指背逆行静脉干网状皮瓣修复手指中远端皮肤软组织缺损

The Netted Flap with a Retrograde Vein at the Finger's Reverse Side Repairs Skin Soft Tissue at Middle and Distal Parts of Finger's Defect

目的 :探讨指背浅静脉网的逆行皮瓣临床应用效果 ;方法 :15例应用指背浅静脉网形成 17个蒂在指背远端的逆行皮瓣修复同一手指及邻指的中远端皮肤软组织缺损 ;结果 :17个皮瓣术后 3～ 5d颜色红润 ,血运良好 ,其中 2个皮瓣远端出现花斑及水泡 ,4～ 7d皮瓣颜色转暗 ,出现程度不同表皮逐渐坏死 ,形成黑痂 ;结论 :指背逆行皮瓣 ,形成丰富的有轴型静脉的静脉网 ,且作为受区静脉内静脉压差及血流量大 ,血氧浓度高 ,皮肤菲薄 ,临床设计切取容易、方便、长宽比例可超过 3∶1,不受传统长宽比例限制 ,成活良好 。

Objective:To discuss the clinical application effects on the retrograde flap of superficial vein net of the finger's sreverse side.Methods:Fifteen patients used this technique to form 17 bases in order to repair the defect of soft tissue at the same finger and the neighbouring ones.Results:After the operations,17 ones are fine after 3-5 days,two of which appeared piebaldism and blister,then turned dim an d necrosised gradually in epiderm,and formed black scabs,which dropped after wto weeks.The whole flaps survived well.Conclusion:The retrograde flap at finger's reverse side forms rich venous network and an axial vein,as recipient site veins,the venous pressure and oxygen tension are high.On the other hand,the thin skin benefits clinical operation,and the proportion of length and width could beyond 3∶1.The above confirms that it is a good provide and recipient site.
