Microbubbles in the Pulmonary Artery Generated During Experimental Hepatic Radiofrequency Ablation Is Correlated with Increased Pulmonary Arterial Pressure

Microbubbles were detected in the pulmonary artery during hepatic RF ablation both during maintained and interrupted hepatic inflow. A strong association was found between microbubbles in the pulmonary artery and increased MPAP. The clinical implications of our findings are to be determined.
