以骨间后血管及其返支为蒂串连皮瓣设计的解剖学基础

Applied anatomy of the serial flap pedicled with the posterior interosseous artery and its recurrent branch

目的 :为以骨间后血管及其返支为蒂串连皮瓣设计提供解剖学基础。方法 :在 40侧上肢标本上观测了骨间后动脉及其返支的来源、走行、分支、分布及吻合情况。结果 :前臂背侧下 2 / 3区的皮瓣由骨间后动脉供血 ,而上 1/ 3区由骨间后动脉返支 (或骨间返动脉 )供血。骨间后动脉起点外径 1.5mm ,管蒂长可达 15cm ,骨间后动脉返支起点外径 1.1mm ,血管蒂长 5cm。结论 :以骨间后动脉及其返支为蒂截取的串连皮瓣 ,向下可修复手部大面积组织缺损 ;

To provide anatomy basis for the serial flap pedicled with the posterior interosseous artery and its recurrent branch.Methods:The origin,course,branch,distribution and anastomosis of the posterior interosseous artery and its recurrent branch were dissected and observed on 40 sides of cadaver upper limbs.Results:The distal two third postcubital flap was supplied by the posterior interosseous artery.The artery was 1.5 mm in external diameter at its origin and could be separated freely up to 15 cm.The proximal one third postcubital flap was supplied by recurrent artery,whose extemal diameter was 1.1 mm and could be separated up to 5 cm.Conclusions:The posterior forearm serial flap pedicled with the posterior interosseous artery and its recurrent branch provide a new operation design for repairing the defect of soft tissue in hand,around elbow joint and the distal upper arm.
