Abstract
- 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 4 cases in which the patients died in-hospital. Of those enrolled, 24 patients underwent follow-up computed tomography at least 1-year after surgery. CIAs were categorized into 3 groups: normal (< or =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.
