The Role of SFA lesion length in the success of percutaneous transluminal angioplasty for chronic limb-threatening ischemia

Background: Superficial femoral artery (SFA) lesions are a significant cause of critical limb ischemia (CLI). Particularly occlusion length, play an important role in management outcomes. Objectives: This study aims to uncover the relationship between the length of SFA lesions and the outcome of endovascular intervention. Methods: This prospective study included 30 patients with chronic limb-threatening ischemia (CLTI) due to SFA occlusion between February 2022 and August 2022. The patients underwent percutaneous transluminal angioplasty (PTA). Follow-up continued for six months after endovascular revascularization of the limb. Results: The mean age of participants was 59.60±7.70 years. The success rate was 66.7% from the first time with SFA lesions 13.30 ±7.11 cm, 23.3% success after the second trial of re-angioplasty with SFA 22±7.94 cm length of occlusion, and 10% of cases underwent major amputation. Conclusion: The length of SFA occlusion does not significantly affect the initial outcome of endovascular revascularization. However, occlusion length is a good predictor of secondary patency.
