Conclusions the length and caliber of the vessel pedicle of the hypothenar flap fit the demand of the microsurgical anastomosis and can he applied in freely transplantation ; the flap ' s construction and vessel caliber are similar to the finger and suitable for repairing ventral defect of the finger 结论小鱼际皮瓣血管蒂的长度口径符合显微外科的要求，可用于游离移植；皮瓣结构、血管口径与指部相当，是修复指腹软组织缺损较理想的方法。
