经过５７例５８块股前外侧皮瓣移植手术所见，皮血管大部属肌皮穿支型，且术前用多普勒血流仪作出的定位大多与实际相距较远。旋股外侧动脉降支下行途中发至皮瓣血管的穿支及浅出点的部位高低，深浅也有较大差异，这些均对术中皮血管的选取，解剖游离带来困难，甚至失误。作者提出：可根据不同情况采用①延长皮溶内侧缘切口；②切开皮瓣上端时逐层切开浅深筋膜；③逆行自下而上游离皮瓣；④对穿行于肌中的穿支游离时带上３～５ｍｍ肌袖；⑤对皮血管细小者同时取用２支或对皮血管进行组合吻合等方法加以处理。
After 57 cases of 58 anterolateral lateral flap grafting, most of the skin vascular dermis wear perforation, and preoperatively with the Doppler flowmeter to make the positioning are mostly far away from reality. Peripheral femoral artery descending artery sent to the flaps of blood vessels perforation and superficial point of the site of the level, the depth there is a big difference, these are the surgery of the vascular selection, anatomical separation difficult or even mistakes. The authors suggest that: ① according to different circumstances to extend the medial cut edge of the skin lysis; ② cut the upper end of the flap cut shallow shallow fascia; ③ retrograde bottom-up free flap; ④ wear through the muscle wear Branch free when the 3 ~ 5mm muscle sleeves; ⑤ fine skin blood vessels at the same time take 2 or on the combination of skin and blood vessels to be treated and other methods.
