摘　　要：背景: 双下腔静脉畸形临床上罕见, 多在尸检中发现, 自 1940 年 Adachi首次描述该畸形以来, 不断有文献报道,但几乎所有文献都在二维图像上进行描述, 目前尚无以三维动态图像展示双下腔静脉畸形。目的: 观测虚拟中国人男性Ⅲ号双下腔静脉连续横断面的走行, 建立双下腔静脉的可视化数字模型。设计: 以虚拟中国人男性Ⅲ号数据集为观察对象, 重复测量设计。单位: 南方医科大学南方医院创伤骨科和解剖学教研室。材料: 实验于 2006-02/05 在南方医科大学解剖实验室完成。数据来源为南方医科大学国家“八六三”虚拟中国人项目课题组采集的“虚拟中国人”男性Ⅲ号数据集, 该数据集共有 8 952 个层面, 连续层厚为 0.2 mm, 提取第 2 600 ～3 660 张图像作为断层观察和重建的数据来源。方法: 应用“虚拟中国人”男性Ⅲ号数据集, 在薄层断面图像上观察双下腔静脉结构, 应用 Amira 3.1(TGS)软件对双下腔静脉进行计算机三维重建并立体显示。主要观察指标: 虚拟中国人男性Ⅲ号薄层断面图像和三维重建图像观察结果。结果: 在虚拟中国人男性Ⅲ号薄层断面图像上清楚地显示了双下腔静脉的结构, 重建的数字化模型可准确的反映双下腔静脉的解剖学结构特点。结论: 虚拟中国人男性Ⅲ号数据集能够提供完整精确的双下腔静脉解剖。BACKGROUND：Double inferior vena cava （DIVC）, usually found at routine autopsies, is rare in the clinic. It has been described in numerous reports over the years since Adachi first depicted it in 1940. But all these reports were based on two-dimensional （2D） observation, and no three-dimensional and animated images reported. OBJECTIVE： To observe and establish the digital visible models of the structure of DIVC of the Virtual Chinese Human Male （VCH-M） Ⅲ.DESIGN： Repetitive measurement design by taking VCH-M Ⅲ as the subjects.SETTING ： Department of Traumatic Orthopedics and Anatomy, Nanfang Hospital Affiliated to Southern Medical University.MATERIALS： The experiment was conducted in Southern Medical University from February 2006 to May 2006. The cross-sectional images of fresh tissues from VCH-M Ⅲ dataset were reviewed and 1 060 serially-sectioned slices of VCH-M Ⅲ, from the 2 600th slice to the 3 660th were taken as the source for the 3D models in our study.METHODS： Cross-sectional images of fresh tissues from the VCH-M Ⅲ dataset were reviewed and the structures of the DIVC were confirmed on a section-by-section basis. 3D computerized reconstructions of DIVC and its adjacent structures were generated from these data using Arnira 3.1 （TGS） imaging software.MAIN OUTCOME MEASURES： Cross-sectional images and 3D reconstruction of VCH-M Ⅲ.RESULTS： The cross-sectional images of the VGH-M Ⅲ could fairly display the main structure of DIVC. The digitized model of brachial plexus offers unique insights into the abnormity anatomy of DIVC.CONCLUSION： The VCH-M Ⅲ dataset can provide complete and accurate data of DIVC.
