Prevention of Colon Ischemia During Aortic Aneurysm (AAA) Repair
Prevention of Colon Ischemia During Aortic Aneurysm (AAA) Repair
Patients undergoing surgery on their Aorta can get ischemia, a lack of blood flow, to their
 intestines and colon. This is very serious, as 2 out of 3 patients who have this problem die
 before leaving the hospital. A device developed by Spectros, called T-Stat, is approved by
 the US FDA to detect ischemia, and has been reported to detect ischemia in AAA aneurysm
 surgery and stenting, allowing the surgeon or interventional radiologist to take action
 quickly, while the colon ischemia is still treatable.

 This purpose of this study is to establish how T-Stat can best be used to prevent deaths.
