The most common aortic arch branching variation described in literature is the common origin of the brachiocephalic trunk and left common carotid artery ("bovine arch" / type II aortic arch), with an incidence of 7.2-21.1%. The first aim of this study was to investigate the prevalence of bovine arch in the fetuses. The second aim was the hemodynamic evaluation of the epiaortic vessels.
In two years we examined 742 pregnant women and it was possible to obtain a good hemodynamic evaluation in 39 patients. Among the 39 fetuses, we found 6 with bovine arch. The blood flow of all epiaortic vessels and of MCA was evaluated.
Among the 742 fetuses examined, the bovine aortic arch was identified in 45 patients (6.06%). The hemodynamic evaluation of the epiaortic vessels showed statistically significant differences between the bovine arch and normal aortic arch.
The presence of bovine aortic arch in the fetus is characterized by some hemodynamical differences. They could have a possible relationship with the incidence of some pathologies in adult life. Prenatal knowledge of anatomic variants of the aortic arch can bring benefits to the individual's health for future possible cardiovascular investigations.
文献中描述的最常见的主动脉弓分支变异是头臂干和左颈总动脉共同起源（“牛型主动脉弓”/II型主动脉弓），发生率为7.2 - 21.1%。本研究的首要目的是调查胎儿中牛型主动脉弓的患病率。第二个目的是对主动脉弓上血管进行血流动力学评估。
在两年时间里，我们检查了742名孕妇，其中39例患者获得了良好的血流动力学评估。在这39例胎儿中，我们发现6例有牛型主动脉弓。评估了所有主动脉弓上血管和大脑中动脉的血流。
在检查的742例胎儿中，45例（6.06%）发现有牛型主动脉弓。主动脉弓上血管弓上血管的血流动力学评估显示，牛型主动脉弓与正常主动脉弓之间存在统计学上的显著差异。
胎儿中牛型主动脉弓的存在具有一些血流动力学差异。它们可能与成年后某些疾病的发生率存在关联。产前了解主动脉弓的解剖变异可为未来可能的心血管检查对个人健康带来益处。
