✓ Direct therapeutic drainage and intracranial pressure monitoring from the posterior fossa has never been accepted in neurosurgical practice. Potential complications including cerebrospinal fluid leak, cranial nerve palsies, and brain-stem irritation have been a major deterrent. The authors placed a catheter for pressure monitoring in the posterior fossa of 20 patients in the course of posterior fossa surgery: 14 patients with acoustic schwannomas, four with posterior fossa meningiomas, one with cerebellar hemangioblastoma, and one with a solitary cerebellar metastatic lesion. A Richmond bolt was also placed in the frontal area. Continuous monitoring of the supratentorial and infratentorial compartments was performed for 48 hours. During the first 12 hours the posterior fossa pressure was 50% greater than that of the supratentorial space in all patients (p < 0.01). Over the next 12 hours the supratentorial pressure was 10% to 15% higher than the posterior fossa pressures in all patients, and by 48 hours of monitoring the pressures had equilibrated. There was no mortality or morbidity referable to insertion of the posterior fossa catheter. The conclusions drawn from this study are that: 1) direct monitoring and drainage of the posterior fossa is safe and effective; and 2) within the early postoperative period, the supratentorial pressures failed to reflect what is taking place within the posterior fossa. The implications and advantages of direct posterior fossa monitoring in the postoperative patient are discussed.

AbstractIntracranial pressure monitoring has become critical for the adequate management of patients with severe head injury in recent years. Several other recommendations for intracranial pressure monitoring have also been described, specially for patients with subarachnoid hemorrhage with ventricular enlargement, and spontaneous intracerebral hematomas. The immediate postoperative period of elective surgeries that require brain retraction is another instance where intracranial pressure monitoring could provide useful informations to optimize outcome. Expensive methods make it almost prohibitive to smaller centers in our Country.We describe our protocol of routine intracranial pressure monitoring using an intraventricular catheter connected to an external strain gauge transducer adapted to an ordinary invasive pressure monitor, in a countryside university hospital, and analyze the data of intracranial pressure and cerebral perfusion pressure obtained with regards to outcome and also investigate the more common complications of the method.We conclude that intracranial pressure monitoring could be safely applied at a low cost to improve the management of those patients.

✓ Recordings from two different types of subdural pressure monitor with simultaneous intraventricular pressure (IVP) tracings are compared in 20 head-injured patients. In the first 10 patients a fluid-filled catheter was placed subdurally and connected to an external transducer, and in the second 10 the Gaeltec model ICT/b solid state miniature transducer was used. The latter system has the advantage that both zero and calibration checks can be carried out after insertion. Only 44% of the fluid-filled catheter readings corresponded with IVP in series of 10-mm Hg ranges, while 53% of readings were lower; this tendency was more marked at higher pressures. With the Gaeltec transducer, 72% of subdural pressure readings corresponded with IVP, while only 9% were lower and 19% were higher than IVP. The differences may have been due to technical causes or to true pressure differentials. The subdural catheter appears too unreliable for routine clinical use, but the Gaeltec transducer may be a satisfactory alternative to ventricular pressure monitoring.

✓ Computerized tomography scanning has shown that acute traumatic intracranial hematomas are more common than was previously realized, but whether all hematomas must be removed remains controversial. About half of this series of 26 patients who were not clinically deteriorating and who were initially managed without operation had to undergo hematoma removal because they subsequently deteriorated. Features present at the time of diagnosis (age, type and site of hematoma, presence of focal signs, level of responsiveness, and degree of midline shift) were not helpful in predicting that operation would be needed. The only discriminatory factor was the level of intracranial pressure (ICP). All the patients with ICP greater than 30 mm Hg deteriorated and required operation, but only one patient whose ICP was less than 20 mm Hg deteriorated. Half the patients with ICP between 20 and 30 mm Hg did not require an operation. Intracranial pressure monitoring can, therefore, be useful in managing patients with an occult intracranial hematoma.

✓ The relationship between intracranial pressure (ICP) and outcome was studied in 10 adults with encephalitis. Eight had biopsy-proven herpes simplex encephalitis, one had acute hemorrhagic leukoencephalitis, and in one case the cause of encephalitis was unknown. Monitoring of ICP was instituted because of clinical deterioration or computerized tomography evidence of brain swelling, and was begun a mean of 7 days after the orlset of symptoms and continued for a mean of 9 days. All five survivors, but only one of the five fatalities, had an initial ICP of less than 12 mm Hg (p < 0.05). Four patients with a mean daily ICP of less than 20 mm Hg survived, whereas five of six patients with higher ICP's died (p < 0.05). Peak ICP did not occur until the 12th day of illness on average. The Glasgow Coma Scale score at the time the ICP monitor was inserted did not correlate with outcome. Intracranial pressure monitoring in severe encephalitis may be a useful adjunct for therapy and an indicator of prognosis.

AbstractIntracranial pressure monitoring has become routine in the management of severe head injuries. We describe an unusual complication secondary to intracranial pressure monitoring with subdural cup catheter. A 35 year-old man was admitted to the Neurosurgery Department following blunt head trauma. He underwent insertion of subdural cup catheter for monitoring of intracranial pressure. A progress computed tomography scan of the brain revealed tension pneumocephalus. As far as the authors are aware, this is the first reported case of tension pneumocephalus resulting from insertion of a subdural intracranial pressure monitor.

✓ A comparison of intraventricular pressure (IVP) and extradural pressure (EDP) was carried out in 17 patients being investigated for normal-pressure hydrocephalus, and in six patients with acutely raised intracranial pressure following events such as head injury or intracerebral hematoma. Extradural pressure was measured using the CardioSearch monitor. There was a reasonably good correlation between EDP and IVP in the chronic stable group with pressures up to 25 mm Hg. In the acute group there was no predictable relationship between EDP and IVP, and during a 24-hour period the pressures could vary by as much as 30 mm Hg. Subdural pressure, measured with the same instruments, was compared to IVP in both acute and stable situations in eight other patients: there was a close and constant correlation between pressures in these two spaces. The authors conclude that misleading information may be obtained from EDP monitoring, and erroneous management decisions may result from dependence on such a technique. Possible explanations for this are discussed.

✓ A prospective series of 100 consecutive severe head injuries is presented. There were 34 deaths. Intracranial pressure (ICP) was not monitored in this series, and it is suggested that the outcome compares favorably with series in which ICP monitoring was performed. Early evacuation of life-threatening intracranial hematoma and airway control remain essentials of treatment of severe head injury.
