Analysis of complication associated with Ultrasound-guided percutaneous RFA for hepatic cellular carcinoma / 中国医师杂志

ABSTRACT

Objective To evaluate the safety and effective of ultrasound-guide percutaneous radio frequency ablation (RFA).Methods Retrospectively analyze the incident,management and influence factors of complication of ultrasound-guide percutaneous RFA.Results From 2001 to 2011,536 patients with 762 lesions underwent RFA were enrolled in this study.Incident of RFA complication was 2.03％ (11/536),including 5 (0.92％) major complication.The complication covered fever (1 case),massive hydrothorax (2 cases),hydrothorax accompany with ascites (1 case),massive ascites (1 case),liver abscess (1 case),liver capsule hemorrhage (1 case) and hemothrorax (1 case).No RFA relate mortality was observed.According to logistics regression analysis,the liver function Child-Pugh grading was associated with the RFA complication (P =0.005).Conclusions Ultrasound-guide percutaneous RFA is a safe and effective local treatment approach for hepatocellular carcinoma.It's necessary to comprehensively think over the basic condition of patients and the characters of tumor such as tumor location,size and abutting organs.Nevertheless,an appropriate treatment plan and closely monitor during and after RFA are crucial.
