Clinical study on f ultrasound guided radiofrequency ablation in the treatment of primary hepatic carcinoma

Objective To observe the therapeutic effect of ultrasound guided radiofrequency ablation in the treatment of primary hepatic carcinoma.Methods Under the guidance of B-ultrasonography,radiofrequency electrode needle were punctured into liver tumor percutaneously,and the tumor was impaired in situ.Results Of 55 lesions in 46 patients,23 were of a diameter of less 3.5,among which,20 were totally impaired,with an ablation rate of 86.96%;15 were of a diameter of 3.5-8 cm,among which,11 were totally impaired,with an ablation rate of 733.33%;and 17 were of a diameter of more than 8cm(8 tumors had a diameter of more than 10cm),among which,12 were completely impaired,with an ablation rate of 70.59%.cm.Conelusion Percutaneous radiofrequency ablation is a safe and effective meathod in the treatment of primary liver cancer.
