本文采用先进的彩色三维经颅多普勒超声扫描仪(3D-TCD),观察脑动脉硬化病人在血流变正常或高粘血症下,大脑中动脉(MCA)血流速度的改变,探讨血流变变化对脑血流的影响。结果提示:当高粘血症时,MCA 的血流速度较正常血流变组明显减慢,二者之间有显著性差异(P<0.001)。
In this paper, advanced color three-dimensional transcranial Doppler ultrasound scanner (3D-TCD) was used to observe the changes of blood flow velocity in middle cerebral artery (MCA) under the condition of normal blood flow or hyperviscosity in patients with cerebral arteriosclerosis Effect of changes in blood flow on cerebral blood flow. The results suggest that when hyperviscosity is high, the blood flow velocity of MCA is significantly slower than that of the normal blood rheology group (P <0.001).
