本研究探讨之间的关系生存的面积和长度/宽度比细长窄状皮瓣的随机评估其临床安全性。25头猪被随机分为五组每组(n = 5)。激素狭窄的长度/宽度比率在所有5个组0/2 (cm), 1 / 2 (cm), 2/2 (cm), 3/2 (cm),和分别4/2 (cm),这些创建五个随机皮瓣大小不同的两侧的每个猪(襟翼[控制]:2厘米×2厘米;B: 3厘米×3厘米;C: 4厘米×4厘米;D: 5厘米×5厘米;和E: 6厘米×6厘米)。是“传统”皮瓣皮瓣。所有皮瓣生存领域被一般的观察,评价静脉注射荧光染料,血液流动等(发射计算机断层扫描)分析、和组织病理学检查。传统皮瓣内的临床病程和病理过程(瓣)和细长窄蒂皮瓣是一致的。 An increasing flap area and a constant length/width ratio, or vice versa, preserved the area of graft survival. However, when the flap area reached a certain limit, the distal flap necrosis without decreasing the overall flap survival area in the same group; when the length/width ratio reached a certain limit, the distal flap necrosis with decreasing the overall flap survival area in the same group. The width of the pedicle can safely be significantly smaller than the width of the flap, and the flap pedicle can be designed to be slender. This type of pedicle facilitates flap rotation. However, there is a maximum flap survival area that the slender narrow pedicle can support.
