Aims To construct in vitro models of normal uterine arterialvascular network through vascular corrosion casting andex-plore their characteristics and clinical significances.Methods Three sets of uterus，vagina and bilateral adnexawere peffused and cast via uterine artery and ovarian artery，using 25，20 and 1 5％chlorinated poly vinyl chloride，respectively，and constructed into models one，two and three ofthe uter-ine arterial network correspondingly.followed byobserving their characteristics. Results There existedimportant simi-larities and differences among the three modelsin display-ing uterine arterial network：in model one，theuterine arte-rial trunk，its branches and partial spiral arterieswere sharp-ly demonstrated except the tiny ones；model twofurther displayed the communicating branches betweenbilateral spiral arteries，the arterial v&,cular network of ovarianartery and the anastomoses between the arterial blood supply ofuterus and ovaries；model three presented the tiny branch-es，especially the obvious communicating branches，the completearterial Vsscular network of ovary and fallopian tube andanastomoses between them.Conclusions A pan-orama ofthe uterine arteriaI vasular network is obtained under organic combination of the three models,which is surely promising for clinical teaching，selections of different approaches andinterventional therapy in obstetrics and gy-necology.
