title: Evoked spinal cord potential monitoring reveals peroneal nerve ischemia during thoracoabdominal repair: a case report.
abstract: An 82-year-old man underwent thoracoabdominal aortic replacement under cardiopulmonary bypass with left femoral artery cannulation. Lumber descending evoked spinal cord potentials and segmental evoked spinal cord potentials were monitored simultaneously for detecting spinal cord damage. When the cardiopulmonary bypass was terminated, a peripheral nerve ischemia pattern was evident. Left peroneal nerve paralysis was present at emergence from anesthesia. This monitoring system revealed that peroneal nerve paralysis can occur due to leg ischemia caused by femoral artery cannulation. This is, to our knowledge, the first report that segmental evoked spinal cord potential monitoring reveals peroneal nerve ischemia during thoracoabdominal surgery.
