138 Kestle, John R. W.Cerebrospinal fluid shunt technologySince the invention of the first implantable shunt valve by Nulsen and Spitz (12) almost 50 years ago, there has been a remarkable number of ingenious modifications and new designs of shunt equipment to treat pediatric hydrocephalus. These developments were in response to the immediately evident hi...Shunt technology; Valve design2000
139 Kestle, John R. W.Management of shunt infections: a multicenter pilot studyObject. Approximately 10% of cerebrospinal fluid (CSF) shunt operations are associated with infection and require removal or externalization of the shunt, in-hospital treatment with antibiotic agents, and insertion of a new shunt. In a previous survey, the authors identified substantial variation i...Shunt infections; Ventriculoperitoneal shunt; Treatment evaluation2006
