碘化油肝动脉栓塞对灌注型射频消融的影响:实验研究

目的观察碘化油肝动脉栓塞对灌注型射频消融的影响。方法中华小型猪10头,随机分为栓塞组与对照组。对栓塞组先行肝动脉碘化油栓塞再行灌注型射频消融,对照组仅行灌注型射频消融。消融后即刻行CT、MR扫描,之后处死实验猪取肝脏观察,比较凝固性坏死灶的形态、体积。结果栓塞组与对照组均可见边界清楚的圆形或椭圆形凝固性坏死灶,栓塞组消融灶最小径为（31.76±3.43）mm,对照组为（27.23±3.49）mm,两者间差异有统计学意义（t=2.675,P〈0.05）;栓塞组消融灶平均体积为（54.47±9.98）cm3,对照组为（20.90±5.68）cm3,栓塞组消融灶体积为对照组的2.6倍,两组间差异有统计学意义（t=10.424,P〈0.05）。结论灌注型射频消融前行动脉栓塞可有效地扩大射频消融灶的范围。

Influence of hepatic artery embolization with lipiodol on perfused radiofrequency ablation: An experimental study

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 ...
