Influence of transcatheter hepatic artery embolization using iodized oil on radiofreqency ablation of hepatic neoplasms / 介入放射学杂志

ABSTRACT

Objective To observe the effect of iodized oil on radiofrequency thermal ablation (RFA) of hepatic neoplasms by using a cluster array of ten separate electrodes. Methods The patients were divided into 2 groups, group A with transcatheter hepatic artery embolization, group B without transcatheter hepatic artery embolization. All patients were undergone radiofrequency ablation of hepatic neoplasms. Results The time of RFA for group A was (9?2.1) minutes, showing the diameter of necrosis of (5.3?1.4)cm. The time of RFA for group B was (1.6?4.6) minutes demonstrating the diameter of necrosis of (3.5?1.8)cm (P
