在7例灌注红色乳胶的成人标本,30例七月以上胎儿、婴儿标本上,借助放大镜观察到手背桡动脉入掌前发出较恒定的第一掌背动脉,并沿第一骨间背侧肌表面行至食指桡侧在掌指关节附近,沿途发出分支分布于第二掌骨背侧皮肤。汇入头静脉的食指桡侧静脉通常成为此动脉的表面投影,对临床应用有指导意义。桡神经与血管相邻。上述关系提示可形成岛状血管、神经瓣。临床用以修复四例邻近缺损病例获满意疗效。
In seven adult samples infused with red latex and 30 fetuses and infants above July, a relatively constant first dorsal metacarpal artery was observed with a magnifying glass before the dorsal radial artery was inserted into the palm of the hand, and along the first interosseous dorsal muscle The surface line to the radial side of the index finger near the metacarpophalangeal joint, along the way issued branches distributed in the second metacarpal dorsal skin. Imported into the cephalic vein of the radial finger usually become the surface of this artery projection, the clinical application of guidance. Radial nerve adjacent to the blood vessels. The above relationship prompted the formation of island vessels, nerve valves. Clinically used to repair four cases of adjacent defects obtained satisfactory results.
