在探寻上臂游离皮瓣供区的研究中,对上臂外侧面血供系统的研究至今尚未如内侧面那样受到应有的重视。一些研究表明,上臂内侧的血管系统变异较大。作者通过尸体解剖研究发现,上臂外侧的血管系统恒定。肱深动脉的终末支——后桡侧副动脉营养三角肌止点至肘之间的上臂后外侧皮肤,范围较大,血供可靠。 In the study of the upper arm free flap donor area, the study of the lateral blood supply system in the upper arm has not received the same attention as the medial aspect. Some studies have shown that there is a large variation in the vascular system inside the upper arm. Autopsy studies by the authors found that the vasculature outside the upper arm was constant. The terminal branch of the deep brachial artery - the radial artery of the parasternal artery deltoid muscle to the elbow between the posterior lateral arm of the skin, a large, reliable blood supply.
