Cartesia

After the mounting of the SF, the patient was transferred to the radiology department where a cerebral CT scan was performed and fused with the pre-operative planning images. Thereafter, the patient was transferred to the operating room (OR).
The patient was positioned supine, with an oxygen mask in place. Antibiotic prophylaxis was achieved using intravenous cefazolin (Céfazoline Sandoz, Sandoz Pharmaceuticals AG, Rotkreutz, Switzerland). Mild sedation was achieved during patient preparation using intravenous propofol (Propofol-Lipuro 1% 1 g/100 ml, B Braun Medical, Sempach, Switzerland). Local scalp anesthesia was performed using 10 cc rapidocaïn (rapidocaïn 200 mg/20 ml, in-house preparation) for each incision. Two arciform incisions were then performed under analgo-sedation and careful hemostasis was achieved. Two burr holes were drilled. Thereafter, the sedation was stopped to obtain full collaboration of the patient during micro-electrode recording and neurological testing. Once the definitive position of the electrode was decided, a definitive electrode was positioned under X-ray control (Boston Scientific Cartesia, Boston Scientific, MA, USA). Once both definitive electrodes were in place, the skin was closed using subcutaneous sutures and staples.
