Abstract:

Objective　To measure related parameters of the puncture channel of simulated direct intrahepatic portacaval shunt (DIPS) adopting 64-Slice spiral CT, and provide clinical guidance.　Methods　39 healthy volunteers, and 16 cases with cirrhosis underwent the upper abdomen 64-MSCT scan. The puncture points about 1cm and 2cm under the left and right portal branches, and that connected to intermediate retrohepatic segment of inferior vena cava were measured and scored according to Child-Pugh grades. In order to offer clinical applicable information for DIPS, the smart tracking technology (Smart Prep) were used to scan and further process on the GE ADW4.2 workstations.　Results　There was no significant difference between healthy volunteers and cirrhosis patients for the internal diameters of the left and right branches of portal vein under Child-Pugh grade. The shortest distance appeared between the left branch of portal vein and inferior caval vein.　Conclusions　For obtaining puncture parameters, 64-MSCT is valuable. This study demonstrates the appropriate length and type of the stents.
