肘前部皮瓣微血管构筑的扫描电镜观察

THREE-DEMENSIONAL OBSERVATIONS OF MICROVASCULATURE OF HUMAN ANTICUBITAL FLAP BY SEM

作者运用扫描电子显微镜的方法,研究了一10岁童尸肘部皮瓣血管循环系统的ABS铸型。扫描电镜下,肘前部皮瓣的微血管构筑共由五层微血管网组成,(1)乳头层血管网,以见到垂直于皮肤表面走行的乳头毛细血管袢为特征,文中叙述了血管袢的五种结构形态。(2)乳头下层血管网:动脉与静脉相伴而行,其分支互相吻合,形成的血管网眼呈多角形。(3)真皮深层血管网:可见到二种形态的毛细血管球。(4)浅筋膜层血管网:以折扇形血管网为其特点。(5)深筋膜层血管网:血管呈干线型并行或交叉行走,水平发出的一些细小分支在干线血管周围吻合成血管网。本文论述了肘前部皮瓣微血管网与皮肤血运循环的关系以及在游离皮瓣移植中的意义。

ABS casts of the fine vasculature of human anticubital flap in a normal child(ten years old age)were studied by scanning electron microscopy(SEM).The anticubital flap contained five meshworks of capillaries,that is.(1).the meshwork of the papilla,mainly consisted of terminal loops of capillaries;(2).the meshwork of the subpapilla,being a thin layer;(3).the meshwork of the founs dermis,containing some capillary balls;(4).the meshwork of the superficial profascia,seen the leaflike rete of capillaries and(5).the meshwork of the profound fascia,the typical line vessels.The fine architecture of the anticubital flap vessels observed was discussed in terms of the physiology of blood circulation to the skin and the significance in the free flap transplantation.
