Effect of Evacuation of Cerebral Cysts on Subdural Intracranial Pressure and Cerebral Perfusion Pressure

Patients with intracerebral cysts are frequently presented to the neurosurgical team. Cerebral cysts can either be part of a tumour process or a parasitic disease, such as neurocysticercosis, or present as an arachnoid cyst. The presence of a cerebral cyst can give rise to classic symptoms of increased ICP, and during intracranial surgery a cyst can jeopardize surgical access to deep brain structures and increase the risk of cerebral ischaemia with possible worsening of the outcome. When fluid is removed from a cystic process in the cranial vault the pressure in the cyst will decrease. We have not found any literature addressing this subject. In this chapter unpublished data concerning subdural ICP monitoring in patients with intercerebral cysts and the pressure/volume relationship during emptying are discussed.
