Subdural Spinal Pressure During Surgery for Intradural Tumours and Surgery for Tethered Cord

To our knowledge studies of subdural spinal pressure during spinal surgery have never been performed. Knowledge of the spinal subdural pressure could be of importance for the surgeon when resecting intradural tumour masses from the spine. Additionally it could be of interest for the team treating the patient with a spinal mass to gain knowledge of the pressure both cranial and caudal to the tumour. In this chapter a study of the measurements of spinal subdural pressure was performed before opening of dura in patients subjected to spinal surgery for intradural tumour or tethered cord. Measurements were performed cranially and caudally to the tumour (if present) and the effect of hyperventilation and positive end-expiratory pressure on spinal subdural pressure studied.
