Short-term outcomes of endovascular therapy for chronic lower extremity arterial disease

Abstract

Background: Chronic lower extremity arterial disease, mostly caused by atherosclerotic etiology, has been increasing in recent years. Currently, there has been a shift in the treatment chronic lower extremity arterial disease from open surgical treatment to endovascular intervention. According to the TASC classification, surgical treatment is preferred for patients with complex lesions of TASC C, D but recent studies have shown that endovascular intervention has had good results for high-grade lesions.
 Objective: To determine the efficacy, short-term results of endovascular intervention in patients with symptomatic lower extremity artery disease
 Methods: From January to December 2021, the cross sectional, descriptive study was carried out on 38 patients with lower limb artery disease, treated by endovascular intervetion in Interventional Department, Hanoi Heart hospital. All patients were evaluated by clinical symptoms, ankle- brachial index and lesion characteristic before and after the intervention to determine the initial success
 Results: Majority of lesions belong to TASC II C and D (78,9%). Injured arteries can be isolated in the aortoiliac (21,1%), femoropopliteal (21,1%), below-knee artery (21,1%) or combine aortoiliac and femoropopliteal (10,5%), femoropopliteal and BTK (15,8%). The ankle- brachial index before and after the intervention respectively 0,57 and 0.83 (p<0,001). The technical successful rate was 94,7%. Balloon angioplasty and stent placement were in 21 patients (55,3%) and balloon angioplasty in 17 patients (44,7%). Post-procedural complications included stent thrombosis (2.6%), amputation (2.6%), pseudoaneurysm at the puncture site (2.6%).
 Conclusion: Endovascular intervention is a safe, effective, minimally invasive method in the treatment of chronic lower extremity arterial disease
