Case Overview

This case involves a patient who underwent left external iliac artery to superior mesenteric artery bypass surgery. On the second postoperative day (POD #2), the patient experienced increased pain and complications, prompting a CT angiogram of the chest, abdomen, and pelvis.

A testifying diagnostic radiology expert was sought to review and interpret these images.

Questions to the expert and their responses

Q1

How often do you review CT imaging related to superior mesenteric vascular bypass surgery for visualizing the duodenum and other GI structures affected by bypass surgery?

As a board-certified and clinically active diagnostic radiologist with over 20 years of experience, I frequently review various post-operative CTA examinations in my clinical practice. This includes those from active vascular surgery and interventional radiology divisions performing diverse intravascular interventions such as mesenteric (abdominal vessel) bypass, grafting, shunts, and stents.

All abdominal viscera and/or organs, including the duodenum—especially when the superior mesenteric artery is involved—are all visualized/reviewed as part of those exam interpretations where intestinal perforation or ischemia are real concerns

Q2

Have you ever reviewed a similar case? If yes, please elaborate

Yes, I have reviewed similar cases involving post-operative complications following vascular bypass surgery. These cases often involve assessing for potential complications such as intestinal perforation or ischemia. These complications can be identified through careful interpretation of CT angiograms.
