Abstract:
Objective To investigate the effectiveness and safety of thermal ablation of patients with 3－5 cm hepatocellular carcinoma ( HCC ) under the assistance of ultrasound fusion imaging . Methods From December 2010 to December 2017 ,76 HCC patients with 78 medium‐size ( 3 －5 cm ) lesions who underwent radiofrequency ablation ( RFA ) or microwave ablation ( M WA ) were included in the study . Ultrasound fusion imaging was used to assist the ablation procedures and assess the technical success immediately ,then guided supplementary ablation . Contrast‐enhanced CT/M R was performed one month after ablation to assess the technique efficacy rate . T he complication ,local tumor progression ( L T P ) rate were followed up . Results According to the ultrasound fusion imaging evaluation ,24 lesions ( 30 .8% , 24/78) received supplementary ablation immediately during the ablation procedure . Seventy‐one of 78 liver tumors were evaluated to achieve 5 mm ablative margin while the other 7 liver tumors were not achieved . T here were no ablation‐related deaths ,and the major complication rate was 6 .6% ( 5/76 ) .T he technique efficacy rate was 100% ( 78/78) according to the contrast‐enhanced CT/M R one‐month later . Patients were followed up from 6 to 79 months with a median time of 22 months . L T P occurred in 4 lesions and the LT P rate was 5 .1% ( 4/78) . Conclusions With the assistance of ultrasound fusion imaging ,thermal ablation of medium‐sized HCC is effective and safe w hich could achieve a higher technique efficacy rate and a lower L T P rate .
