摘要
为探讨环椎沟桥(下称沟桥)是否影响椎动脉(VA)供区.本文应用经颅多谱勒对临床上疑为椎—基底动脉供血不足的35例单侧环椎沟桥患者进行了椎动脉(VA)颅内段检测,发现沟桥侧VA痉挛的发生率要高于对侧(P<0.05).表明环椎沟桥与VA痉挛有一定关系,说明沟桥是导致VA供血不足的因素之一.
For studying whether the blood supply of vertebral artery(VA) is affected by the bone structure over the groove for VA of atlas, the author used transcranial doppler system(TCD) to measure vertebral arteries(the section in the cranium)of 35 cases being suspected clinically having vertevrolis-basilas insufficiency and while having the bone structrue over the groove for VA of atlas on one side.The results showed that the incidence of spasm of the vertevral arteries on the side having this kind of bone structurd was higher than on the other side(P < 0.05) .It demonstrated that there was a connection between two aspects and the bone structurd over the groove of VA for atlas was one of the factors for the vertebrolis-insufficency.
