Abstract
The hepatopulmonary syndrome is defined by a triad including liver disease and/or portal hypertension, gas exchange abnormalities (arterial pO2 < 70 mmHg or alveolar— arterial gradient >20mmHg) and intrapulmonary vasodilatation. The mainstay of diagnosis of this syndrome is the detection of intrapulmonary vasodilatation. Contrast echocardiography (CE) and lung perfusion scanning (Tc99-MAA) are the current modalities utilized to detect intrapulmonary vasodilatation and to diagnose hepatopulmonary syndrome (HPS). This chapter will briefly review the HPS and focus on the use of CE in diagnosis as well as potential future diagnostic modalities.
