临床上每个皮瓣的取舍,都是要以人体浅表血管的分布、走行、营养范围及供血血源为依据,特别是近年巨微型皮瓣的应用。为此,对研究轴型皮瓣的轴心血管,如轴心动脉或轴心静脉的血管蒂的定位、其外径、蒂长、轴向、供血范围、与其相邻血管的吻合、区域性循环、定位标志性结构等问 Clinically, the choice of each flap, are to the distribution of the human superficial blood vessels, walking, nutrition and blood supply as the basis, especially in recent years, the application of micro-flaps. To this end, the axial axis of the axial skin flap research, such as axial artery or axial vein pedicle positioning, its diameter, pedicle length, axial, blood supply range, with its adjacent blood vessels anastomosis, regional Circulation, positioning and other landmark structure asked
