Percutaneous radiofrequency ablation for liver cancer located under the diaphragm / 介入放射学杂志

Objective To evaluate the feasibility and safety in the treatment of liver cancer located under the diaphragm with cool-tip radiofrequency ablation(RFA)percutaneously under CT guidance.Methods 20 patients with total 25 lesions were treated by CT-guided RFA with cool-tip electrode involving the induced necroses.The postoperative efficacy was evaluated by enhanced CT or MRI.Results 72% lesions were completely necrotized(18/25),28% lesions were majorly necrotized(7/25).No severe complications occurred. Conclusion CT-RFA with cool-tip electrode is effective and safe in treating liver cancer located under the diaphragm.
