肘下动脉穿支蒂前臂外侧皮神经营养血管皮瓣的解剖基础

目的 为肘下动脉穿支蒂前臂外侧皮神经营养血管皮瓣修复肘部软组织缺损提供解剖学基础.方法在30侧动脉内灌注红色乳胶的成人上肢标本上解剖观查:①前臂外侧皮神经的走行与分布;②肘下动脉与前臂外侧皮神经营养血管间吻合关系.另在1侧新鲜标本上进行摹拟手术设计.结果①前臂外侧皮神经主干行于前臂桡侧,分布于前臂外侧1/3区域;②营养血管为多节段、多源性,其中肘下动脉的位置相对恒定,在头静脉与深静脉系统的交通支形成的倒"V"状顶点到达皮肤,并分出众多的细小血管与前臂外侧皮神经的神经旁和神经干血管链的分支密切吻合.结论 可形成肘下动脉穿支蒂前臂外侧皮神经营养血管皮瓣顺行转位修复肘部软组织缺损.

Abstract：

Objective To provide anatomical basis for lateral antebrachial neurocutaneous flap pedi-cled with inferior cubital artery perforator in repairing tissue defects around elbow joint. Methods Thirty embalmed upper limbs of adult cadavers perfused with red latex were used for this study, and followings were observed:①The course and distribution of lateral antebrachial cutaneous nerve; ②Anastomoses between inferior cubital artery and nutrient vessels of lateral antebrachial cutaneous nerve. Mimic operation was performed on other side of fresh specimen. Results ①The main trunk of lateral antebrachial cutaneous nerve (LACN) lined in the radial forearm and distributed in the 1/3 region of lateral forearm. ①The nutritional vessels of the flap were plurisegmental and polyphyletic. The inferior cubital artery which was relatively constant reached to skin through "V"-shaped peak formed by communicating branches of cephalic vein and deep venous system. They also gave off large number of small veins, which closely aligned with perineural branches and neural stem vascular chain of lateral antebrachial cutaneous nerve. Conclusion The lateral antebrachial neurocutaneos flap pedicled with inferior cubital artery perforator can be formed to repaire tissue defects around elbow joint.
