In traumatic brain injury, subarachnoid blood obstructs the flow of CSF in basal cisterns which in turn locks up CSF in Virchow-Robin Space. This sudden reaction produces excessive fluid efflux in to the interstitial tissues (extracellular space), thus producing increased brain edema and intracranial pressure (ICP). Basal cisternostomy involves microsurgical opening of the cisterns by opening the subarachnoid layers and Liliequist membrane, thus letting out the locked up CSF. This procedure instantneously reduces the ICP and also relaxes the brain parenchyma, thus reducing the secondary insult to cerebral cells.
