The accuracy of deep brain stimulation assisted by Robot of Stereotactic Assistant system
Abstract：Objective To evaluate the accuracy and safety of deep brain stimulation (DBS) assisted by Robot of Stereotactic Assistant (ROSA) system. Methods A total of 18 Parkinson's disease patients and 2 essential tremor patients undergoing DBS assisted by ROSA system. The maximum and minimum distances of electrode deviation were recorded according to postoperative CT and the average distance was calculated. The intraoperative electrode related bleeding events and postoperative complications were also recorded. Results A total of 39 planned implant electrodes were successfully implanted in the 20 patients. Thirty-seven electrodes were implanted into the subthalamic nucleus and 2 into the ventral intermediate nucleus. The maximum deviation distance of x-axis was 2.13 mm, and the minimum was 0.09 mm, with an average of 0.68±0.43 mm. The maximum deviation distance of y-axis was 1.50 mm, and the minimum was 0.21 mm, with an average of 0.63±0.29 mm. Conclusion DBS electrodes implanted with the assistance of ROSA system is safe and accurate in implanting.
