Through observation on the cast and perfused humen specimens, it was found that in some donor areas of skin flap the veins run loosely in compare with their arteris. The companionship of the axial artery and vein can be divided into 3 types: (1)One set of venous system, which runs loosely in company with the artery, such as the pedicle vessels in flaps of head and face areas; (2)Two sets of accompaned venous system, one of them did not accompany closely with the axial artery, as is the vessel in skin flaps of low abdominal areas; (3) Lack of accompanying venous system, as is found in the dorsal finger flaps. Based on these anatomical companionships of the veins with their arteries, when such flaps as mentioned above are adapted, it is preferable to take abroadened fascial pedicle in order to achieve a higher survival rate of skin flap transplantation.
