Clinical application of ultrasound-guided Argon-Helium targeted ablation in treatment of liver tumor / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the effect and clinical value of ultrasonography-guided Argon-Helium targeted ablation on treatment of liver tumor.Methods By means of ultrasound inducing,217 patients of liver tumors were selected for percutaneous Argon-Helium targeted cryoablation.Results All of liver hemangioma shrank in different degrees after cryoablation; 12 cases of small hepatic cancer were followed up for over one year,the one-year survival rate was 83.3% (10/12). 82.1% (165/201) advanced patients became better and clinical symptom ameliorated.One hundred and seventy-five cases of advanced patients were followed up for over one year,the one-year survival rate was 69.7% (122/175).The common complications after Argon-Helium cryoablation treatment were hemorrhage( 3.7% ,8/217), pleural effusion( 2.8% , 5/217). Conclusions Ultrasound-guided Argon-Helium targeted ablation in treatment of liver tumor is simple,safe and effective.
