Use of T-Stat to predict colonic ischemia during and after endovascular aneurysm repair: A case report

As surgeons become more aggressive in treating aneurysms with endovascular techniques, traditional surgical principles of preserving internal iliac arteries and the inferior mesenteric artery have been challenged. A case is presented where the T-Stat device (Spectros Corp, Portola Valley, Calif), an optical real-time sensor approved by United States Food and Drug Administration for measuring colon ischemia, was used as an adjunctive measure to assist in the successful endovascular aneurysm repair in a patient at high risk for colon ischemia.
