Abstract:
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.
