To construct in vitro models of normal uterine arterial vascular network through vascular corrosion casting and explore their characteristics and clinical significances.
Three sets of uterus, vagina and bilateral adnexa were perfused and cast via uterine artery and ovarian artery, using 25, 20 and 15% chlorinated poly vinyl chloride, respectively, and constructed into models one, two and three of the uterine arterial network correspondingly, followed by observing their characteristics.
There existed important similarities and differences among the three models in displaying uterine arterial network: in model one, the uterine arterial trunk, its branches and partial spiral arteries were sharply demonstrated except the tiny ones; model two further displayed the communicating branches between bilateral spiral arteries, the arterial vascular network of ovarian artery and the anastomoses between the arterial blood supply of uterus and ovaries; model three presented the tiny branches, especially the obvious communicating branches, the complete arterial vascular network of ovary and fallopian tube and anastomoses between them.
A panorama of the uterine arterial vascular network is obtained under organic combination of the three models, which is surely promising for clinical teaching, selections of different approaches and interventional therapy in obstetrics and gynecology.
通过血管腐蚀铸造技术构建正常子宫动脉血管网络的体外模型，并探讨其特征和临床意义。
通过子宫动脉和卵巢动脉分别灌注和铸造三组子宫、阴道和双侧附件，使用 25%、20%和 15%的氯化聚氯乙烯，相应地构建成子宫动脉网络的模型一、二和三，然后观察它们的特征。
三种模型在显示子宫动脉网络方面存在重要的相似和不同之处：在模型一中，子宫动脉干、分支和部分螺旋动脉得到了清晰的显示，除了微小的动脉外；模型二进一步显示了双侧螺旋动脉之间的交通支、卵巢动脉的动脉血管网络以及子宫和卵巢的动脉供血之间的吻合；模型三显示了微小的分支，特别是明显的交通支、卵巢和输卵管的完整动脉血管网络以及它们之间的吻合。
三种模型的有机结合可以获得子宫动脉血管网络的全景图，这对于妇产科的临床教学、不同方法的选择和介入治疗具有重要的意义。
