骨间前动脉背测支岛状皮瓣的临床应用

THE CLINICAL APPLICATION OF POSTERIORFOREARM lSLAND FLAP PEDICLED ON DORSALBRANCH OF ANTERIOR INTEROSSEOUS ARTERY

观测红色乳胶染料灌注的上肢２８侧，发现骨间前动脉在旋前方肌上缘发出背侧支，其穿过骨间膜即发出一皮支，该皮支沿拇短伸肌与指总伸肌之肌隙穿出，该皮支血管解剖恒定，长２．２６±０．２４ｃｍ，可作为血管蒂的一部分连同背侧支主干一起向远端逆转，形成岛状皮瓣，用于修复拇指、虎口、手背皮肤软组织缺损，临床应用８例，效果良好。

AbstractAccording to 28 cadaveric upper limbs observa-tion, it turned out to be that the anterior interosseousartery issues one dorsal branch from the proximal mar-gin of pronator muscle after perforating the in-terosseous membrane, and the dorsal branch issues onecutaneous branch which passs through the muscu-lophrenic between the extensor pollicis longus muscleand extensor pollicis brevis muscle and enters skin ter-ritory of posterior forearm. The cutaneous branch isinvariable and 2. 2+0. 24cm in length. The vascularpedicle can be made up by the cutaneous branch andthe dorsal branch of anterior interosseous artery. Thesoft tissue defects of the thumb, the first web spaceand the dorsal hand. The satisfactory result have beenachieved through 8 cases clinical application.
