Experimental study of selective portal vein embolization with the mixture of ZT glue and lipiodol / 中国医师杂志

ABSTRACT

Objective To evaluate the feasibility of Selective Portal Vein Embolization(SPVE)in rabbits with the mixture of ZT glue and Lipiodol.Methods Sixteen white New Zealand rabbits were randomly divided into 2 groupsGroup A,ZT glueLipiodol(12)mixture and Group B Lipiodol group.SPVE of left branch was performed in each group under digital subtraction angiography.The distribution feature of the embolic agents and the histopathology of liver in each group were observed.The weight ratio of the right lobe to the whole liver at the 30th day after SPVE were recorded and analyzed.Results Permanent embolization were occurred in group A.Recanalization was appeared in group B.Atrophy of the embolized lobes and compensatory hypertrophy of none-embolized lohes was,observed..The weight ratio of the right lobe to the whole liver Was 69.41±5.10% in group A.There was statistical difference between these two groups(P＜0.05).Conclusion There were permanent embolization after SPVE with the mixture of ZT glue and lipiodol.SPVE induced atrophy of the embolized lobes of liver and compensatory hypertrophy of none-embolized lobes.
