Charlottesville, VA (October 16, 2018).

Researchers from Beijing have developed a new technique of external ventricular drain (EVD) insertion that involves the use of a mixed-reality holographic computer headset.

The new technique is described and illustrated in the article, "A wearable mixed-reality holographic computer for guiding external ventricular drain insertion at the bedside," by Ye Li, M.D., Ph.D., and colleagues, published today in the Journal of Neurosurgery.

Repeated passes of the catheter pose an increased risk of complications (hemorrhage or infection) to the brain.

The researchers tested the readily available Microsoft HoloLens mixed-reality holographic computer headset while treating 15 patients.

Two-dimensional CT-generated data were converted into three-dimensional data, on the basis of which a surgical plan could be created.
