In this patient, septic emboli from the aortic valve caused an infarction of the artery of Adamkiewicz, which is the largest spinal radicular artery and the only radicular artery to the ASA between T9 and T12 in most patients.
Management of patients undergoing TAAA repair poses challenges like single lung ventilation, massive blood loss-leading to dilutional coagulopathy accompanying large transfusion requirements, and avoidance of paraplegia-that may result as a consequence of prolonged ischemia or resection of the great radicular artery (Artery of Adamkiewicz).
He didn't want to hear, "That sir is clearly the inguinal ligament," for that wouldn't cut it and wouldn't prove that you "know your anatomy." The man wanted to hear, "That sir is clearly Poupart's Ligament." He didn't want to hear that you were confident that you knew he was pointing to "the great cerebral vein," but that you knew it was "the vein of Galen."

The largest of these feeder' vessels, the artery of Adamkiewicz (radicularis magna) supplies the cord in the lumbar region.
