Gliederung

Text

Objective

In conventional methods, the implantation of catheters and electrodes via stereotactic tube guides requires that the implant has a great length and passes entirely through the tube guide. Implants such as microdialysis catheters do not correspond to these conditions due to their short length and their proximal connection part which is too thick to pass through a conventional stereotactic tube guide. We describe a technique which allows placing these kinds of implants using stereotaxy.

Methods

The stereotactic approach is planned on a neuronavigation station (STP4 of Leibinger, Stealth Station of Medronic). A tube guide (e.g. intravenous catheter), shorter than the implant, is placed under stereotaxy on the approach with the help of a long stereotactic stylet and fixed to the skull (e.g. with surgical cement). The stylet is pulled out. The implant is then advanced towards the target via the tube guide respecting the measured length of the proximal tube guide aperture to the target. The implant is fixed to the tube guide and to the skin. The correct position of the implant can be checked by CT-scan or MR 3D-imaging integrated in the neuronavigation station. At the moment of the implant’s ablation, the tube guide is pulled out at the same time.

Conclusions

The described technique allows the stereotactical placement of implants that can not be introduced by conventional tube guide methods.
