How I do it - asleep DBS placement for Parkinson's disease

Abstract

Background: Traditionally, functional neurosurgery relied in stereotactic atlases and intraoperative micro-registration in awake patients for electrode placement in Parkinson's disease. Cumulative experience on target description, refinement of MRI, and advances in intraoperative imaging has enabled accurate preoperative planning and its implementation with the patient under general anaesthesia.

Methods: Stepwise description, emphasising preoperative planning, and intraoperative imaging verification, for transition to asleep-DBS surgery.

Conclusion: Direct targeting relies on MRI anatomic landmarks and accounts for interpersonal variability. Indeed, the asleep procedure precludes patient distress. A particular complication to avoid is pneumocephalus; it can lead to brain-shift and potential deviation of electrode trajectory.
