Abstract: Objective To evaluate the efficacy and safety of subthalamic nucleus(STN) deep brain stimulation(DBS)under general anesthesia in the treatment of Parkinson’s disease(PD).The correlation between STN and to analyze subregion effective volume of tissue activated(VTA)and clinical symptoms.MethodsA total of 40 patients with PD who underwent bilateral STN DBS surgery in the Department of Neurosurgery,Nanchong from January 2O24 to June 2024 were collected. The clinical efficacy of patients in terms of movement(UPDRS-II),anxiety (HAMA),depression(HAMD),cognition(MoCA),quality of life(PDQ-39),etc were analyzed before surgery and three months after surgery. The Lead DBS software was used to reconstruct the electrodes,contacts and implanted target nuclei and subregions,and STN and subregion VTA could be accurately calculated,and the correlation between STN and subregion VTA and the preoperative and postoperative changes in clinical symptoms can be analyzed. ResultsAt the follow-up 3 months after surgery,UPDRS-II,HAMA and HAMD were significantly decreased( P=0.035 ), MoCA was not significantly decreased( P=0.078 ),and PDQ-39 was significantly decreased( Plt; 0.001). LEDD decreased significantly( Plt;0.001 ).Correlation analysis showed that the change of
UPDRS-II score was significantly positively correlated with total STN-VTA ( r=0.607 , Plt;0.001 ) and STN motor- VTA( r=0.587 , Plt;0.001 ). There was a significant positive correlation between life quality score and STN motor-VTA( r=0.612 , P=0.025 ). ConclusionsSTN DBS can significantly improve the motor symptoms,anxiety and depression of PD patients, improve the quality of life, reduce the amount of medication,and have litle impact on cognitive function. Lead DBS can be used as one of the auxiliary means of postoperative visual precision program control for STN DBS in PD.

帕金森病(Parkinson'sdisease,PD)是常見的神經系統退行性疾病,其癥狀包括運動癥狀和非運動癥狀。運動癥狀有運動遲緩、肌強直、靜止性震顫、姿勢平衡障礙,非運動癥狀則包括嗅覺障礙、睡眠障礙、尿頻、便秘、疼痛、焦慮抑郁情緒、認知功能減退等[1]。腦深部電刺激(deep brain stimulation,DBS)是治療中晚期PD的首選手術方法,其中丘腦底核(subthalamicnucleus,STN)電刺激術可以顯著改善患者癥狀,同時可以更多減少帕金森用藥量[2-3]本研究納入2024年1月—2024年6月于南充市中心神經外科行雙側STNDBS手術的40例PD患者,旨在全面分析STNDBS改善PD運動癥狀和非運動癥狀的效果,同時運用影像學3D重建技術和LeadDBS重建軟件分析STN及亞區有效刺激體積(volumeoftissueactivated,VTA)與PD癥狀變化的相關性,為PD患者DBS術后可視化程控提供理論依據,從而提高DBS手術后程控效率和治療效果。現報告如下。
