在１２侧灌注颜料的新鲜下肢上，解剖观察了以旋股外侧动脉降支为蒂的股前外侧真皮下血管网皮瓣血供、真皮下血管网的构筑及静脉回流，结果显示：①皮动脉穿出深筋膜后随即分成２～６支主要分支各自斜行浅筋膜途中发出浅筋膜分支、真皮下血管网分支和混合型三种分支；②真皮下血管网分支在真皮下层形成“血管树”或“蜘蛛痣”状吻合稠密的血管网；③在制备股前外侧真皮下血管网皮瓣时需保留血管蒂周围２．５ｃｍ不超薄，其余周边部分超薄至保留皮下脂肪２～３ｍｍ；④真皮下静脉也吻合成网，通过皮动脉伴行静脉或股外侧浅静脉回流。文中讨论了皮瓣的血供特点和优点。
On the fresh lower extremities perfusing pigment on 12 sides, we observed the blood supply of subdermal subdermal vascular flap pedicled with the descending branch of lateral femoral circumflex artery, the construction of subdermal vascular network and the venous return. The results showed: Immediately after penetrating the deep fascia, the artery is divided into 2 to 6 main branches, each of which branches into superficial fascia, subdermal vascular network and mixed type. 2) Subdermal vascular network branches in the dermis “Vascular tree” or “spider nevus” anastomosis thick vascular network; ③ in the preparation of pre-anterolateral subdermal vascular network flap to keep 2.5cm around the vascular pedicle is not ultra-thin, the rest of the peripheral part of the thin to retain subcutaneous fat 2 ~ 3mm; ④ subcutaneous vein is also consistent with the formation of mesh, through the lateral artery or vein with superficial femoral vein reflux. The article discusses the characteristics and advantages of flap blood supply.
