摘要目的 分析运动障碍性疾病立体定向手术中脑出血危险因素,以降低脑出血并发症.方法 对689例运动障碍性疾病进行了立体定向脑深部刺激术(DBS)和毁损术,共有853个靶点进行了手术治疗,其中丘脑底核(STN)刺激术188个,丘脑腹中间核(Vim)刺激术5个,苍白球内侧部DBS 2个,苍白球腹后部毁损术(PVP)478个,Vim毁损术180个.结果 术后无症状性脑出血14例,症状性脑出血10例.有高血压病史患者脑出血发牛率明显高于无高血压病史患者.在微电极记录2-4条针道的手术靶点中,脑出血发生率显著高于微电极记录1条针道的脑出血发生率.DBS、PVP及Vim毁损术靶点脑出血发生率分别为0.5%、3.6%及3.3%,前者发生率明显低于后两者.结论 高血压病史是帕金森病立体定向手术并发脑出血的危险因素,微电极记录针道数与脑出血发生率成明显正相关,脑深部刺激术是较毁损术更安全的外科治疗方法.

abstractsObjective To analyze the risk factors of intracranial hemorrhage in deep brain stimulation(DBS)and ablation procedures in a large series of patients with movement disorders in order to reduce the incidence of hemorrhage.Methads 689 patients treated with DBS and ablation procedures were enrolled in this study(DBS in 113 cases,ablation in 576 cases and DBS after prior unilateral ablation procedure in 11 cases).In 853 target procedures,DBS was employed in 195 targets(188 subthalamic nucleus targets,5 ventral intermediate targets and 2 internal globus pallidus targets),the ablation procedure was employed in 658 targets(478 intemal globus pallidus targets,180 ventral intermediate targets).Results There were 14 asymptomatic and 10 symptomatic intracranial hematomas.There wag a statistically significant relationship between the risk of symptomatic hematoma and hypertension.The incidence of hematoins in 2～4 microelectrode recording penetrations was6.9%.whereas 2.2%in 1 microelectrode recording penetration.There Wag only one agymptomatic hematoma in 195 DBS targets.Conclusion The humber of micreelectrode passes used to determine target location is correlated with the risk of hemorrhage.Ablation procedure carries a higher risk of hemorrhage than that of DBS.
