摘　　要：目的研究构建猪泌尿生殖系统动脉血管网模型,为人子宫动脉血管网模型的构建提供技术基础。方法2008年3月至8月于南方医科大学南方医院妇产科获取雌猪离体泌尿生殖系统标本(子宫、附件、阴道、膀胱及尿道)3套,配置20%、15%、10%的过氯乙烯作为填充剂,分别经子宫动脉、卵巢动脉及尿生殖动脉灌注,采用酸腐蚀法,观察不同浓度填充剂构建的猪泌尿生殖系统动脉血管网显示的效果。结果(1)用20%过氯乙烯作填充剂构建的模型可清楚显示子宫动脉、卵巢动脉及尿生殖动脉主干的走行、分布及各动脉之间的吻合支,但细小动脉分支难以显示。(2)用15%过氯乙烯作填充剂构建的模型可进一步显示细小动脉的分支血管网。(3)用10%过氯乙烯作填充剂构建的模型可更清楚显示局部组织致密的血管网结构及交通支吻合情况。结论20%过氯乙烯作填充剂显示的血管网适合对模型进行计算机图像重建,采用15%过氯乙烯填充剂适于制作动脉血管网铸型标本,10%过氯乙烯作填充剂适于构建局部动脉血管网模型并进行特异性研究。Objective To study the arterial network models of animal genitourinary system perfused by different concentrations of filler through vascular cast, laying foundation for the construction of uterine arterial vascular network model. Methods Collect three sets of female pigs＇genitourinary system specimens with uterus, annexs , vagina, bladder and urethral, and three different concentrations of chlorinated poly vinyl chloride were prepared for perfusion through the uterus arteries, the ovarian arteries and the urogenital arteries, then corrode them by acid, in order to analyse the expression of the blood vessels. Results （ 1 ） The 20% model purfused could clearly show the boles of the uterus arteries, the ovary arteries and the urogenital artery, but it was difficult to show the small arterial branches. （2）The 15% model purfused could further to show the branch network of tiny arteries. （ 3 ） The 10% moded purfused concentration could show the local fine structures and the communicating branches clearly. Conclusion The 20% model constructed by the high concentration of chlorinated poly vinyl chloride may be used for imaging reconstruction by computer. For constructing the arterial network cast the 15% model parfused may be used. The 10% model purfused can be used for constructing the local arterial vascular network so as to research into its speciality.
