摘要
观察了15具(30例)成人尸体的桡神经浅支的营养动脉及其来源动脉的数目、外径等。平均每条神经有3.47±0.22支营养动脉,外径平均0.23±0.07毫米。营养动脉的来源动脉,直接由桡动脉发出者占17.31±3.71%;间接从桡动脉的分支发出者(主要是桡侧返动脉、桡侧伸腕肌支和桡动脉的皮支等)占82.69±3.71%。除桡动脉外,其余来源动脉的外径平均为0.64±0.03毫米。观察结果表明,以来源动脉为蒂,作为桡神经浅支移植的吻接血管是可行的。
The blood supply of the superficial branch of the radial nerve was studied in 15 adult cadvers (30 sides). The number of nutrient artery passing to the superficial branch of the radial nerve averages 3.47±0.22. The mean outer diamiter is 0.23±0.07 mm. The original arteries, from which the nutrient arteries originate, come directly and indirectly from the radial artery in 17.31±3.71% and 82.69±3.71% respectively. The latter include the radial recurrent artery, muscular branch of the extensor carpi radialis and other cutaneous and muscular branches from the radial artery. The outer diameter of the original artery averages 0.64±0.03 mm. Our results indicate that original artery of the nutrient artery, supplying the superficial branch of the radial nerve, is ideal for a free vascularized nerve graft.
