Event or Problem Description
"paraplegia: the relay pro stent graft was implanted to treat a descending aortic aneurysm that was located around the t9-t10 segment of the thoracic spinal cord.The procedure was successfully completed without any endoleak.However, after the procedure, the patient could not move both legs, and paraplegia in the lower half of the body was identified.Since the patient could move both arms and had a sense of touch in the legs, the patient was transferred to the icu for observation.Physician's comment: the procedure was performed under the understanding of both the physician and the patient that implanting a stent graft would cover the adamkiewicz artery, which is located at the distal end of the aortic aneurysm.This event occurred due to the implantation of a stent graft, but not because the stent graft was a relay pro.Physician's comment on the causal relationship: there was no direct causal relationship between the device and this event.(this event would have occurred even if it were not a relay pro.) operation type: tevar.No blood loss.Ancillary device used: 28-n4-32-209-32u (lot: 2410020354).No image available due to hospital policy.No pre-case plan available due to hospital policy.No additional information available due to hospital policy.(tc# (b)(4))" patient outcome: "the patient has sequela.".
