This postmortem study correlated intraoperative subthalamic nucleus (STN) deep brain stimulation (DBS) placement and postoperative magnetic resonance imaging (MRI) with autopsy findings in a patient who died suddenly 4 days postoperatively from a pulmonary embolism. The study demonstrates that (1) MRI stereotactic localization combined with microelectrode recording (MER) is an accurate way to target STN; (2) multiple MER tracts do not cause significant injury to the brain; and (3) postoperative MRI accurately demonstrates location of the DBS electrodes.
