✦ Synopsis

Shunt function and complications in different etiologies of childhood hydrocephalus were studied in a series of 306 patients involving 1102 shunt operations. Shunts in patients with hydrocephalus caused by neoplasms proved to be most prone to shunt complications. The patency time for shunts in these patients was significantly shorter than for shunts in other patient categories [Standard number of deviations (SND) 5.9; P less than 0.001, Meyer-Kaplan life table analysis]. When the two main groups of infantile hydrocephalus-congenital obstructive hydrocephalus and hydrocephalus caused by perinatal intracerebral hemorrhage-were compared, the latter group proved to be significantly more prone to shunt infections (P less than 0.01), with an infection rate of 17.8% compared with 8.9% for the former group. The importance of this fact is stressed by the observation that these patients appear to constitute an increasing percentage of hydrocephalic patients. According to the present study, patients with congenital intracranial cysts and hydrocephalus are less prone to shunt complications, i.e., the infection rate is 6.8%, which is significantly less than that of patients with other types of hydrocephalus (P less than 0.01; chi-square test).
