Abstract

Background: Lower extremity artery disease is a severe condition and poses challenges in treatment. This study aimed to: evaluate the clinical and subclinical characteristics of below-the-knee artetiris desease in elderly patients and assess the efficacy and safety of endovascular intervention treatment. Materials and method: A retrospective case series study of elderly patients with below-the-knee artery disease who underwent endovascular intervnetion from 12/2022 to 04/2024 at Thong Nhat Hospital. Result: A total of 83 cases, male/female ratio of 2:1. Patients were divided into 2 groups: ulcer-tissue loss (32.5%) and non-ulcer-tissue loss (67.5%). TASC-II B was 33,8%. Endovascular intervention time was 65.8 minutes. Technical success rates were 93.9% (after intervention), 83.1% (06 months). Good clinical outcomes were 73.5% (after intervention), 63.8% (06 months). Complications: 03 cases of infection, 01 case of bleeding, 03 cases of pseudoaneurysms, 08 cases of progressive renal failure, 01 case of amputation, and 01 death due to multiple comorbidities. Conclusion: below-the-knee arterial desease in elderly patients is a severe condition often associated with multiple comorbidities. Endovascular intervention demonstrated favorable results.
