Methods: Medical records of 23 patients with IIAA with an aneurysm diameter greater than 3.5 cm who underwent treatment between January 2004 and July 2012 in our clinic were retrospectively analyzed. The patient records during hospital stay and follow-up were evaluated. Parameters including demographic data of the patients, localization of the aneurysms, the type of procedure, the length of intensive care unit (ICU) and hospital stay were recorded. Thirteen patients (12 males, 1 female; mean age 69.3±11 years; range 57 to 80 years) were treated with endovascular stent grafts repair (EVAR), whereas 10 patients (9 males, 1 female; mean age 71.4±9 years; range 63 to 82 years) underwent open surgery. Six out of 13 EVAR patients and three out of 10 open surgery patients underwent emergent operation due to ruptured IIAA.

Results: The mean length of hospital stay and ICU stay in EVAR group were 1.9 and 0.7 days, respectively, while in surgery group these were 10.9 and 7.2 days, respectively. Technical success and postoperative early patency rates were 100% in both groups. Perioperative and in-hospital mortality rate were 0% in EVAR group; however one patient (10%) died due to respiratory failure on postoperative 56^th day in ICU.

Conclusion: According to our study results, we conclude that EVAR can be performed with a lower morbidity and mortality rate compared to open surgery in the management of iliac artery aneurysms, which is consistent with the literature.
