Abstract    Objective    To explore the clinical value of the abdominal medical Image three-dimensional visualization system (MI-3DVS) in the diagnosis and treatment of abdominal aortic aneurysm(AAA). Methods    The data of 13 cases with AAA provided by 64-slice spiral computerized tomography (CT) is collected and adjusted by DICOM Viewer before reconstructed. Then the adjusted datum are segmented and reconstructed in three-dimensional (3D) models by the MI-3DVS which has been exploited ourselves. The 3D models are classified and measured to select the preferable operation. Finally, the 3D models are imported into the Freeform Modeling System to study on virtual surgery of vascular prosthesis replacement and endovascular exclusion for AAA and to assess the clinical value of the MI-3DVS. Results The 3D models of 13 cases have characteristic of realistic, stereoscopic and clear in interrelationship. They are helpful to classification accurately. It is showed that the effect of the management of the virtual surgery on AAA is the same as that of the surgical interference. Conclusion    The MI-3DVS contribute to preoperative evaluation and selecting preferable surgical interference. Furthermore, we can also get more familiar with the procedure of the surgical interference, save our time and improve our surgical skills. At the same time, the virtual surgery can strengthen the doctor-patient communication.
