Quantitative percutaneous flow velocity measurements are possible in carotid arteries by means of a directional Doppler flow velocity device and registration on a polygraph. Carotid flow velocity changes were recorded during catheterization of the ascending aorta and common carotid artery and after infusion of 20 cc contrast medium in the ascending aorta. The results indicate an increase in the flow velocity in the right common carotid artery after infusion of the contrast medium in the ascending aorta, which is thought to be attributed to a diffuse vasodilatation, at least in the cerebral circulation. The catheterization of the ascending aorta and common carotid artery seems to interfere with the common carotid flow velocity.
通过定向多普勒流速仪和多导记录仪记录，可对颈动脉进行经皮定量流速测量。在升主动脉和颈总动脉插管期间以及在升主动脉注入20毫升造影剂后，记录颈动脉流速变化。结果表明，在升主动脉注入造影剂后，右侧颈总动脉的流速增加，这被认为至少在脑循环中归因于弥漫性血管扩张。升主动脉和颈总动脉的插管似乎会干扰颈总动脉的流速。
