[Invasive intracranial pressure monitoring in posterior cranial fossa after neurosurgery: an exclusive option or a necessity?]

Posterior cranial fossa (PCF) surgery is associated with the risk of increased intracranial pressure ( ICP) under tentorium. The last one can lead to severe brainstem syndromes and postoperative complications. The currently recommended method for ICP control with a supratentorial parenchymal sensor or CSF pressure measurement through an external ventricular drainage is ineffective. Indeed, these methods do not show the true situation in the PCF.
Objective: To determine the feasibility of ICP sensor insertion into cerebellar parenchyma for PCF edema after neurosurgery.
Material and Methods: We retrospectively analyzed literature data (15 references) and 3 patients after ICP sensor insertion into cerebellar parenchyma for ICP control in PCF.
Conclusion: ICP sensor insertion into cerebellar parenchyma is indicated for infratentorial postoperative edema.
