Expanding ventricular shunts for hydrocephalus in infancy and childhood

Expanding, adult-length catheters to accommodate continuing somatic growth have been implanted in the course of shunts, either to the heart or peritoneum, in 12 hydrocephalic infants and young children. Three of four patients with direct cardiac shunts are doing well 22, 28 and 30 months following primary shunt operations, and five of eight patients with ventriculo-peritoneal shunts are progressing favourably four to 10 months after shunt placement. While no claims can be made for long-term benefits, the preliminary results of these procedures are encouraging.
