Introduction

Iliac artery aneurysms are uncommon and there is current no protocol for the follow-up.

Aim

To evaluate the progress of the diameter of the iliac arteries by echo-doppler in patients undergoing abdominal aortic aneurysm (AAA) open repair with an aorto-aortic prosthetic graft.

Material and methods

A cross-sectional study of patients undergoing AAA between January 1999 and March 2008, on whom an echo-doppler was performed to assess the diameter of iliac arteries. A total of 45 patients were included. The variables studied were: pre- and post-operative iliac diameter (angio-computerized tomography), vascular risk factors and comorbidities. Student t test, Chi-square test were performed and survival tables constructed.

Results

The mean age was: 69 years (SD 6.8). Follow-up: 4.5 years (1.89). Preoperative mean size of iliac arteries: 13 mm (0.45), follow-up: 17 mm (0.52), p = 0.001. Overall, the diameter increased in 19%iliac arteries during growth monitoring. There was a lower expansion rate in diabetic patients (0%/24%, relative risk [RR] 0.76, 95%confidence interval [CI]: 0.7鈥?.9). We were unable to determine a time/expansion rate correlation. No patient required a repeat operation during the follow-up.

Conclusion

Although our series showed a significant growth, the iliac arteries ultrasound follow-up is not justified, in this context, due to the low/no need for a subsequent surgical procedure.
