An in vitro Comparative Study of Gasification Induced by Radiofrequency Ablation in Different Tissues
摘要
Abstract
Objective To investigate the association between gasification and duration and power of radiofrequency ablation in porcine muscle and liver and compare the effects in these tissues in an in vitro study. Methods Radiofrequency ablation was performed on fresh muscle and liver tissue,and the maximum cross-sectional volume of gasification was used to compare the effects according to duration and power of ablation. The experiment was repeated three times,and data were averaged. Results Within a certain range,gasification volume increased significantly with increases in ablation duration and power (P < 0.05). Gasification volumes differed significantly between tissues (P < 0.05). The gasification volume was smaller in muscle than in liver at 15 W and 30 W,while the affected volume in muscle was greater than in liver at 45 W (P < 0.05). Conclusion Under conditions of the same duration and power,the gasification volumes were different in muscle and liver. Therefore,the power and time required for maximum gasification in different tissues may be different.关键词
