Conditions

Abdominal Aortic Aneurysm

Brief summary

Blood supply to the sigmoid colon during open abdominal aortic aneurysm (AAA) repair is at risk. Ischemia of the sigmoid colon after AAA repair is potentially devastative. No reliable measures to prevent it are available and the underlying mechanisms are poorly understood. The aim of this study is to describe intraoperative perfusion patterns of the sigmoid colon during open AAA repair and their potential impact on postoperative outcome.
