Abstract:
Objective To evaluate the feasibility,efficacy and tolerability of ultrasound-guided percutaneous radiofrequency ablation(RFA) for treating malignant tumor in the caudate lobe.Methods A retrospective analysis was performed in the patients with malignant tumor in the caudate lobe treated by percutaneous radiofrequency ablation (RFA) from January 2009 to July 2016.The epigastric approach (EA),the intercostal approach (IA) and an approach combining EA and IA were used as the paths of puncture.Intraprocedural contrast enhanced ultrasound (CEUS) was used to evaluate the ablation effect.The enhancement of CT/MR was used as the gold standard to evaluate the ablation effect within 1 to 3 months after surgery.Technical success (TS),technique efficacy (TE),local tumor progression (LTP) and complications were documented.Results A total of 14 patients with 14 malignant tumors in the caudate lobe of the liver were included in this study.The EA,IA,and the approach combining EA and IA were used in 7,6,and 1 patient,respectively.Intraprocedural CEUS showed complete ablation in all cases.CT / MRI evaluation within 1 to 3 months after surgery showed that the complete ablation rate was 100％ (14/14).After a median follow-up of 15.5 months (interquartile range,3 55 months),2 patients had recurrence in other regions of the liver,there was no local tumor progression and no serious complications occurred in 14 patients.Conclusions Ultrasound guided RFA is a safe,effective and important mean for the treatment of malignant tumors in caudate lobe of liver.
