INFLUENCE OF TRANSCATHETER HEPATIC ARTERY EMBOLOZATION USING IODIZED OIL FOR RADIOFREQENCY ABLATION OF HEAPTIC NEOPLASMS

DU Xi lin,MA Qing jiu,GAO De ming,et al.Department of surgery,Tangdu hospital,Fourth Military Medical University,Xi'an 710038,China).  
Objective To observe the effect of iodized oil for radiofrequency thermal ablation(RFA) of hepatic neoplasms by using a cluster array of ten separate electrodes.Methods Clinic patients divided into 2 groups,group A transcatheter hepatic artery embolization,group B didn't transcatheter hepatic artery embolization,and all radiofrequency ablation of hepatic neoplasms.Result The time of RFA to group A was 9±2.1 minutes,the diameter of necrosiswas 5.3±1.4cm,the time of RFA to group B was16±4.6 minutes,the diameter of necrosis was 3.5±1.8cm( P 0.01).Conclusions These findings suggest that radiofrequency thermal ablation of hepatic neoplasms with transcatheter hepatic artery embolization using iodized oil might have safetyand synergic effect.
