Causal Factors of Shunt Revision in Nontumoral Hydrocephalus
Although ventriculoperitoneal shunt is common as the surgical procedures for hydrocephalus, shunt revisions due to their malfunctions and/or complications are frequent. We analysed the causal factors of shunt revision for nontumoral hydrocephalus in our institution. From 1970 to 1985, 73 children with nontumoral and tumoral hydrocephalus received cerebrospinal fluid shunt operation in which 37 cases (50.7%) had shunt revisions. As to nontumoral hydrocephalus, 31 cases (73.8%) of 42 had shunt revisions, of which the total was 63.
