目的探讨胚胎型大脑后动脉的存在对同侧大脑前动脉、颈内动脉和基底动脉内径可能的影响,为影像学分析提供参考信息。方法对50例来院接受3.0 T 3D-TOF-MRA检查者的检查结果进行回顾性分析。于最大密度投影法三维重建结果上测量后交通动脉、大脑后动脉P1段、大脑前动脉A1段、颈内动脉和基底动脉的内径,以统计学分析探索胚胎型大脑后动脉的出现是否对各目标血管的内径产生影响。结果本研究中20%的样本具备胚胎型大脑后动脉(10/50)。根据本研究结果,尚不能认为胚胎型大脑后动脉的存在伴随着大脑前动脉A1段正常率的变化。与不具备右侧胚胎型大脑后动脉的样本相比,具备右侧胚胎型大脑后动脉者的同侧颈内动脉内径较大( t=-2.108, P=0.040),而基底动脉内径较小( t=2.935, P=0.005)。左侧有胚胎型大脑后动脉组和无胚胎型大脑后动脉组间左侧颈内动脉内径的差异无统计学意义。左侧有胚胎型大脑后动脉组和无胚胎型大脑后动脉组间基底动脉内径的差异无统计学意义。结论胚胎型大脑后动脉并非少见。根据本研究结果,右侧胚胎型大脑后动脉的存在伴有右颈内动脉和基底动脉内径的改变。
目的探討胚胎型大腦後動脈的存在對同側大腦前動脈、頸內動脈和基底動脈內徑可能的影響,為影像學分析提供參攷信息。方法對50例來院接受3.0 T 3D-TOF-MRA檢查者的檢查結果進行迴顧性分析。于最大密度投影法三維重建結果上測量後交通動脈、大腦後動脈P1段、大腦前動脈A1段、頸內動脈和基底動脈的內徑,以統計學分析探索胚胎型大腦後動脈的齣現是否對各目標血管的內徑產生影響。結果本研究中20%的樣本具備胚胎型大腦後動脈(10/50)。根據本研究結果,尚不能認為胚胎型大腦後動脈的存在伴隨著大腦前動脈A1段正常率的變化。與不具備右側胚胎型大腦後動脈的樣本相比,具備右側胚胎型大腦後動脈者的同側頸內動脈內徑較大( t=-2.108, P=0.040),而基底動脈內徑較小( t=2.935, P=0.005)。左側有胚胎型大腦後動脈組和無胚胎型大腦後動脈組間左側頸內動脈內徑的差異無統計學意義。左側有胚胎型大腦後動脈組和無胚胎型大腦後動脈組間基底動脈內徑的差異無統計學意義。結論胚胎型大腦後動脈併非少見。根據本研究結果,右側胚胎型大腦後動脈的存在伴有右頸內動脈和基底動脈內徑的改變。

Objective To discuss the possible influence of the existence of fetal-type posterior cerebral artery(FTP) on the diameters of anterior cerebral artery (ACA) on the same side,internal carotid artery(ICA) on the same side and basilar artery ( BA ) in order to provide reference information for performing medical imaging analysis.Methods A retrospective analyse was performed on 50 cases examined by 3.0 T 3D-TOF-MRA in the hospital.Artery diameters of the posterior communicating artery , posterior cerebral artery P1 segment, ACA A1 segment,ICA and BA were measured on maximum intensity projection (MIP) images.Statistic methods were used to explore whether these diameters were influenced by the existance of FTP .Results 20%(10/50) of the cases had at least 1 fetal-type posterior cerebral artery .According to the results of this study ,it was not concluded that whether FTP comes with a different prevalence of A 1 hypogenesis .Right FTP comes with a larger right ICA diameter ( t=-2.108 ,P=0.040 ) and a smaller BA diameter ( t =2.935 , P =0.005 ) .There was no statistically significant difference between the left ICA diameters of the FTP group and the No FTP group .There was no statistically significant difference between the BA diameters of the FTP group and the No FTP group .Conclusions FTP is common.The existence of right FTP is accompanied by changes of right ICA diameter and BA diameter .
