前臂内侧皮神经的血供特点及其在皮瓣设计中的意义

目的 为临床设计前臂内侧皮神经营养血管皮瓣提供形态学依据。方法 用量微解剖和标本透明法研究３７侧上肢人侧上神经解剖及其与贵要静脉的关系以及营养血管的来源、位置、口径、对皮神经的营养形式等。结果 前臂内侧皮神经全程由神经旁血管营养。神经旁血管由来源于肱动脉与尺动脉的皮肤动脉分支吻合形成。前臂内侧皮神经与贵要静脉在１ｃｍ左右范围内伴行。结论 顺沿贵要静脉，可切取前臂内侧皮神经、神经旁血管或神经皮肤穿支

The characteristics of blood supply of the medial antebrachial neurocutaneous nerve and it's significance in designing flap

Objective To supply morphologic basis for designing the medial antebrachial neurocutaneou vascular flap. Methods Microanatomy and transparent specimens made by colored latex injection were applied to study the surgical anatomy of the medial antebrachial neurocutaneous nerve (MAN) and it's relationship to basilic vein, the origin, orientation,caliber of neurovascular cutaneous perforators and it's nutrient pattern to the MAN. Results The MAN got its blood supply by paraneural vessels which constituted of 4 cutaneous perforators' The paraneural vessels supply not only the MAN,but also it's adjacent flap. The MAN was accompanied by basilic vein about 1 cm away from it. Conclusion Along basilic vein,medial antebrachial neurocutaneous vascular flap could be designed and used to repair soft tissue defects around the elbow and wrist
