Physician-Modified Reversed Iliac Branch Device to Prevent Spinal Cord Ischemia in an Urgent Branched Endovascular Aortic Repair.

Intraoperative modification of an iliac branch device during an urgent branched endovascular aortic repair enabled preservation of a potentially critical segmental artery, thus reducing the risk of spinal cord ischemia. This adaptive interventional technique may also offer a strategy for preserving other anatomically significant vessels, such as accessory renal arteries, during complex aortic reconstructions in urgent settings.
