游离皮瓣移植术中血液循环判断

The identification of blood circulation in the operation of free flap transplantation

目的探讨游离皮瓣移植术中血液循环判断对皮瓣手术成功的指导意义。方法对2007年3月~2009年12月26例外伤后皮肤和软组织缺损的患者行游离背阔肌和股前外侧皮瓣移植,观察术中吻合血管后皮瓣的弹性、色泽,吻合处静脉血流的颜色和术后皮瓣的存活之间的关系。结果游离皮瓣移植术中吻合血管后,如皮瓣的弹性正常、色泽逐渐转为原供区切取前色泽,静脉血流颜色转为（淡）紫红色,则皮瓣术后存活良好。结论游离皮瓣移植术中静脉血流和皮瓣颜色等血液循环的判断对皮瓣存活有重要的参考的意义。

Objective To explore the significance of identifying blood circulation in the operation of free flap transplantation to a successful flap surgery.Methods Twenty-six patients who suffered from trauma and soft tissue loss in our hospital from Mar.2007 to Dec.2009 received free skin flap transplantation with latissimus dorsi muscle and thigh anterolatera flap.The correlation between flap flexibility,color,the color of the venous blood,and flap survival after surgery were observed.Results After surgery,it was found that the flap survival was good if the flap flexibility and the color of the flap had the same color with the donor area and the venous blood became mauve.Conclusion The identification of blood circulation in the operation of free flap transplantation is important to a successful flap surgery.
