Umbilical fistula as a complication of ventriculo-peritoneal shunt

Two cases of CSF umbilical fistula in children with ventriculo-peritoneal shunt are reported. In the first at exploratory laparotomy there was a persistent umbilical vein and in the second a diffuse perivisceritis. Only three cases of this complication of ventriculo-peritoneal shunt have been reported in the literature.
