Aims: Diabetic patients in India present late in advanced stages of tissue loss and isolated occlusive infrapopliteal disease. We aim to determine the outcomes of angioplasty in these patients with SINBAD score >3 and infrapopliteal disease presenting with critical limb-threatening ischemia (CLTI) and tissue loss. Materials and Methods: A prospective, observational, single-center study was carried out of diabetic patients with infrapopliteal occlusive disease who underwent angioplasty for CLTI and tissue loss. Transatlantic society consensus (TASC) - classification was used for staging. Ischemia and Peripheral Artery Calcium Scoring was used to assess peripheral calcium. The patients were followed up till their ulcer healed and then every six months. Results: A total of 73 diabetic patients underwent angioplasty for CLTI. 21.8% (16/73) all-cause mortality was seen during the study. The average age was 68.9 years with 78.9% males. The average time to presentation was 55 days. 61.3% of patients had TASC C or D lesions. Technical success was achieved in 94.5% of patients. 27.4% of patients underwent angioplasty of multiple tibial vessels. The mean duration of follow-up was 2 years. 62.5% of patients had their ulcers completely heal in 6 months. Six patients went on to have major amputation. The amputation-free period was 500 days in this patient group. Ulcer healing was found to be dependent on successful revascularization. Conclusion: Mortality is seen in 1 in 10 and morbidity in 1 in 5 patients. It is difficult to accurately prognosticate healing in these patients. Successful revascularization is the only factor affecting healing in these patients.
