摘要
目的了解腘外侧皮动脉蒂小腿后侧皮瓣行吻合血管的游离移植可行性。方法对22例成人下肢新鲜标本进行了解剖学观察测量。结果 腘外侧皮动脉出现率100％,其起始处外径1.28±0.25mm,血管走行恒定,并恒与腓肠外侧皮神经伴行,血管全长20.0±5.7cm,远端与腓动脉穿支有联系。以此为蒂制成的小腿后侧皮瓣有伴行静脉及小隐静脉可供吻合,回流良好。临床应用此皮瓣行带神经的吻合血管的游离移植7例,均获成功。结论本游离皮瓣具有一定的优点,适用于中小面积或功能部位组织缺损的修复。
Objective To investigate the feasibility of free transference of the posterior leg flap which is supplied by the lateral popliteal cutaneous artery. Methods Anatomical dissection is per- formed in twenty-two freshly amputated adult lower extremities. Results The discovery rate of the lateral popliteal cutaneous artery is 100%. The vessel is 20.0±5.7 cm in length with an exterior diame- ter of 1.28±0. 25 mm at the junction of the popliteal artery. The course of the artery is constant, and it is usually accompanied by the lateral sural cutaneous nerve. Seven operations using this free flap have been performed successfully. Conclusion The flap is suitable for repairing medium-sized soft tissue de- fects or for functional reconstruction.
