Results of treatment with ventriculoatrial and ventriculoperitoneal shunt in infantile nontumoral hydrocephalus.
The authors present the results of surgical treatment in 165 children with nontumoral hydrocephalus, treated during a period of 11 years. The minimum period of follow-up was 1 year. The results in the group of children treated with a ventriculoatrial (VA) shunt were compared to those obtained in the group with a ventriculoperitoneal (VP) shunt. 45% of patients with VA shunts had one or more revisions, against 51% of patients with VP shunts. However, the incidence of revisions after 6 months from primary insertion was lower in the VP-shunted children. Most revisions were due to shunt malfunction: obstruction of the ventricular or abdominal catheter was the commonest finding. Among complications, the most serious was constituted by shunt infection (11% of cases). Most infections occurred at less than 2 months from surgery and were caused mainly by Staphylococci. 31% of infected patients died. Other frequent complications were due to shunt tubing lost in abdomen or in the ventricles and subdural hematoma. The overall mortality rate in the whole group was 18%, while the shunt-related mortality rate was 10.9%. Complications were more frequent in the VP-shunted patients, but were less than in VA-shunted patients and accounted for a lower mortality rate. Complications and mortality rate were prevalent in the patients presenting congenital communicating hydrocephalus or myelomeningocele. It is concluded that VP shunt is preferable to VA shunt in the treatment of infantile hydrocephalus.
