我们在一具男尸的心脏解剖中、发现下腔静脉口处有一个由细丝构成的网状的单片状结构,并以钢丝附着在下腔静脉口的前壁和后壁上,处于前后位,其走行方向与前后室间沟起端连线的走行方向大致相当,将下腔静脉口分隔成左右大致相等的两个口.整个网状的片状结构长23mm,最宽处9mm.最窄处6mm.细丝的平均直径为0.31mm.网眼大小不等,形态不规则. In the anatomy of a male corpse, we found that there was a net-like monolithic structure of filaments in the mouth of the inferior vena cava and was attached to the anterior and posterior walls of the inferior vena cava by a wire, Bit, and its direction of travel is roughly the same as the running direction of the ditch connecting the anterior and posterior chambers, dividing the inferior vena cava into about two ports of about the same size.The entire reticular lamellar structure is 23 mm long and 9 mm wide. The narrowest place 6mm. The average diameter of the filaments is 0.31mm. Mesh size range, irregular shape.
