Infra-popliteal arteries are frequently involved in CLTI, especially in diabetic and elderly patients, posing significant challenges due to diffuse, calcified, and long-segment occlusive lesions.\n\nConventional balloon angioplasty remains a first-line endovascular treatment but is limited by high restenosis and vessel recoil rates. Atherectomy, a plaque debulking technique, aims to improve luminal gain and vessel compliance prior to angioplasty, potentially enhancing outcomes in heavily calcified lesions. The combination of atherectomy and balloon angioplasty has shown promise in reducing dissection rates and improving technical success, yet its superiority over conventional angioplasty alone remains controversial.\n\nGiven the growing use of endovascular therapies, a comparative analysis of outcomes between combined atherectomy-balloon angioplasty and conventional angioplasty in infra-popliteal interventions is essential to guide evidence-based management in CLTI patients.",[54],"Chronic Limb Threatening Ischemia","NOT_YET_RECRUITING","2025-08-12",{"date":58,"type":59},"2025-08-13","ACTUAL",{"date":61,"type":48},"2025-09-30",{"date":63,"type":48},"2027-12-30",{"name":5,"class":6}]
