Coincidence of spinal canal stenosis and thoracoabdominal aortic aneurysm.

We report a case in which a thoracoabdominal aneurysm was present in association with previously unknown critical spinal canal stenosis. In spite of using left heart bypass, systemic hypothermia, and controlled cerebrospinal fluid drainage for spinal cord protection, the patient developed paraplegia following aortic aneurysm repair. Computed tomography scan revealed critical stenosis of the spinal canal that was thought to be sufficient to produce spinal cord compression syndromes including paraplegia.
