ABSTRACT
PURPOSE: The purpose of this study was determination of the expansion rates relative to the size of the common iliac artery (CIA) after elective placement of a straight aortic tube graft for an infrarenal abdominal aortic aneurysm (AAA). METHODS: Between January 1993 and December 1997, 74 men (mean age, 69 years) with AAA underwent surgical repair with a straight tube graft. All patients underwent preoperative and postoperative computed tomography (CT) scans. The mean follow-up period was 68.3 months. The preoperative CT scan revealed a dilatation of at least one of the two CIAs in 32 patients (43.2%; group A). Within this group, the CIA was ectatic (12 mm < diameter < 18 mm) in 13 patients (subgroup A1) and aneurysmal (diameter >/=18 mm) in 19 patients (subgroup A2). The diameters of both CIAs were normal (diameter
