Đánh giá kết quả can thiệp nội mạch điều trị tắc động mạch đùi khoeo mạn tính tại Bệnh viện Chợ Rẫy

Abstract

Introduction: Chronic lower limb arterial occlusion is associated with a 1.05–3.77-fold increased risk of major cardiovascular events compared with individuals without the disease. Its prevalence has been rising in Vietnam. In recent years, endovascular intervention has emerged as a promising therapeutic option, offering favorable outcomes. Objective: To evaluate the outcomes of endovascular interventions for the treatment of chronic femoropopliteal artery occlusion at Cho Ray Hospital during the period 2023–2024. Subject and method: This retrospective case series included patients with chronic femoropopliteal artery occlusion who underwent endovascular revascularization at the Department of Vascular Surgery, Cho Ray Hospital. A total of 52 patients were reviewed. Baseline characteristics, clinical and paraclinical findings, as well as technical details of the procedures, were analyzed. Result: The technical success rate was 98.1%, with one limb (1.9%) experiencing procedural failure. Post-intervention assessment demonstrated palpable femoral pulses in all treated limbs, and popliteal pulses were restored in 98% of cases. Clinical improvement characterized by warmer limbs and reduced pain was observed in 92.3% of patients. The post-procedural ankle-brachial index (ABI) increased significantly from 0.37 pre-intervention to 0.86 post-intervention (p<0.05). Arterial dissection occurred in 26.3% of interventions, and there were four cases of post-procedural complications. Conclusion: Endovascular intervention is an effective and minimally invasive treatment option for chronic femoropopliteal artery occlusion in appropriately selected patients, particularly those at high surgical risk. Treatment strategies should be individualized, and further studies with mid- and long-term follow-up are warranted..
