We evaluated the efficacy of evoked spinal potential (ESP) monitoring during thoracoabdominal aortic replacement to prevent intra-operative spinal ischemia. Nine patients underwent intraoperative ESP monitoring. The ESP was unchanged in 5 patients and decreased in 4 patients. However, ESP recovered in 2 of them by the following techniques: (1) perfusion of intercostal arteries, (2) elevation of distal bypass perfusion pressure, (3) slight hypothermia. Postoperative paraplegia occurred only 1 patient of the 2 whose ESP was not restored. The sensitivity and specificity of the efficacy of ESP monitoring were 100% and 87.5%, respectively. We concluded that ESP is the most useful monitoring for prevention of operative spinal ischemia during thoracoabdominal aortic replacement.
