In view of the wide range of potential complications, it was decided not to use a shunt before craniotomy. A shunt was inserted only if the CSF pathways remained obstructed after tumor removal. With this regimen, 93% of all patients (100% of the adults and 83% of the children) were shunt-free after the operation, without fatal complications. The infection rate was 4.9%.<\/jats:p>\n<jats:p content-type=\"fine-print\">It was concluded that the severity of symptoms of raised intracranial pressure from hydrocephalus, the intraventricular pressure, and the size or location of the tumor prior to surgery do not have prognostic value as to which patients will require a shunt after surgery.<\/jats:p>","DOI":"10.3171\/jns.1986.65.5.0649","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T16:15:26Z","timestamp":1241799326000},"page":"649-653","source":"Crossref","is-referenced-by-count":52,"title":["Management of obstructive hydrocephalus secondary to posterior fossa tumors by steroids and subcutaneous ventricular catheter reservoir"],"prefix":"10.3171","volume":"65","author":[{"given":"Urs D.","family":"Schmid","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rolf W.","family":"Seiler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"252","DOI":"10.3171\/jns.1963.20.3.0252","article-title":"Ventriculo-atrial shunt in the management of posterior-fossa tumors.
