The vascular anatomy of the hand has already been widely described macroscopically. However, there are very few papers that study the pattern of normality of in vivo vascularisation that describe and analyse the main arteries of the hand. The aim of this paper was to carry out a study to serve as a reference for the normal values of size and flow of the radial and ulnar artery at the level of the wrist, and the digital radial and ulnar arteries at the level of the fingers.
A descriptive observational cross-sectional study on 200 hands in 100 healthy volunteers aged between 20-30years. Doppler-colour ultrasound was performed on the ulnar and radial arteries in the wrist, as well as on the radial and ulnar digital arteries in each finger. Once the measurements had been taken, a general comparative analysis was performed also taking laterality, dominance and gender into account.
It was observed that the radial artery is larger in size than the ulnar at wrist level, however, it was the ulnar artery that showed flow dominance at this level. At finger level, the arteries are greater in size and flow in the areas of the fingers more protected from injury (digital ulnar artery in the first three and radial artery in the fourth and fifth digits).
手部的血管解剖结构已经被广泛地从宏观层面进行了描述。然而，很少有研究描述和分析手部主要动脉的正常血管化模式的论文。本文的目的是进行一项研究，为腕部桡动脉和尺动脉以及手指桡动脉和尺动脉的大小和流量的正常数值提供参考。
这是一项对 100 名年龄在 20-30 岁之间的健康志愿者的 200 只手进行的描述性、观察性、横断面研究。对腕部的尺动脉和桡动脉，以及每个手指的桡动脉和尺动脉进行多普勒彩色超声检查。在测量后，还考虑了侧别、优势和性别等因素，进行了一般的比较分析。
观察到在腕部桡动脉的尺寸大于尺动脉，但在该水平尺动脉显示出流量优势。在手指水平，手指更不易受伤的区域（第一至第三指的尺动脉和第四、五指的桡动脉）的动脉尺寸和流量更大。
