摘要

目的 研究围肝门部门静脉和胆管的变异形式,并确定两者之间的关联。  方法 采用连续100例低位梗阻型黄疸患者的MDCT的数据,利用其薄层DICOM格式的图像使用Intrasense Myrian工作站进行肝脏、门静脉和胆管模型的三维重建。在计算机三维模型上研究门静脉和胆管的变异形式。   结果 所有入选病例均成功进行肝脏、门静脉和胆管模型的三维重建,图形显示清晰且可在工作站上任意组合显示和任意旋转观察。围肝门部门静脉总体的变异率为21%,胆管的总体变异率为36%。门静脉正常组(n=79)与门静脉变异组(n=21)比较,胆管变异率分别为30.4%和57.1%(P<0.05),组间差异具有统计学显著意义。   结论 围肝门部门静脉变异者胆管变异率升高,计算机3D重建是研究肝脏脉管解剖的优良工具。

Abstract

Objective  To investigate the relationship between perihilar portal vein anatomy and perihilar biliary duct anatomy. Methods The research involved continuous 100 low-part obstructive jaundice cases. Each case accepted MDCT scan. The researcher reconstructed 3-dimensional models of liver, portal vein and biliary ducts for each case using Intrasense Myrian software. The detailed anatomy of portal vein and biliary ducts was observed in these computed 3D models. Result All involved cases were constructed successfully. The liver, portal vein and biliary tract models could be combined and rotated freely. The total variation rate of perihilar portal vein was 21% and of the biliary ducts was 36%. The biliary tract variation rate in portal vein normal anatomy group (n=79) and portal vein variation group was 30.4% and 57.1%, respectively (P<0.05). Conclusion The perihilar portal vein anatomical variations may predict more biliary tract variation. The computed 3-dimensional reconstruction is an effective tool to investigate the anatomy of liver vessels.
