吻合血管的足内侧,第一跖背,足外侧三叶皮瓣的临床应用

目的：为修复多指皮肤缺损而设计了足内侧，第一趾背、足外侧的三叶皮瓣。方法：在解剖学研究的基础上，设计以胫前、足背血管为主干，跗内侧、第１跖背、跗外侧血管为分支，构成足内侧、第１跖背、足外侧的三叶皮瓣，游离移植修复多指皮肤同时缺损。结果：临床应用４例，３例三叶皮瓣全部成活，１例皮瓣有二叶坏死。结论：足内侧、第１跖背、足外侧三叶皮瓣游离移植的应用成功，为临床多指皮肤缺损的修复，提供了一种新的术式

The clinical application of free trifoliated flap combining medial pedal,first dorsal metatarsal and lateral pedal flaps

Objective:A free trifoliated flap was designed for repairing the skin defect of multiple fingers.Methods:Based on the anatomical studies,a trifoliated flap composed of medial pedal, first dorsal metatarsal and lateral pedal flaps was designed. The combined flap contained anterior tibial artery and dorsal pedal artey as the stem vessel for anastomosing with the supplying vessel. The three tributaries of dorsal pedal artery:medial tarsal artery, first dorsal metatarsal artey and lateral tarsal artery were contained in the three leaves respectively.The trifoliated flap harvested could be used to cover the skin defect of multiple fingers by free transplantation. Results:In the 4 clinically applied cases,3 combined trifoliated flaps survived completely. Two leaves of the rest one necrosed.Conclusion:The free trifoliated flap combining medial pedal,first dorsal metatarsal and lateral pedal flaps provided a new option for the repairing of multipe finger skin defect.
