CTA在ROSA辅助脑深部电刺激术的应用

The application of computed tomographic angiography in the deep brain stimulation assisted by Robot of Stereotactic Assistant system

目的探讨CTA在立体定向手术机器人(Robot of Stereotactic Assistant,ROSA)辅助的脑深部电刺激术(DBS)的应用价值。方法 18例帕金森病和2例特发性震颤病人均行ROSA辅助DBS,利用ROSA观察穿刺针道在CTA图像上与血管重合情况。结果 20例病人术前计划植入电极39根,实际植入电极39根,其中植入丘脑底核37根,丘脑腹中间核2根。按传统定位与手术计划方法 ,17侧手术计划与CTA成像血管重叠,需重新调整手术路径。结论 CTA应用于ROSA辅助DBS,有助于提高安全性和精准性。

Objective To evaluate the application value of computed tomographic angiography （CTA） in the 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 ROSA system was used to observe the overlap of the puncture path and the vessel on the images of CTA. Results A total of 39 planned implant electrodes were successfully implanted in all 20 patients. Thirty-seven electrodes were implanted into the subthalamic nucleus and 2 into the ventral intermediate nucleus. A total of surgical planning of 17 side overlapped with vascular images of CTA, and the surgical path was readjusted. Conclusions CTA helps to improve the safety and accuracy when applied to DBS assisted by ROSA system.
