Transient paraplegia after stent grafting of a descending thoracic aortic aneurysm treated with cerebrospinal fluid drainage.

We present a case of descending thoracic aortic aneurysm repair using an endovascular stent graft, complicated by postoperative paraplegia, which was successfully treated by placing a spinal drain. The case highlights the importance of the concept of collateral flow to the spinal cord and of choosing an anesthetic technique that allows immediate postoperative evaluation of lower extremity neurologic function.
