摘要
本文采用墨汁灌注透明、组织切片及微血管铸型等方法,在显微镜、图像分析仪、扫描电镜下,观测青年男性新鲜尸体腹部皮瓣的血管。人腹部皮瓣内血管支的走行呈三阶梯式,皮动脉主干和主支走在浅筋膜深层,其分支及末支在真皮网状层中份形成微血管吻合,由吻合发出分支,在乳头下层再形成微血管网。皮瓣内血管网的分布,集中在深筋膜、浅筋膜、真皮深层、乳头下层和乳头层。上述3、4层血管网之间有乏血管网区。腹部皮瓣各区之间面积分数(Aa)和各区相应各层之间的血管计数,差异均无显著性。本文还讨论了切取腹部皮瓣和皮片的有关问题。
A study on abdominal skin flaps of the fresh cadavers of young men under the operation, light and scanning electron microscope, and MAS image analysis system has been made. Methods include Chinese ink, ABS or methyl methacrylate injection and histological slides, transparent specimens as well as casts preparation.
The course of the vessels in the human abdominal skin flap is in the 'three steps form'. Trunks and main branches of the cutaneous vessels run in the deep part of the superficial fascia, their branches and terminals form anastomoses in the middle of the reticular layer of dermis, and branches from the anastomoses form microvascular network in the subpapillary layer. The vascular networks in the skin flap are concentrated in five layers: the deep fascial, superficial fascial, profund dermal, subpapillary, and papillary layers. Between the subpapillary and the profund dermal vascular networks, there is a layer devoid of vascular network and crossed by vascular arteries only. Therefore, this layer may be called as 'vascular network devoid area'. The differences of the area fraction (Aa) or number of vessels are not significant among various areas of the abdominal skin flap. Design in detaching the abdominal skin flaps and skin grafts is discussed.
