Portopulmonary hypertension and hepatopulmonary syndrome.
The clinically and pathophysiologically distinct entities of portopulmonary hypertension and hepatopulmonary syndrome occur in a substantial proportion of patients who have advanced liver disease of different causes. These disorders are notoriously underdiagnosed, but they have a substantial impact on survival and require focused treatment. Abnormal intrapulmonary vascular dilatation, the hallm...
متن کاملHepatopulmonary syndrome following portopulmonary hypertension.
Portopulmonary hypertension (PPHTN) and hepatopulmonary syndrome (HPS) are distinct clinical entities that may accompany liver disease. While PPHTN and HPS have been infrequently described as occurring in the same patient, to the present authors' knowledge, the order of occurrence has always been the initial onset of HPS, with pulmonary hypertension developing either concurrently or subsequentl...
متن کاملPortopulmonary hypertension and hepatopulmonary syndrome: a clinician-oriented overview.
Liver disease and portal hypertension can be associated with pulmonary vascular complications, including portopulmonary hypertension (POPH), characterised by an elevated mean pulmonary artery pressure secondary to an increased pulmonary vascular resistance, and hepatopulmonary syndrome (HPS), characterised by hypoxaemia due to pulmonary vasodilatation and shunting. Although clear diagnostic gui...
متن کاملTransition from Hepatopulmonary Syndrome to Portopulmonary Hypertension: A Case Series of 3 Patients
Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPHTN) are the two major pulmonary vascular complications of liver disease. While HPS is characterized by low pulmonary vascular resistance, PPHTN is defined by the presence of elevated pulmonary vascular resistance. Given these seemingly opposing pathophysiologic mechanisms, these conditions were traditionally felt to be mutually ...
متن کاملThe pulmonary involvement in portal hypertension: portopulmonary hypertension and hepatopulmonary syndrome.
Pulmonary abnormalities are common in patients with advanced chronic liver disease. Two distinct syndromes strictly related to the presence of portal hypertension, but clearly different from a pathophysiologic point of view, have been identified. Portopulmonary hypertension, characterized by an increased pulmonary arterial pressure, is due to a progressive arteriolar vasoconstriction induced by...
