Recurrent spinal cord ischemia after endovascular stent grafting for chronic traumatic aneurysm of the aortic isthmus.

This report describes the development of recurrent spinal cord ischemia in a patient after insertion of a stent graft into the upper segment of the descending thoracic aorta for the treatment of a chronic traumatic aneurysm of the aortic isthmus. Intraoperatively, the stent covered the ostium of the left T7 artery, which was shown to give rise to a middle dorsal artery by postoperative spinal cord arteriography.
