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.

  • Endograft Implantation to Repair Abdominal Aortic Aneurysm

PROCEDURE

Contrast Enhanced Ultrasound (Contrast Agent: OptisonTM)

The contrast agent will be prepared using a single, 3 mL vial of Optison and 57 mL saline combined in a sterile syringe. Contrast will be set to deliver a continuous infusion at 4 mL/min, via peripheral access. In the event that the above description of the administration of Optison is not adequate for lumen flow contrast enhancement the PI or Co-I will direct the study team to proceed to the secondary administration procedure. This will be done by the following: 0.5 mL of Optison will be injected into a peripheral vein. This may be repeated for further contrast enhancement as needed. The maximum total doses should not exceed 5.0 mL in any 10 minute period nor exceed 8.7 mL in any one patient study. We will follow the insert package dose. We will not not exceed 5.0 or 10 minutes or 8.7ml per patient (this will include the 0.5mL for initial). Therefore, no more that 8.2mL will given in this second administration procedure.
