Objective: Objective of the study is the evaluation of feasibility, safety and reliability of posterior fossa intracranial pressure (PFP) monitoring in patients with hemorrhagic-traumatic primary lesions of the posterior fossa. Evaluation of supratentorial-infratentorial pressure gradient and preliminary data analysis in order to suggest clinical usefulness of PFP monitoring.

12 patients were admitted to ICU for posterior fossa SAH (3 cases), cerebellar hemorrhage (6 cases) or cerebellar traumatic contusion (3 cases). Mean GCS at admission was 6. All patients presented triventricular hydrocephalus on admission CT scan. Then a ventricular drain associated with straingauge type microsensor was emergently placed in the operating room to allow deliquoration and ICP monitoring. A perenchimal straingauge type microsensor was placed into posterior fossa (entry point 3 cm behind mastoidal incisura and 2,5 cm below the superior nucal line). Sensor positioning was verified by CT scan. Al the monitoring data were recorded once at hour.

No complications related to sensor positioning into the posterior fossa were detected by CT scan. 5 patients died, 3 presented good recovery and 4 moderate disability. In all patients a statistically significant pressure gradient between posterior fossa (18,3 mmHg ±14,3) and supratentorial compartment (12,2 mmHg ±13,9) was verified (wilcoxon sign rank test).

PFP monitoring is an easy and safe procedure. Correct evaluation of PFP should allow the optimization of perfusion pressure of the posterior fossa (PFPP) in patients with primary lesions of the posterior fossa. Moreover PFP itself and supratentorial-infratentorial pressure gradient should be elements for patients management and for evaluation of therapeutical options (surgical decompression, osmotics agents). Largest number of cases and multicentrical studies will be necessary for a more accurate evaluation of clinical usefulness of monitoring data.
