Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: The purpose of this study is to evaluate the location within the renal artery of maximal angular displacement before and after fenestrated endovascular aortic repair (FEVAR) using CT with end-inspiration and end-expiration CT images before and after repair. Then, the renal artery segment with maximal angular displacement on each will be located and any changes described.

Participants: There will be 30 subjects recruited from UNC Hospitals.

Procedures (methods): For this study, patients will receive an additional CT sequence (end-expiration CT), which will be compared with the standard of care end-inspiration CT to calculate angular displacement and the distance from the aorta.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators would like to evaluate the location within the renal artery of maximal angular displacement before and after fenestrated endovascular aortic repair (FEVAR) using CT with end-inspiration and end-expiration CT images before and after repair. The investigators would then locate the renal artery segment with maximal angular displacement on each and describe any changes. Because these patients would be getting pre and post-surgical CTs as part of standard of care, there would be no added charge to obtain the information for the study. There would be, however, minimal increased radiation exposure resulting from the extra scan being performed during end-expiration and the patients would have to consent to the slight added risk to participate.
