Abstract
An increasing number of patients with abdominal aortic aneurysms are treated using endovascular rather than open surgical techniques. The Vascular Surgery Center, P. Stradins Clinical University Hospital, has the largest worldwide experience using a new type of endoprosthesis, which fills and anchors the device in the aneurysm sac. Within the framework of a clinical trial, the quality-of-life evaluation of patients treated using this type of device was carried out. A cohort study was conducted from 2008 to 2011 comparing the quality of life (QOL) of patients after abdominal aortic aneurysm repair with either the new endovascular treatment method (EVAR) or open surgery (OS). Each group comprised 20 patients, and the quality-of life-evaluation was performed using the SF-36 questionnaire before operation, 1 month after operation, and 1 year after operation. One month after operation, an improved QOL was documented in the EVAR group (47 [SD, 3] in the EVAR group vs. 38 [SD, 3] in the OS group, P<0.001). One year after operation, a significant improvement in QOL persisted although the difference between the groups diminished (48 [SD, 4] in the EVAR group vs. 42 [SD, 3] in the OS group, P<0.001). The patients with abdominal aortic aneurysms who underwent EVAR using the new sac-anchoring endoprosthesis have improved health-related quality of life compared to the patients undergoing open surgical repair. The improvement in quality of life remained slightly better in the EVAR group 1 year after operation.

Summary
The reported prevalence of abdominal aortic aneurysm (AAA) among people aged 65 to 80 years is 5.2%. Open surgery is a proven, effective method of treatment with a perioperative mortality rate of 1.2%–5% It is involves major surgical trauma with significant morbidity and significant risk of a number of complications (in up to 15% of cases). Even though endovascular treatment is less invasive than open repair and patients have fewer traumas during the operation and they recover more quickly during the early postoperative period, the impact of other factors on patients’ quality of life has not been clear yet. Such factors include the need for routine postprocedure
