ACCURACY OF VENTRICULOSTOMY CATHETER PLACEMENT USING A HEAD- AND HAND-TRACKED HIGH-RESOLUTION VIRTUAL REALITY SIMULATOR WITH HAPTIC FEEDBACK

OBJECTIVE:

The purpose of this study was to evaluate the accuracy of ventriculostomy catheter placement on a head- and hand-tracked high-resolution and high-performance virtual reality and haptic technology workstation.

METHODS:

Seventy-eight fellows and residents performed simulated ventriculostomy catheter placement on an ImmersiveTouch system. The virtual catheter was placed into a virtual patient's head derived from a computed tomography data set. Participants were allowed one attempt each. The distance from the tip of the catheter to the Monro foramen was measured.

RESULTS:

The mean distance (+/- standard deviation) from the final position of the catheter tip to the Monro foramen was 16.09 mm (+/- 7.85 mm).

CONCLUSIONS:

The accuracy of virtual ventriculostomy catheter placement achieved by participants using the simulator is comparable to the accuracy reported in a recent retrospective evaluation of free-hand ventriculostomy placements in which the mean distance from the catheter tip to the Monro foramen was 16 mm (+/- 9.6 mm).
