Objective   To offer clinical applicable information on morphology by means of measurement of the simulated puncture channel of the right portal branch at 1 and 2 cm and venae hepaticae intermediae and right hepatic veins at 1

2

and 3 cm in patients without liver diseases and those with cirrhosis Child-Pugh grade A and B.   Methods   Abdominal 64-MSCT scan was performed in 40 cases without liver diseases and 14 cases of cirrhosis after the test of the celiac levels of abdominal aorta was conducted by the smart tracking technology (Smart Prep). The data were processed for imaging on the GE ADW4.2 workstation.   Results   Significant difference was found between the normal group and cirrhosis Child-Pugh grade A and B groups

ФMHV1

ФRHV1 (P0.05). The diameter of the normal right hepatic vein at 1-2 cm and that of the middle hepatic vein at 1-2 cm decreased rapidly as compared with that of cirrhosis Child-Pugh grade A and B groups. There was also significant difference (P0.05) between the normal and cirrhosis Child-Pugh grade A and B groups in the simulated puncture channels of DMHV2-RPV1

DMHV3-RPV1

DMHV3-RPV2

and DRHV1-RPV1.   Conclusion   64-MSCT and the three-dimensional reconstruction may be an effective way for accurate measurement of the intrinsic liver vessels in vivo. The study of the simulated intrahepatic portosystemic shunt can help to choose the appropriate length and type of the stents.
