Although ventriculoperitoneal (V-P) shunt is common as the surgical procedure for hydrocepha-lus, mechanical malfunction and infection are the most significant problems. Despite the current use of variety of mechanical shunting systems, shunt malfunction remains a major problem in pedi-atric neurosurgical practice. Pathological lesions associated with malfunctioning shunts have been studied only infrequently. From April 1980 to December 1987, we experienced 96 cases of V-P shunt in neonates and suckling. The therapeutic results of shunting and causes of initial shunt revi-sion in those cases with nontumoral hydrocephalus were studied. Of 96 cases, which included 55 cases of congenital and 41 cases of acquired hydrocepha-lus, in which a V-P shunt had been performed, those cases with no history of shunt revision or with only elective shunt revision during the 5-year follow-up period were classified as successful shunt.

The 56 of 96 cases (58.3%) successful shunts in-cluded 15 of 24 patients with myelomeningocele, 7 of 10 with encephalocele, 12 of 21 with various types of cerebral anomaly, 12 of 22 with posthemo-rrhagic hydrocephalus and 10 with postmeningitic hydrocephalus. There were 12 successful shunts performed in 27 premature and 44 in 69 mature in-fants. The 40 patients (41.7%) with non-elective shunt revision included 5 with breakdown of the sutured scalp with cerebrospinal fluid leakage, 20 with obstruction of the shunt system (14 ventri-cular side, 6 abdominal side), and 15 with infec-tion. During the 5-year follow-up period 11 died and 85 survived (88.5%), of whom 43 (44.8%) showed normal intellectual development and 42 (43.7%) showed developmental disability.
