[Analysis of the high-resolution real-time sonographic images of the carotid bifurcations in normal adults].
The high-resolution real-time sonographic images in 186 carotid bifurcations (CB) of 93 selected normal persons were quantitatively analysed for 9 parameters including the diameters of the internal carotid arteries (CCA), the bifurcating angles of the ICA and ECA, and the angles between the ICA and ECA. The results of all the measurements were analysed with the relevant statistical methods. The normal field (99% limit) of CB in every age group was shown in this paper. The normal range of the measured values of the carotid bifurcations in each age group was calculated, and the laws governing their changing trends and their clinical significance were discussed.
