We concluded that:(1) the pedicle width was not the determinative factor of the survival length of random flap,and there was no direct ratio relationship between pedicle width and survival length;(2)Narrowing the pedicle of a random flap which can survive completely,transforming it into a kind of flap which ratio of length to width exceeds the limitation.
我们认为:(1)随意型皮瓣成活长度与皮瓣血流灌注压有关,蒂宽不是皮瓣成活长度的决定性因素,两者之间不存在直接比例关系。
