A 74-year-old man with a 50-mm infrarenal aortic aneurysm was performed endovascular aortic repair (EVAR) under local anesthesia. On EVAR, there were neither significant difficulties nor unstable circulatory dynamics during the procedure. After the procedure, he developed paraplegia immediately. His paraplegia improved by cerebrospinal fluid drainage, steroid administration, and arterial pressure augmentation. At present, he can ambulate with walker after re-habilitation for 3 months. Postoperative magnetic resonance imaging (MRI) showed spinal cord ischemia.
