Studies evaluating the static and dynamic characteristics of the common carotid bifurcation are described. Slow motion angiographic frames, real time B-mode images and time position M-mode tracings have demonstrated appreciable vessel wall motion with an increase in distensibility at the carotid bulb compared to the proximal common carotid artery. Histopathological studies suggest that changes in the carotid artery elastin and collagen structure may contribute to the increased distensibility at the carotid bulb. The presence or absence of a cervical bruit did not correlate with the ultrasonic demonstration of plaque or blood flow turbulence. Mechanical factors relating to the development of symptoms of cerebral ischaemia are discussed.
描述了评估颈总动脉分叉处静态和动态特征的研究。慢动作血管造影图像、实时B模式图像和时间位置M模式描记显示，与近端颈总动脉相比，颈动脉球处血管壁运动明显，扩张性增加。组织病理学研究表明，颈动脉弹性蛋白和胶原蛋白结构的变化可能导致颈动脉球处扩张性增加。颈部杂音的有无与斑块或血流紊乱的超声显示无关。讨论了与脑缺血症状发展相关的机械因素。
