Purpose: It remains controversial whether to use a tube graft or a bifurcated graft during open abdominal aortic aneurysm (AAA) repair, due to the potential for progression or development of a common iliac artery (CIA) aneurysm. This study evaluated the fate of CIA after tubular AAA repair. Methods: On a retrospective basis, we reviewed 61 patients who underwent open AAA repair with a tube graft, between March 2000 and December 2009. Fifty-seven patients were included in this study; we excluded

CIAs were categorized into 3 groups: normal (≤12 mm), ectasia (range, 13 to 18 mm), and aneurysm (range, 19 to 25 mm). The incidence of CIA aneurysm rupture was investigated, and the expansion rate of CIA was calculated. Results: Mean patient age was 64 years and 73% of patients were male. Preoperatively, 8 patients had 2 normal CIAs, 14 patients had one CIA aneurysm at least, 27 patients had one CIA ectasia, and 8 patients were unknown. There was a mean follow-up of 51 months; no deaths were caused by rupture of CIA aneurysm, and no patient underwent invasive treatment for a CIA aneurysm. The mean follow-up for 24 patients with 48 CIAs was 45 months. The mean expansion rate of CIA was 0.5 mm/y. Conclusion: AAA repair using a tube graft was a safe and durable procedure. However, a bifurcated graft should be considered when patients are young and there is the expectation of a long life expectancy is anticipated allowing for a CIA expansion rate of 0.5 mm/y.
