We describe a curious congenital variation of human aortic arch (AA) branching pattern termed the "bovine aortic arch". Rather than arising directly from the AA as a separate branch as occurs in the most common AA branching pattern, the left common carotid artery moves to the right and merges from the brachiocephalic trunk. It is the normal AA branching pattern presented in a number of animals (canines, felines or Macaque monkeys) but it has nothing to do with anatomy of AA in ruminant animals, including cattle and buffalo. That is why it is one of the most widely misnomers used in medical literature whose origin is nowadays unknown.
我们描述了一种人类主动脉弓（AA）分支模式的奇特先天性变异，称为“牛主动脉弓”。在最常见的AA分支模式中，左颈总动脉是作为一个独立分支直接从AA发出，而在这种变异中，左颈总动脉向右移动并从头臂干汇入。它是许多动物（犬类、猫科动物或猕猴）呈现的正常AA分支模式，但与反刍动物（包括牛和水牛）的AA解剖结构无关。这就是为什么它是医学文献中使用最广泛的误称之一，其起源如今尚不清楚。
