摘要:

目的 探讨胎儿全身动脉系统数字化三维模型的构建方法及其意义。  方法 采用“环氧树脂-氧化铅”填充剂对1例33周新鲜引产正常胎儿标本行全身动脉灌注并铸型,然后行64层螺旋CT薄层扫描采集二维图像数据,利用Mimics重建胎儿全身动脉系统数字化三维模型。   结果 基于CT原始数据,利用 Mimics 15.0软件成功构建出胎儿全身动脉系统数字化三维模型。重建得到的模型立体感强,三维效果逼真,与胎儿全身动脉血管铸型一致性高,可以清晰再现胎儿动脉主干及其分支的形态结构,且可进行任意缩放、任意角度旋转观察。  结论 胎儿全身动脉系统数字化三维模型的构建能够全面展示胎儿全身的各级动脉,为胎儿血管的后续研究提供了良好的支撑平台;该模型还可为宫内手术及宫内输血等提供解剖支持。

Abstract:

Objective To explore the method and significance of reconstructing digital three-dimensional models of the fetal whole-body arterial system.    Methods    One case of a fresh induced labor normal fetal specimen(33 weeks)was infused with epoxy resin-lead oxide and then casted, the 64-slice spiral CT thin layer scanning data of the casting specimens were used to reconstruct three-dimensional models of the fetal whole-body arterial system by Mimics software.  Results    Using the Mimics 15.0 software, the digital three-dimensional models of the fetal whole-body arterial system could be successfully reconstructed based on CT data. The three-dimensional models are realistic and stereoscopic, showing morphological structures of its fetal main artery and its branches clearly, which are highly consistent with the fetal whole-body arterial casting specimens. The three-dimensional models can not only be zoomed in or out, but also be revolved freely for better observation of fetal arterial vessels.    Conclusion    The digital three-dimensional models of thefetal whole-body arterial system can fully display the fetal arterial vessels. It is a good support platform to usedigital three-dimensional models to study fetal vessels, which serves as an anatomical support for intrauterine virtual surgery and intrauterine virtual surgery and intrauterine blood transfusion.
