足内侧皮肤及浅、深筋膜血管构筑的扫描电镜观察

用ABS丁酮溶液血管铸型方法,研究足内侧皮肤及浅、深筋膜内血管配布规律,并观察了皮纹内微血管的形态学特点。本文对不同皮肤区域内的皮肤乳头层血管网和血管襻具有显著不同特点进行了讨论。并指出,足内侧区皮肤及浅、深筋膜内的5层血管网,是由来自直接皮肤动脉和间接皮肤动脉进入该区的上升支所发出的5级分支形成的。

MICRO-VASCULAR STRUCTURE OF THE SKIN AND SUPERFICIAL AND DEEP FASCIA IN THE MEDIAL PART OF FOOT UNDER SCANNING ELECTRON MICROSCOPE

The fresh cadavers were injected with A. B. S into the popliteal arteries. We have studied the micro-vascular structure of this skin area under scanning electron microscope. There are 5 layers of the vascular network in this skin area. They were formed by the small branches coming from either the direct or indirect cutaneous arteries. The 5 layers are as follows: The capillary network of the papillary layer. The vascular network of the subpapillary layer. The deep dermal network. The network in the subcutaneous tissue. The network in the deep fascia tissue. It is clear that each layer of the vascular network has it's -own special character.
