Abstract

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.
