有关手背静脉的研究较少。我们用成人上肢标本９０侧，在手术显微镜下对内径大于０．３ｍｍ的手背静脉进行了细致的解剖学观测。手背静脉的分布呈不均匀性．在手背近侧，８３．３％的标本静脉主支排列成桡、尺两组，在这两组静脉之间，对应于第Ⅱ掌骨近侧半、第Ⅱ掌骨间隙近侧半和第Ⅲ掌骨近侧半的区域，未见到内径大于０．３ｍｍ的静脉支，可称为“乏静脉区”。手背静脉由浅入深可以分为四层，即皮内静脉层、皮下静脉浅层、皮下静脉深层和深静脉层．以皮下静脉深层最为重要。这四层静脉相互重叠和相互交通，其骑跨支平均有３．２±０．６支，内径为０．９±０．３ｍｍ。手背静脉与手掌侧静脉通过掌骨间隙的交通支也非常丰富，平均有３．９±１．２支，平均内径为１．０±０．４ｍｍ。其中位于第Ⅰ掌骨间隙的交通支非常恒定（出现率１００％），平均管径为１．８±０．３ｍｍ，是手背静脉与掌深静脉之间最重要的交通支．在手背静脉与手掌静脉的交通支中，７０．０％有一个以上的静脉辩，其静脉瓣的方向均为由掌侧朝向背侧，使得血流由掌侧流向背侧，由深层流向浅层。
There are few studies on hand dorsal veins. We used a 90-degree adult upper extremity specimen to conduct a detailed anatomic observation of the dorsal hand vein with an internal diameter greater than 0.3 mm under a surgical microscope. The distribution of the dorsal veins is inhomogeneous. In the proximal part of the back of the hand, 83.3% of the main branches of the vein were arranged in radial and ulnar groups. Between the two groups of veins, the proximal half of the second metacarpal, the proximal half of the second metacarpal and the third metacarpal Near the half of the area, did not see the diameter greater than 0.3mm vein branch, can be referred to as “venous zone.” The dorsal hand vein can be divided into four layers from shallow to deep, that is, the intradermal venous layer, the superficial subcutaneous vein, the deep subcutaneous vein and the deep venous layer. The most important subcutaneous vein deep. The four layers of veins overlap each other and traffic, the average cross-branch riding 3.2 ± 0.6, an inner diameter of 0.9 ± 0.3mm. The dorsal veins and palm side veins through the metacarpal space traffic branch is also very rich, with an average of 3.9 ± 1.2, the average diameter of 1.0 ± 0.4mm. Among them, the traffic branch located in the first metacarpal gap was very constant (appearance rate was 100%) with an average diameter of 1.8 ± 0.3 mm. It was the most important traffic branch between the dorsal hand vein and the deep palmar vein. In the traffic branch of the dorsal and veins of the hand, 70.0% had more than one venous vein. The direction of the venous flap was from the palmar side to the dorsal side, which made the blood flow from the palmar side to the dorsal side and from the deep side to the dorsal side Floor.
