Kestle, John R. W. | Ventriculoperitoneal shunts in children: indications, equipment and techniques | The decision to implant a ventriculoperitoneal shunt in a child with ventriculomegaly should not be taken lightly. Once a shunt has been implanted, it is very difficult to determine that it is no longer necessary, and therefore the initial decision is very important. Sometimes the need is obvious, s... | | 2008 |
