Abstract

Introduction: Abdominal aortic aneurysms (AAA) was the local dilatation of aortic artery with a diameter larger than the diameter of the normal abdominal aortic segment by 1.5 times. The aneurysmal sac can grow over time and progress to rupture with a high risk of death unless properly treated. Endovascular aneurysm repair (EVAR) was widely applied with the safety and effectiveness in the treatment of AAA. Objective: This study was conducted to investigate the clinical and subclinical characteristics and to evaluate the early results of endovascular repair in the treatment of infrarenal AAA. Material and method: This is a prospective study. All cases of infrarenal AAA were treated by EVAR at Vascular surgery Department, Cho Ray Hospital from May-2012 to August-2017. Results: A total of 95 cases (71 males and 24 females) were eligible for inclusion in the study. The mean age was 73,8 ± 17,6. The most common clinical symptom was abdominal pain (62,1%). Hypertension, smoking and lipid disorders were considered the common risk factors and comorbidities. The majority of aneurysms were fusiform with the mean diameter of 59.9 ± 15.1mm. EVAR was performed with the technical success rate of 98,9%. The most complication was local hematoma (11,6%). The early mortality rate of 1.1% occurred in 1 patient with myocardial infarction in the postoperative period. Conclusion: AAA is a dangerous disease and common in elderly people.  EVAR is a minimally invasive method showing the safe and efficiency in the treatment of infrarenal AAA
