The management of large bilateral internal iliac artery aneurysms using the T-Stat Colon Oximeter

Internal iliac artery (IIA) aneurysms are rare and the repair of these aneurysms is associated with high risk of morbidity and mortality. Bilateral IIA aneurysms add an increased concern for ischemic complications. A case is presented where the use of a Food and Drug Administration-approved device, the T-Stat Colon Oximeter, allowed additional information for the safe and successful hybrid exclusion of bilateral large IIA aneurysms. A staged approach with the use of Amplatzer plugs, Powerlink device, Zenith iliac plug, and a femoral-femoral bypass allowed successful exclusion of the IIA aneurysms. The immediate and 18-month follow-up of the IIA aneurysms are reported.
