Guo外侧皮动脉蒂小腿后侧皮瓣的解剖及临床研究

目的 了解Ｇｕｏ外侧皮动蒂小腿后侧皮瓣行吻合血管的游离移植的可行性。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 Ｇｕｏ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

Anatomical and clinical studies on the free posterior leg flap pedicled with the lateral popliteal cutaneous artery]

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 performed 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 diameter 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 defects or for functional reconstruction.
