Abstract:
Objective To evaluate the effect of transcatheter hepatic artery embolization with lipiodol on perfused radiofrequency ablation (PRFA) on mini-porcine.Methods Ten Chinese mini-porcine were randomly divided into embolization group and control group (each n=5) .A standard PRFA with infusing cooling procedure was done in control group,while transcatheter hepatic artery embolization with lipiodol was done before PRFA in embolization group.CT and MR scan were performed after PRFA.Then a comparative analysis of the shape and volume of the lesions in the liver were performed.Resuits In both two groups,distinct spherical margin of the PRFA lesions was obtained.The minimal diameter was (31.76±3.43) mm in embolization group and (27.23±3.49) mm in control group (t=2.675,P＜0.05) .The average volume of the embolization group was (54.47±9.98) cm~3,while in the control group was (20.90±5.68) cm~3 (t=10.424,P＜0.05) .Conclusion Transcatheter hepatic artery embolization with lipiodol before PRFA can enlarge the ablation size of mini-porcine's liver.
