The Adipofascial Forearm Flap Based on the Perforators of the Distal Radial Artery

根基於遠端橈動脈穿通枝的前臂脂筋膜皮瓣

摘要


我們以根基於遠端橈動脈穿通枝的前臂脂筋膜皮瓣成功的重建二例前臂手部複雜性傷口。兩例均為受高壓電擊傷之中年男性,一例右前臂組織壞死,肌腱暴露;另一例左側手部皮膚肌肉壞死,肌腱及神經暴露。此皮瓣的血流供應來自於橈動脈的遠側穿通枝,一般位於橈骨莖突的近側端2.5公分到3.5公分。此皮瓣有寬廣的轉移範圍,可用皮瓣翻轉或移位的方式來覆蓋傷口,適用於重建前臂或手部的組織缺損。遠端橈動脈穿通枝前臂脂筋膜皮瓣的好處有:(1)皮瓣供應區可以直接縫合,不用植皮;(2)不必犧牲主要動脈(橈動脈);(3)手術方法簡單,節省時間;(4)脂肪組織可修剪,避免皮瓣過於肥厚。我們認此種皮瓣是重建前臂及手部一項有效的方法。

The adipofascial forearm flaps based on the perforators of the distal radial artery were successfully used to reconstruct complicated wounds over the hand and forearm in 2 patients. The attached point of the pedicle should be placed at least 2cm proximal to the radial styloid process, and the width of the distal pedicle may range from 2.5cm to 3.5cm. This flap not only has a wide arc of transposition, it also avoids the sacrifice of a main artery of the hand. The unsightly grafting scar at the donor site can be eliminated since the donor wound is closed primarily. The described technique is an easy and effective method for repair of the soft tissue defects of the hand and forearm.
