Background:
When placing a ventriculoperitoneal shunt in adults, we have found it is often difficult to insert or remove the stylet of the shunt passer. Saline fails to provide sufficient lubrication, and the biocompatibility of mineral oil has not been substantiated.
Objective:
The authors describe a novel technique to ameliorate this problem.
Clinical Presentation:
Ventriculoperitoneal shunt placement is a common procedure within neurosurgery. This technique is conceivably applicable to all patients requiring diversion of cerebrospinal fluid.
Intervention And Technique:
A small amount of adipose tissue is harvested from the incision in the abdominal wall. The adipose tissue is rubbed along the stylet before it is inserted into the sheath.
Conclusion:
Autologous adipose tissue can be used safely and effectively as a lubricant for ventriculoperitoneal shunt passers to facilitate the compatibility of a stylet with its sheath. The technique thereby eases the process of passing distal shunt tubing.
