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.<\/jats:p>\n<jats:p content-type=\"fine-print\">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 &lt; 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.<\/jats:p>\n<jats:p content-type=\"fine-print\">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.<\/jats:p>","DOI":"10.3171\/jns.1989.71.4.0503","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T16:23:22Z","timestamp":1241799802000},"page":"503-505","source":"Crossref","is-referenced-by-count":42,"title":["Intracranial pressure monitoring in the posterior fossa: a preliminary report"],"prefix":"10.3171","volume":"71","author":[{"given":"Robert H.","family":"Rosenwasser","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurence I.","family":"Kleiner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph P.","family":"Krzeminski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William A.","family":"Buchheit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurological Surgery","first-page":"1938","article-title":"Diagnosis and treatment of head injury in adults","volume":"4","author":"Becker","year":"1982"},{"key":"b2","series-title":"Postoperative Complications of Intracranial Neurological Surgery.","first-page":"29","author":"Horwitz","year":"1982"},{"key":"b3","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"145","DOI":"10.3171\/jns.1970.33.2.0145","article-title":"Continuous simultaneous monitoring of the intraventricular and cervical subarachnoid cerebrospinal fluid pressure to indicate development of cerebral or tonsillar herniation.","volume":"33","author":"Kaufmann","year":"1970"},{"key":"b4","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"989","DOI":"10.3171\/jns.1964.21.11.0989","article-title":"Transmission of increased intracranial pressure.
