Objective To evaluate the influence of infusing salviate milttionrrhize via portal vein on the pressure of portal vein of cirrhotic patients(FPP).Methods 46 patients of fiver cirrhosis were included this stuby.All cases were pierced with guiding of ultrasound tape B a tube with locks into a branch of portal vein and their FPP was measured.Then 20ml salviate milttionrrhize mixed with 250ml glucose was infused via portal vein once daily for 2 weeks and measure FPP after the treatment.Results FPP declined a value from 8cm H2O(1 cm H2O=0.098 kPa)t026CnlH20.(P＜0.05).Conclusion The infusion of salviate milttionrrhize via portal vein can effectively decline FPP.
