Description of intervention(s) / exposure
Prospective double blind study

Particapants undergo computed tomography and two duplex ultrasound scans on the same day
The study involves direct comparison between the computed tomography and duplex findings in regard to maximum aneurysm diameter correlation, edoleak detection and classification and graft patency. The study began in Feburary 2005 for 1 year duration

Summary
Brief summary
Endoluminal repair of abdominal aortic aneurysm (enlargement of the main artery) is a relatively new procedure whic requires long term follow-up. This is usually done with computed tomography which has the disadvantages of repeated dose of contrast agents and radiation. We believe ultrasound can be used to follow-up patients after endoluminal repair with out any harmful effects.
