| 摘 要： | 应用闭合式颅骨开窗法观察大鼠大脑中动脉阻断（MCAO）后软脑膜微血管的改变。结果显示，MCAO后微动脉之间的吻合支发生严重的痉挛，而内外两端却均明显扩张，血液倒流，但速度较慢。微静脉明显扩张，血流速度变慢。末梢动脉收缩，血流速度变慢甚或停止。

| Abstract: | The change of the pial microvascular diameter and velocity after MCAO, was observed with close cranial window method. The results showed that after MCAO the anastomosis between the arterioles contracted severely, while the two ends of the arterioles dilated obviously, blood flowed backwards and slowly. The venules were dilated remarkably and the velocity decreased. The end artery contracted and the blood flow slowed down even stopped. |
