摘要
目的:探讨在兔蛛网膜下腔出血(SAH)模型上,建立经颅多普勒超声(TCD)及脑血管造影(DSA)检测兔椎基底动脉脑血管痉挛(CVS)的新方法。方法:建立兔枕大池二次注血模型,同时行逆行颈内动脉插管椎基底动脉造影和TCD检测。结果:逆行性颈内动脉血管造影能清晰地显示椎基底动脉系统,注血前后血管管径有明显差异(P<0.05),平均血流速度注血后明显加快(P<0.05)。结论:一侧颈内动脉逆行插管椎基底动脉造影操作简单、可靠,采用TCD检测可获得兔椎基底动脉脑血管痉挛稳定的图谱。
Objective： To establish a new method for determing cerebral vaspaspasm（cvs） of basilar artery by cerebral angiography and transcranial Doppler ultrasound（TCD） in rabbits after experimental subarachnoid hemorrhage （SAH）. Method： Arterial blood was injected into the cistem magana two times. The angiography and TCD examination were performed at the same time. Results： The basilar arterial system could be clearly showed by retrograde angiography. The mean flow velocities of the basilar artery significantly increased after SAH. Conclusion： Retrograde angiography to the basilar arterial system is a reliable and easily managed method. The high quality and intensity of basilar arterial TCD image can be acquired by improving frequency of ultrasound signal.
