A New, Curved Catheter for Ventriculoperitoneal Shunting: Technical note
In 1955, Scott et al. first reported the clinical application of the ventriculoperitoneal (VP) shunt. Since then, several problems and complications associated with it have been reported. The commonest events necessitating shunt revision are catheter obstruction and infection. Frequent causes of obstruction include penetration of the choroid plexus, brain debris, and fibrous tissue. In such cases, the tip of the conventional, straight ventricular catheter often perforates the septum pellucidum and enters the contralateral ventricle, where it penetrates the choroid plexus, resulting in malfunction. To avoid this complication, we designed a curved catheter (manufactured by Dow Corning, K. K., Kanagawa, Japan) that can be advanced into the anterior horn of the lateral ventricle.
