摘　　要：目的 探讨狭长窄蒂随意型皮瓣蒂的长宽比例与皮瓣成活面积的关系,为临床应用狭长窄蒂皮瓣提供理论依据.方法 将25只猪随机分成5组,每组5只,5组皮瓣蒂的长、宽比分别为0∶2,1∶2,2∶2,3∶2,4∶2,每个长宽比例的狭长窄蒂均携带5个不同面积的随意型皮瓣,分别为2 cm×2 cm、3 cm×3 cm、4 cm×4 cm、5 cm×5 cm、6 cm×6 cm,并依次命名为A、B、C、D、E,其中A瓣为B、C、D、E瓣的对照瓣,在每组每只猪的双侧背部均形成A、B、C、D、E皮瓣,顺序排列但两侧背部相反.对每组皮瓣进行大体观察、荧光色素钠染色、ECT血流测定、病理学表现和成活面积分析等.结果 ①狭长窄蒂随意型皮瓣和常规随意型皮瓣的成活过程和病理过程是一致的,皮瓣的成活过程并未因蒂部变窄变长而延缓.②当狭长窄蒂的长宽比例不变时,随着皮瓣面积的增加,皮瓣成活面积也随之增大,但达一定界限时皮瓣远端即发生坏死,而成活面积并未缩小.③当皮瓣大小不变,随着狭长窄蒂的长宽比例增加,皮瓣成活面积不受影响,但达一定界限时皮瓣远端即发生坏死,皮瓣成活面积缩小.结论 ①随意型皮瓣的蒂宽可远远小于瓣宽,蒂宽和瓣长比可远小于传统的比例.②随意型皮瓣的蒂部可以设计成狭长状,使整个皮瓣形似＂乒乓球拍＂,更利于皮瓣的旋转.③不同长宽比的狭长窄蒂所能携带的随意型皮瓣成活面积有其最大值,一定范围内增大皮瓣面积或蒂部的长宽比例不会导致皮瓣坏死.Objective To explore the relationship between the ratio of length to width of slender narrow pedicle and random flap survival area, and to provide a theoretical basis for the clinical application of slender narrow pedicle flaps. Methods 25 pigs were randomly divided into 5 groups, 5 pigs in each group. The ratio of length to width of slender narrow pedicle in 5 groups respectively was： 0∶2 , 1∶2 ,2∶2, 3∶2, 4∶2 . Every ratio＇s slender narrow pedicle was carrying five different size of random flaps,which were2cm×2cm（A）,3 cm×3 cm（B）,4 cm×4 cm（C）, 5 cm×5 cm（D）,6 cm×6 cm（E）,respectively. Flap A was control flap. In each group, flap A, B, C, D and E were created in each pigs＇bilateral back. The order in both sides back is contrary. The flaps were evaluated with the general observation, fluorescence examination, blood flow ECT test, pathological expression and computerized analysis of survival area. Results ① The living process and pathologic process of traditional flap and slender narrow pedicle flap were consistent. It could not postpone the flap living process when the flap pedicle became long and narrow. ② When the ratio of the length to width of the slender narrow pedicle was constant, along with the flap area increased, the flap survival area also increased, but when the flap reached a certain area , the distal flap would necrosis, the flap survival area would not reduce. ③ When the flap size remained unchanged, along with the ratio of the length to width of the slender narrow pedicle increased, the flap survival area was not affected, but when the ratio of the length to width of the slender narrow pedicle increased to a certain limit, distal flap would necrosis, the flap survival area would reduce.Conclusions ① Pedicle width of random flap can be much smaller than flap width. The ratio of pedicle width to flap length is far less than traditional ratio. ② The pedicle of random flap can be designed as slender shape, so that the whole flap looks like ＂pingpang bat
