two arteries, and a third group treated on only one artery. This allows comparison of outcomes based on the number of vessels treated. During the study, participants will be monitored for limb salvage at 6 months, with an optional follow-up at 12 months to assess long-term results. Researchers will observe clinical outcomes related to blood flow restoration and limb health. The study involves no masking or randomization, and participants will be followed closely to evaluate the effectiveness of each angioplasty approach in preserving the affected limb.
