摘要
目的 为临床设计皮神经营养血管皮瓣和对该类皮瓣与某些局部移转的静脉皮瓣的关系的认识提供解剖学基础。方法 用显微解剖法、标本双色透明法观测前臂内侧皮神经血供、贵要静脉与前臂内侧皮神经及其营养血管的关系和前臂外侧皮神经的血供、头静脉与前臂外侧皮神经及其营养血管的关系。结果 前臂内、外侧皮神经的血供形式不相同 ,前者由神经旁血管供养 ,后者由主要动脉和神经旁血管共同供养。头静脉与前臂外侧皮神经及其营养血管 ,贵要静脉与前臂内侧皮神经及其营养血管三者相伴行 ,皮神经与浅静脉干距离一般不超过 1cm ,神经旁血管与浅静脉干距离约 0 3～ 1 2cm。结论 顺沿浅静脉干可切取皮神经营养血管皮瓣 ;前臂内侧皮神经营养血管皮瓣与前臂外侧皮神经营养血管皮瓣蒂部形式应有所不同 ;某些局部移转的静脉皮瓣可能是皮神经营养血管皮瓣。
Objective To provide an anatomic basis for designing the flap pedicled with neurocutaneous nutrient vessels,and for further understanding of this flap and its relations with other local venous flaps. Methods Microanatomy and red and blue latex injection transparency method were applied to study ①The medial antebrachial cutaneous nerve (MACN), the lateral antebrachial cutaneous nerve (LACN) and their nutrient vessels; ②The relationship between the basilic vein and MACN and its nutrient vessels; and ③The relationship between the cephalic vein and LACN and its nutrient vessels. Results MACN is vascularized by paraneural vessels and LACN is by both paraneural vessels and the long artery. MACN is accompanied by its paraneural vessels and the basilic vein, so do LACN by its nutrient vessels and the cephalic vein. The distance range from the cutaneous nerve to its accompanying superficial vein is less than 1 cm, to its paraneural vessels is less than 0.4cm; and the distance range from the paraneural vessel to the superficial vein is about 0.3～1.2cm. Conclusions A flap pedicled with cutaneous nutrient vessels could be designed along a superficial vein. The type of flap might be different because of the different neurocutaneous blood supply. Some locally transferred venous flap might be a flap pedicled with neurocutaneous nutrient vessels.
