Abstract

Objective: To evaluate the mid-term limb salvage outcomes in patients with below-the-knee arterial stenosis and occlusion treated with endovascular balloon angioplasty at the University Medical Center Ho Chi Minh City. Methods: A prospective observational cohort study was conducted on 127 patients with below-the-knee arterial stenosis and occlusion who underwent balloon angioplasty at the University Medical Center Ho Chi Minh City between January 2022 and July 2024. Results: The mid-term limb salvage rate remained comparable to the early post-intervention period (85%). Mid-term mortality occurred in 4.7% of patients, of which 83.3% were related to respiratory complications and 16.7% to septic shock (secondary to an anorectal fistula infection, unrelated to the intervention). The reintervention rate was 37.8%. Conclusion: Mid-term outcomes demonstrated a high limb salvage rate, which remained stable compared to the early post-intervention period. The mortality rate was low and mainly associated with respiratory complications, without direct relation to the procedure. However, the considerable reintervention rate highlights the importance of regular follow-up and early detection of restenosis to ensure long-term treatment success.
