Neurological complications following aortic surgery

A case of spinal cord ischaemia developing in a man aged 70 years following thoracic aortic surgery is reported. In contrast, two further cases associated with surgery for resection of coarctation of the aorta are described, in a younger age group. A review of the literature reveals a small but increasing incidence of reports of spinal cord complications following varied types of surgery; the anatomy of the blood supply to the spinal cord is reviewed and recommendations are made for the appropriate conduct of anaesthesia and surgery in patients at risk.
