摘要

我们通过对33具尸体的主动脉弓及其分支进行尸检测量,研究了葡萄牙人主动脉弓的解剖特征。我们发现有相当少数的个体(占总数的18%)没有常见的3支主动脉弓;有趣的是,所有2支弓见于女性,所有4支弓见于男性。动脉分支可以来自弓的上升段(占总支的61%)或水平段(占总支的39%)。我们的测量表明,分支的弹簧与主动脉弓的变窄有关,因此第一分支和最后分支起源的主动脉弓直径差异可达11毫米。我们发现主动脉弓的动脉分支的相对口径取决于它在弓的起源位置:在主动脉弓的分支起源于弓的水平段,第一个动脉分支总是三个最宽的,而在主动脉弓的分支从弓的上升段出来,最宽的动脉分支是第三个。我们的数据支持这样一种观点,即人类主动脉弓的解剖排列存在广泛的变异,并提供了葡萄牙人群中主动脉弓变异的患病率信息。

Variations in the anatomical organization of the human aortic arch. A study in a Portuguese population.

We have studied the anatomical features of human aortic arches in a sample of the Portuguese population using postmortem measurements of the arches and their branches in 33 cadavers. We found that there is a significant minority of individuals (18% of the total) who did not present the usual 3-branched aortic arch; interestingly, all 2-branched arches were seen in women and all 4-branched arches were observed in men. The arterial branches could spring either from the ascending segment of the arch (61% of total) or from its horizontal segment (39% of total). Our measurements showed that the springing of the branches was associated with the narrowing of the aortic arch, so that the difference in the diameter of the aortic arch between the origin of the first and last branches could reach up to 11 millimeters. We found that the relative caliber of the arterial branches of the aortic arch depended on the position of its origin at the arch: in aortic arches with branches that were originated at the horizontal segment of the arch the first arterial branch was always the widest of the three, whereas in aortic arches with branches coming out at the ascending segment of the arch the widest arterial branch was the third one. Our data support the view that there is a wide spectrum of variations in the anatomical arrangement of the aortic arch in humans, and offer information on the prevalence of aortic arch variations in a Portuguese population.
