Historical descriptions of the ulnar artery as the dominant vessel to the hand appear to be inconsistent with clinical experience. Anatomical dissections and radionucleotide flow studies of the ulnar and radial arteries at the wrist were performed. These failed to demonstrate any difference between the anatomical dimensions of these vessels, but the radial artery was shown to have a statistically greater blood flow compared to the ulnar artery. This finding suggests that, contrary to popular opinion, the radial artery is the dominant vessel to the hand.
将尺动脉描述为手部主要供血血管的历史记载似乎与临床经验不符。我们对腕部的尺动脉和桡动脉进行了解剖和放射性核素血流研究。这些研究未能显示出这些血管在解剖学尺寸上有任何差异，但与尺动脉相比，桡动脉的血流在统计学上显著更高。这一发现表明，与普遍观点相反，桡动脉才是手部的主要供血血管。
