手指逆行岛状皮瓣的应用研究

Application of pedicle tetroversal island flap in finger.

我们设计了手指近节侧方逆行岛状皮瓣修复手指指端皮肤斜行缺损，临床应用７例９指，均获成功。皮瓣最大面积２．０ｃｍ×３．０ｃｍ，最小面积１．０ｃｍ×１．５ｃｍ。通过对４具尸体８只手的应用解剖研究，结合文献及临床观察发现此皮瓣的静脉回流为指动脉→皮瓣→指静脉→逆行至指静脉远端→末节指背静脉→中节指背静脉→近节指背静脉→手背静脉，故术后发生静脉危象较少。手指近节侧方逆行岛状皮瓣操作简单、成功率高，修复后手指可早期功能锻炼．特别适宜修复示、中、环、小指指端斜行皮肤的缺损。

Abstract A pedicle retroversal island flap was designed to treat slant finger tip defects in seven patients. Excellent result was obtained after at least one month's follow up with regard to the sensation recovery and good appearance.Anatomical research was done to investigate the venous drainage of the flap.Indications and advantages of the operation were discussed.
