脑立体定向术CT定位在治疗锥体外系疾病中应用

CT guided for treatment of extrapyramidal disorder in stereotactic neurosurgery

本文报告了我院采用 CT 与立体定向相结合,在 CT 图像上直接进行丘脑腹外侧核(VL)和苍白球(Pa)定位,治疗帕金森氏病、扭转痉挛、舞蹈病的初步结果。治疗结果证实了脑内某些神经核团 CT 定位的可行性。CT 定位较 X 线脑室造影定位缩短了手术程序,减少了手术创伤。而且 CT 的分辨率高图像清晰;与脑标准解剖图谱可比性强,易于推导出靶点的位置;同时图像直观,易于识别内囊等重要结构,避免了手术损伤,提高了手术安全性。本方法是一种简便实用的脑深部核团 CT 定位方法,能提高立体定向术治疗椎体外系疾病。

CT guided localization for VL and Pa in treatment of Parkson's disease, torsion-spasm and chorea by stereotactic neurosurgery has been reported.This method can simplify the localization process and improve surgery effect than ventriculography.CT have some advantages:1,high resolution,image clearer;2,the position of target can be easily reckoned;3,capsula interna,etc can be recognized increasing the safety of surgery.There- fore,it is simple,practical valuable approach for the localization of the deep brain nuclei group in EPD by stereotactic neurosurgery.
