Abstract
An 82-year-old woman had had bypass surgery for arteriosclerosis obliterans in both legs. We performed a stent graft implantation for an impending rupture of an aneurysm of the descending thoracic aorta complicated with a small abdominal aneurysm. An abdominal thromboembolic aneurysm occurred after the thoracic stent graft implantation due to the detachment of the mural thrombus of the abdominal aneurysm, and therefore we performed an emergency abdominal aorta replacement and thrombectomy in the leg grafts. The leg motor function had been maintained until immediately before the emergency surgery, but a vesicorectal disorder and paraparesis from level 11 of the thoracic spinal cord downward occurred after the emergency surgery. After performing both hyperbaric oxygen (HBO) and physical therapy, the vesicorectal disorder disappeared, and the patient was discharged after she became ambulatory. We believe that paraparesis occurred in this case because of a possible collateral circulation of the lumbar artery to the spinal cord following the thoracic stent graft implantation.
