Accuracy of Ventriculostomy Catheter Placement using a head- and hand-tracked high-resolution virtual reality simulator with haptic feedback
78 participants, made up of neurosurgery fellows and residents, were asked to perform a ventriculostomy catheter placement on the ImmersiveTouch training platform. Each participant was given one attempt, after which the distance between the tip of the catheter and the Monro Foramen was recorded.
The percent of participants who successfully reached the ventricle was 73%, and the mean Euclidean distance for all participants was 16.09 mm +/- 7.85 mm. These results were compared to a study done at the University of Missouri in Columbia where 98 cases of freehand ventriculostomy placements performed by neurosurgeons were analyzed for the same metrics. There, the percent of attempts that successfully reached the ventricle was 79%, and the mean Euclidean distance between the catheter tip and Monro Foramen was found to be 16 mm +/- 9.6 mm. With no statistical difference between the two sets of data, the findings suggest that the ImmersiveTouch simulator is able to realistically reproduce the ventriculostomy surgical experience.
“An important feature of realistic simulation is perfect overlap of the virtual catheter 3D image with the haptic stylus...Previous attempts at ventriculostomy simulation were not able to address this issue...The ImmersiveTouch platform appears to resolve these issues. The simulation is very realistic, as demonstrated by good correlation with previous experience among neurosurgical faculty members, residents, and medical students.”
