[Angiographical evaluation of extracranial carotid artery: comparison between Japanese and Hungarian].
We investigated the cervical level of carotid bifurcation, diameter of common carotid artery (CCA) and internal carotid artery (ICA) in 147 Japanese patients (150 arteries, range of age 31-79) and in 490 Hungarian patients (517 arteries, range of age 12-77). The cervical level of carotid bifurcation was determined by comparison with cervical vertebra. The carotid bifurcation of Japanese was most frequent at the lower part of 3rd cervical vertebra but in Hungarian the bifurcation was most frequent at the middle part of 4th cervical vertebra. Japanese carotid bifurcation was high-positioned compared with Hungarian. The mean CCA diameter in Japanese was 7.47 mm in male and 7.07 mm in female, in Hungarian 9.24 mm in male and 7.80 mm in female. The mean ICA diameter in Japanese was 4.96 mm in male and 4.83 mm in female, in Hungarian 8.56 mm in male and 7.66 mm in female. CCA and ICA diameter were larger in male than in female. The diameter of CCA had a significantly positive correlation with age (p < 0.002) but ICA had no similar correlation.
