Subdural Intracranial Pressure, Cerebral Haemodynamics, Dural Tension and Degree of Swelling After Opening of Dura in Patients with Infratentorial Tumours

The prone position is often recommended for surgery in patients with space-occupying lesions localized in the occipital region or the posterior fossa. Compared to the supratentorial compartment, space-occupying lesions in the smaller infratentorial compartment may have a different influence on subdural ICP and the tendency to brain swelling. In addition, positioning the patient in either the supine, lateral or prone position may influence the level of subdural ICP. In this chapter we present two studies. In the first study we present data concerning the relationship between the ICP and the degree of brain swelling in patients undergoing infratentorial surgery. In the second study we focus on whether placing the patient in the supine, lateral or prone position has any influence on subdural ICP during surgery for occipital tumours.
