Intraoperatlve Spinal Cord Monitoring: EYoked Potentials and Cerebrospinal Fluid Oxygenation

摘要

Surgical procedures that involve occlusion of the spinal cord feeding arteries, application of corrective forces to the spine, invasion of the cord, or local osteotomy carry the risk of iatrogenic spinal cord injury. Current reports indicate that the incidence of paraplegia after aortic surgery ranges between less than 0.1% after repair of aortic coarctation and 15% after resection of thora-coabdominal aneurysms [1-3]. The incidence of neurological deficits after correction of kyphosis and congenital scoliosis varies between 1 % and 2% [4]. Definite numbers of spinal cord injury after spinal neurosurgery are lacking, although an Increasing use of spinal cord monitoring is reported in these procedures [5, 6].
