ID: 214384 Postoperative DBS Pneumocephalus Volume in Patients With Parkinson's Disease: Correlating Burr-Hole Size and Intraoperative Duration

Pneumocephalus can be linked to brain shift and impact the accuracy of stereotactic Deep Brain Stimulation (DBS) surgery. Previous literature has been unable to establish a correlation between burr hole size and the amount of pneumocephalus seen. Consequently, this work sought to determine if intraoperative burr hole size positively correlated with the volume of pneumocephalus observed on postoperative CT imaging in patients who underwent DBS. The duration of the surgery was also considered in order to see its impact on the pneumocephalus volume.
