Surgical procedure
A magnetic resonance image (MRI) scan was performed using a computerized
navigational system to identify the target structure, and a trajectory
was chosen. Two DBS electrodes were bilaterally implanted in the area of
the MFB (Medtronic model 3389) in the posteromedial hypothalamic area
just anterior of the red nucleus, and two electrodes in the area of the
BNST (Medtronic model 3387). After the procedure, the electrode
positions were verified with a postoperative computed tomography scan
fused with the preoperative stereotactic MRI (Figure 1).
