Abstract:
Objective To investigate CT examination in the evaluation of the percutaneous radio frequency ablation (RFA) in the treatment of hepatic carcinoma.Methods 50 cases of hepatic carcinoma (including primary hepatic cancer 36 and hepatic metastases 14) with 76 lesions treated by RFA associated with pre and post procedure data of CT follow up were analyzed retrospectively. CT examinations including plain and contrast enhanced CT scanning were carried out at 1 week and 3 weeks after the RFA, but sometimes with furthermore intermittent scanning at 3～6 months. Results Complete ablation of the tumors occurred in 49 lesions (64.5%) of 35 cases and incomplete ablation of tumors happened in 27 lesions (35.5%) of 18 cases. Among RFA treated 76 lesions, there were 9 with internal hemorrhage, 1 with abscess formation. 3 cases showed intraperitoneal bleeding; 6 cases demonstrated reactive pleural effusion and 1 case revealed with small amount of pneumothorx.Conclusions The contrast enhanced CT scanning provides a great diagnostic value for evaluation of the efficacy of hepatic tumor treated by RFA and also the local recurrence and complications.
