Accuracy and safety of targeting using intraoperative “O-arm” during placement of deep brain stimulation electrodes without electrophysiological recordings

Highlights • Deep brain stimulation (DBS) lead can be implanted safely and with accuracy using intraoperative “O-arm”. • Intraoperative “O-arm” provides three dimensional accuracy and can be used in selected patients. • Frequent use of this imaging modality is required to master the nuances associated with this technology in the operating room. • Randomized controlled studies are required to validate the efficacy of intraoperative “O arm” during DBS surgery.
