尾状核头三维空间形态与定位及其临床意义

Morphology and location of the head of caudate nucleus and its clinical significance

目的：对尾状核头进行三维空间形态和位置的解剖学研究，为脑的立体定向手术提供形态学基础。方法：５７只整脑１１４个尾状核头在三维切面上作２ｍｍ厚的连续切片，并在各脑片上直接进行观测。结果：尾状核头的前后径为１４．０±１．７ｍｍ、左右径为８．３±１．０ｍｍ，上下径为１７．７±３．７ｍｍ，体积为３１２７．６±５．２ｍｍ３，“靶心”坐标值：Ｘ轴为１１．９±１．１ｍｍ、Ｙ轴为２２．３±２．１ｍｍ、Ｚ轴为９．８±３．５ｍｍ，通过还原、重建，绘出空间投影轮廓图。结论：尾状核头的空间形态位置对脑的立体定向手术有参考价值。

Objective:The morphology and location of the head of caudate nucleus was studied to provide anatomic basis for stereotaxic technique of brainMethods:One hundred fourteen head of caudate nucleus(57 brain)were cut and observed with a thickness of 2 mm along sagittal section,coronary section and horizontal section separatelyResults:The head of caudate nucleus is 140±17 mm long,83±10 mm wide and 177±37 mm highIts average volume is 31276±52 mm3Conclusions:The results we provided here are very valuable on stereotaxic technique of brain operation
