[Show abstract][Hide abstract] ABSTRACT: The study protocol was approved by the ethics committees of the Queen Elizabeth Hospital and Royal Adelaide Hospital. All patients were provided with detailed information regarding the study, and informed consent was obtained. Patients with an aortic aneurysm of 5.5 cm or more were eligible for the study. Preoperative moderate or severe renal impairment (serum creatinine >0.210 mmol/L) and administration of corticosteroid medications within 6 months before surgery were exclusion criteria. Allocation to open or endovascular methods of repair was not randomized but was determined by anatomic suitability and surgeon preference. The patients in the open group underwent traditional transperitoneal repair of the infrarenal AAA with either tube or bifurcated grafting, as judged by the operating surgeon. The endovascular group underwent placement of a Zenith (Cook Inc, Bloomington, Ind) endograft or Excluder (WL Gore & Associates, Flagstaff, Ariz) via bilateral groin incisions.
