An 83-year-old man with a 50mm infrarenal aortic aneurysm underwent an endovascular aortic repair(EVAR)under general anesthesia. The stent graft was positioned below the renal artery. During EVAR, the mean arterial pressure was maintained over 60mmHg and the activated whole blood clotting time was maintained over 240s. No neurological abnormalities were observed after extubation in the operating room, but paraplegia developed 5 h after surgery. Emergency cerebrospinal fluid drainage, steroid administration and arterial pressure augmentation were ineffective. Paraplegia after EVAR is rare;however, physicians should be aware of this possible complication.
