Heat injuries of adjacent organs need to be considered when radiofrequency and microwave ablation procedures of hepatocellular carcinoma or hepatic metastases are performed, especially when the target lesion is in a subcapsular portion of the liver. Hydrodissection can be performed prior to radiofrequency or microwave ablation procedures in which the target lesion is in a subcapsular portion of the liver and adjacent to another structure, particularly the diaphragm. This technique creates a fluid layer thick enough to separate the nearby structures from the target lesion in the liver, providing thermal insulation around the ablation area. Moreover, if fluid (rather than CO2) is used, it improves the sonic window when the target lesion is not visible or only partially visible due to overlapping bowel, lung, or ribs.
