Abstract

Background Occluding plaques are commonly found in the infrarenal aorta and the iliac artery in patients with peripheral arterial disease (PAD). Aortoiliacocclusive disease (AIOD) occurs commonly in patients with PAD. Methods: This is a prospective study was carried out between 2015 and 2017 in Sina hospital. Patients with occlusion in aortoiliac artery and its branches were included. Stent was placed for patients, if they had any obstruction or stenosis in aortoiliac artery in angiography. Patients were examined in terms of clinical status and ABI calculation and underwent Color Doppler ultrasound of aortoiliac artery to determine patency rate at 1, 3, 12, and 24 months after stent placement. Results: The mean age of patients was 64.60 (±10.41). The main symptoms of the patients were claudication (41.8%), ulcer (27.3%), pain at rest (20%), and gangrene (20%). The lesion was bilateral in 21 patients (38.2%). According to TASC stratification, lesions were of type A in 26 patients (47.3%), type B in 4 patients (7.3%), type C in 5 patients (9.1%), and type D in 20 patients (36.4%). The six-month, one-year, and two-year patency rates were 89.1%, 83.6%, and 72.7%, respectively. The mean annual ABI of patients was 0.79 (±0.11) and two year ABI was 0.68 (±0.1). Conclusion: It seems that stenting and angioplasty are effective in improving patients' conditions and result in a good short and medium-term patency. © 2019 Revista Latinoamericana de Hipertension.
