BACKGROUND
Catheterization of narrow ventricles may prove difficult resulting in misplacement or inefficient trials with potential damage to brain tissue.
MATERIAL AND METHODS
The application of a new module for navigated ventricular catheterization using flexible electromagnetic navigation and a dynamic reference frame is presented.
RESULTS
Navigated catheter placement was successful and accurate in a pilot study. Electromagnetic interferences had to be taken into consideration.
CONCLUSION
Flexible electromagnetic navigation with a dynamic reference frame is a useful tool for catheter placement as it reduces the risk of misplacement or repeated catheterization trials.
