Use of adipose tissue to ease compatibility of a stylet with its sheath during ventriculoperitoneal shunt placement: technical note.

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.
