Pneumocephalus is a common complication of DBS surgery and could hamper correct intraoperative targeting. The aim of this work is to measure the displacement of deep cerebral structures due to pneumocephalus. Stereotactic co-ordinates of recognisable deep brain structures were evaluated in the pre-op and post-op CT scans of 14 patients who underwent bilateral DBS electrodes implantation. The amount of pneumocephalus was quantified. The differences between pre-op and post-op co-ordinates of deep structures were correlated to the pneumocephalus volume and thickness. It has been observed a displacement of deep brain structures up to 1.5 mm mainly in the posterior direction, which correlates with the amount of pneumocephalus.

Abstract
Pneumocephalus is a common complication of DBS surgery and could hamper correct intraoperative targeting. The aim of this work is to measure the displacement of deep cerebral structures due to pneumocephalus. Stereotactic co-ordinates of recognisable deep brain structures were evaluated in the pre-op and post-op CT scans of 14 patients who underwent bilateral DBS electrodes implantation. The amount of pneumocephalus was quantified. The differences between pre-op and post-op co-ordinates of deep structures were correlated to the pneumocephalus volume and thickness. It has been observed a displacement of deep brain structures up to 1.5 mm mainly in the posterior direction, which correlates with the amount of pneumocephalus.
