摘　　要：目的 探讨三维重建技术在邻近皮瓣移植中的应用价值.方法 采用美国GE 64排螺旋CT机对11例患者下肢进行CT血管造影（CTA）,利用三维软件分别重建出骨、肌肉、筋膜、皮肤与血管,并对血管进一步分割,构建出单支血管及其分支三维图像,并对所构建的三维图像进行单独显示与组合显示.结果 11例患者经下肢进行CTA扫描后不仅能在病损周边显示三级以下的血管,并且能显示局部的具体分布状况,为邻近皮瓣的临床个性化设计提供准确的血管解剖学基础.结论 对于邻近皮瓣基础研究和临床手术的个性化设计三维重建方法是一种很好的辅助方法.Objective To investigate the application of the three-dimensional reconstruction for the random flap.Methods The bones,muscles,fascia,skin and vessels in eleven patents were reconstructed by the MIMICS 10.01 CT angiography （CTA） scanning,and the single artery and its branches were gained by the subdivision of the vessels.3D-images were shown respectively and jointly.Results Arterial reconstruction images were clearly displayed by 3D workstation CTA and if they were combined with the original cross-sectional images and vessel analysis software,they were able to accurately evaluate the location,range,degree of artery,the distal outflow tract.The vessels and soft tissue displayed in the software could show detailed distribution of the vessels in one region and this could provide the accurate anatomical basis for the random flap and the design of the operation.This method could easily meet the preoperative design demands and also had the guiding significance for postoperative evaluation.Conclusions The method of 3D-reconstruction is very good for studying the random flap and the design of the operation.
