While performing carotid angiography in a 76-year-old man, we found that the right internal carotid artery repeatedly opened and closed during the examination. The patient experienced no related neurologic events. The explanation, confirmed at surgery, was that a flap associated with an atherosclerotic plaque had acted as a ball valve.
在对一名76岁男性进行颈动脉血管造影时,我们发现右侧颈内动脉在检查过程中反复开闭。患者未出现相关神经事件。手术证实,原因是与动脉粥样硬化斑块相关的一个瓣片起到了球阀的作用。
