Official Title: Comparison of Contrast Enhanced Ultrasound and the Gold Standard Computed Tomographic Angiography in Detection of Endoleak Following Endovascular Abdominal Aortic Aneurysm
Brief Summary: The purpose of the study is to compare two different types of imaging techniques to identify endoleaks. Following the endovascular procedure, subjects are seen at one month to have computed tomographic angiography (CTA) to confirm the graft is not leaking (endoleak). CTA is the standard imaging technique used to identify endoleaks. This study will investigate if the image technique color duplex ultrasound with contrast enhanced ultrasound (CEUS) is a good tool to identify endoleaks too.
