The purpose of the present study was to establish the clinicoanatomical basis for the radial forearm flap. We conducted a morphometric investigation on 52 Japanese cadavers, of forearm vessels, for use in free forearm flaps. The mean inner diameter of the cephalic and median cubital veins at the interepicondylar line was 1.9 +/- 1.2 mm and 1.8 +/- 1.1 mm, respectively. Mean inner diameter of the radial artery and venae comitantes 1 cm distal to the origins of the radial and ulnar arteries was 2.3 +/- 0.5 mm and 1.6 +/- 0.5 mm, respectively. The longest segment of a superficial vein was 28.7 +/- 4.6 cm, it was measured between the basilic vein 5 cm proximal to the interepicondylar line and the cephalic vein at Lister's tubercle. The length of the radial artery was 18.1 +/- 1.7 cm. There were fewer valves in the basilic vein and cephalic vein proximal to the median cubital vein and in the brachial veins than in the distal antebrachial veins. From these results some of the clinicoanatomical considerations of forearm vessels which will form the clinicoanatomical basis of the free forearm flap should be clarified.
本研究的目的是建立桡侧前臂皮瓣的临床解剖学基础。我们对52具日本尸体的前臂血管进行了形态学研究，以用于游离前臂皮瓣。肱骨髁间线处头静脉和肘正中静脉的平均内径分别为1.9±1.2mm和1.8±1.1mm。桡动脉和伴行静脉在桡动脉和尺动脉起始处远侧1cm处的平均内径分别为2.3±0.5mm和1.6±0.5mm。一条浅静脉的最长段为28.7±4.6cm，是在肱骨髁间线近端5cm处的贵要静脉与Lister结节处的头静脉之间测量的。桡动脉的长度为18.1±1.7cm。与前臂远端静脉相比，肘正中静脉近端的贵要静脉和头静脉以及肱静脉中的瓣膜较少。根据这些结果，应阐明一些将构成游离前臂皮瓣临床解剖学基础的前臂血管的临床解剖学考量。
