Use of a ventriculosubgaleal shunt in the management of hydrocephalus in children with posterior fossa tumors

We present our experience with the use of ventriculosubgaleal shunting (VSGS) for the management of hydrocephalus associated with posterior fossa tumors in a consecutive series of 63 children. In 42 children, a temporary VSGS was inserted. There were no complications associated with the procedure, and it gave a period of several days in which to improve the general condition of the child, and to perform the necessary imaging studies, without an encumbering external drainage device. In most cases the VSGS could be removed after the posterior fossa surgery, without new general anesthesia. Other advantages and drawbacks of this technique are discussed.
