Placement of intraventricular catheters using flexible electromagnetic navigation and a dynamic reference frame: a new technique

Abstract

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.
