In the origin of the arteria radialis a loop-like formation was found. This unusual arrangement can be explained in the following way: from both the a. brachialis continuing into the a. ulnaris and the a. brachialis superficialis continuing into the a. radialis, aa. recurrens radialis branch off, which are connected by an anastomosis. The reduction of the a. brachialis superficialis results in the fact that the aa. recurrens radialis with their anastomosis have to take over the blood supply of the a. radialis and thus lead to the loop-like formation.
在桡动脉起始处发现了一个环状结构。这种不寻常的排列可以通过以下方式解释：从延续为尺动脉的肱动脉以及延续为桡动脉的肱浅动脉中，发出桡返动脉，它们通过一个吻合支相连。肱浅动脉的变细导致桡返动脉及其吻合支不得不承担起桡动脉的血液供应，从而形成了环状结构。
