CT guided percutaneous targeted argon-helium cryoablation for liver cancer / 中国普通外科杂志

ABSTRACT

Objective To study the method,effect and safety of percutaneous targeted argon-helium (cryoablation) for liver cancer. Methods Retrospective analysis of the clinical data was made on the 52 (patients) with primary liver cancer who were treated with argon-helium cryoablation. Results Following the treatment of the 52 (patients), there were no operative mortality or complications, such as rupture of liver,bleeding,biliary fistula,frostbite of skin,and metastatic implantalion or infection at the injection site.(Postoperatively), 5 patients developed pneumothorax and reactive pleural effusion, and 43 patients had a low-grade fever. The 1- and 2-year survival rates were 63.5 %( 33/52) and 36.5 %( 19/52)(respectively).After treatment, the AFP levels were significantly lower. Conclusions CT guided percutaneous targeted argon-helium cryoablation is a reasonable, safe, effcctive and mimimally invasive new therapeutic method for the treatment of liver cancer.
