Abstract: 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 cistern 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.
