Use of Indocyanine Green During Repair of a Superior Mesenteric Artery Aneurysm.

Superior mesenteric artery (SMA) aneurysms are rare and associated with a high risk of rupture, with resultant significant morbidity and mortality. During open operative repair of a superior mesenteric artery aneurysm, perfusion of the involved small bowel must be evaluated when determining need for and/or extent of vascular reconstruction. We present a case of a 51-year-old woman who underwent open repair of a non-ruptured superior mesenteric artery aneurysm with ligation and excision, in whom no revascularization was determined to be needed and the involved small bowel was able to be preserved, with intraoperative evaluation of perfusion using indocyanine green (ICG) fluorescence imaging, as an adjunct to more traditional methods of perfusion assessment.
