RESUMO
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.
RESUMO
Objective To evaluate the clinical effects of CT guided percutaneous aspiration and sclerotherapy in treatment of hepatic cysts.Methods Sixty three patients with single(n=41)and muttiple(n= 22)hepatic cysts were undertaken CT guided pereutaneous aspiration and sclerotherapy with injection of absolute alcohol.Results Sixty three patients underwent follow-up for 3-15 months after the operation showing effective indexes as grade 0 for 4(6.39%),gradeⅠfor 8(12.69%),gradeⅡfor 23(36.51%)and gradeⅢfor 28(44.44%)cases.The total effective rate reached 93.61%.No serious complications occurred. Conclusion Sclerosing therapy with absolute alcohol is safe,economic,simple and effective for treating hepatic cysts.(J Intervent Radiol,2007,16:850-852)
