Contrast Ultrasound in the Surveillance of Endovascular Abdominal Aortic Aneurysm Repair

The purpose of this study is to support the suspected expectation that Contrast enhanced Ultrasound (CUS) detects all endoleaks that have been detected by Computed Tomography (CT), and also find a number of leaks missed by CT.

The investigators' primary goal is to detect no difference between CT and CUS and provide evidence that CUS is a possible alternative to CT.
