Abstract

Backgrounnd: In recent years there has been a shift in the treatment occlusion of aortoiliac and extremity artery from open surgical treatment to endovascular interventions. Endovascular treatment for TASC (Trans-Atlantic Inter-Socity Consensus). Although, a surgical approach continues to be recommende for patiend with low operative risk for complex of TASC class D, but recent studies have revealed endovascular interventions success compared with open reconstruction. Objective: To determine the efficacy, short- term results of percutaneous transluminal angioplasty (PTA) in patients with symptomatic lower extremity artery disease. Methods: From March to December 2020, the cross sectional, descriptive study was carried out on 38 patients with lower limb artery disease, treated by PTA in Vascular Surgery Department of ChoRay Hospital and Cardiovascular-  Thoracic Department of Thong Nhat 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 (79%). The artery treated with angioplasty were aortoiliac (68,4%), femeropopliteal (44,7%) and below-knee artery (42,1%). Balloon angioplasty and stent placement were in 24 patients (63%) and balloon angioplasty in 14 patients (27%). The ankle- brachial index before and after the intervention respectively 0,35 and 0.70 (p<0,001). Overall, the technical successful rate was 97%. The complications included access site hematoma (10%), limb amputation (5,4%), bleeding (1,7%). Conclusion: PTA is a feasible and effective procedure for treatment of  aortoiliac and lower limb artery disease. However, we need to increase the sample size and more study of long term patency of PTA should be conducted.
