The use of contrast-enhanced ultrasonography in the intensive care unit for exclusion of active bleeding and detection of regional perfusion impairment in a transplanted liver.

The article discusses the use of contrast-enhanced ultrasonography (CEUS) at bedside to assess liver perfusion and exclusion of active bleeding after transcutaneous liver biopsy. The technique's enabling of quantification of microvascularization up to the capillary levels is mentioned. The detection of biopsy-induced perihepatic hematoma is also addressed.
