Hepatocellular Carcinoma (HCC) is a common cause of death in patients with cirrhosis. Radiofrequency ablation (RFA) is an evolving technology producescoagulation necrosis of tumor through local tissue heating. Currently, several typesof radiofrequency ablation generators and electrodes are available in the market-placetoday; one particular type (Radionics) has internal channel for cold saline flow forcooling around needle tip, and Radiotherapeutics (umbrella) have needle electrode with multiple expandable arrays at the tip. The aim of this work was to compareefficacy, safety and complications between internally cool-tip radiofrequency needleelectrode and expandable radiofrequency needle electrode in percutaneous ablation ofhepatocellular carcinoma. This study was carried out on44 HCC in forty patients; they were 33 males and 7 females with a male. In our study, the mean number ofsessions in RFA cool tip group was (2.05), versus (1.68) in RFA expandable group.The success rate in ablating HCCs was (86%) in RFA cool tip, and (82%) in RFA expandable. the over all survival rate in internally cooled electrode was (90%); at(33.16 months) versus (90%) at (33,62months) in expandable electrode group.
