[Intraoperative sonographic diagnosis of the ventricular position of shunt systems in infants with hydrocephalus].

Intraoperative ultrasound is performed in hydrocephalic newborn who were undergoing placement of a ventriculoperitoneal shunt. It is possible to show intraoperatively the tip of the ventriculoperitoneal shunt tube. By this method the optimal positioning of shunt tube is assured and the postoperative complication rate may be reduced. The use of this method is demonstrated by case reports.
