Title: Effect of blunt hepatic trauma with percutaneous radiofrequency ablation by contrast-enhanced ultrasonography
Abstract: Objective To study the value of contrast-enhanced ultrasonography in evaluating the effectiveness of the treatment effect of blunt hepatic trauma by percutaneous radiofrequency ablation.Methods Sixteen pig-models with blunt hepatic trauma and active bleeding were created and evenly divided into therapeutic group and control group.Two dimensional gray ultrasound and contrast-enhanced ultrasonography were performed to detect the livers before and after the treatment of percutaneous radiofrequency ablation.The results were compared with pathologic findings.Results Active bleedings were found with contrast-enhanced ultrasonography in all cases instantly after liver injury.In the therapeutic group,after the first percutaneous radiofrequency ablation,active bleedings were detected by contrast-enhanced ultrasonography in only one case.And after the second percutaneous radiofrequency ablation,active bleeding disappeared in this case.Hemorrhages were not found by contrast-enhanced ultrasonography one hour after the treatment.In the control group,hemorrhages were still detected by contrast-enhanced ultrasonography one hour after the liver injury.Gross pathologic findings were consistent with the results of contrast-enhanced ultrasonography.Conclusion Contrast-enhanced ultrasonography is a credible method to evaluate the effectiveness of the treatment effect of blunt hepatic trauma by percutaneous radiofrequency ablation in real time.
