摘要
通过半薄及超薄切片,观察电烧伤后邻近烧伤局部,肉眼观无异常的动脉血管的微细结构变化,发现管壁细胞涂有空泡变生外,细胞及间质中现出分子气化引起的空泡。空泡在血管浅层汇聚,可将其表层的组织甚至是再生修复的组织掀起,剥脱。造成临床利用该段进行血管吻合术后,血栓形成的潜在危险。并讨论了气化发生的机理。
The microscopic changes of the arterial tissues which are near the burned area and no damges observed with naked eyes were examined with semi-and ultra-thin sections, In the blood vessel walls, there are vacuoles which are formed by molecular gasfication in the cell and mesenchyme besides, These vacuoles concentrate in the surface of the vessel walls, they can give rise to separation of surface even though the tissue is in the process regenerative repair, To do arterial anastomosis at this area can lead to the complication of thrombosis after clinical operation, This article has discussed the pathogenesis of gasfication.
