CONTEXT Hepatopathies can significantly influence both veins and arteries, these changes may cause some cutaneous stigmas, such as spider angioma (SA) and some systemic vascular changes, such as those observed in hepatopulmonary syndrome (HPS). Based on this common pathophysiological root we can assume that the SA can be skin markers of HPS. OBJECTIVE The objective of this study is to assess ...

PURPOSE To evaluate surfactant protein A levels in an hepatopulmonary syndrome rat model. To date, there have been no studies aimed at evaluating surfactant levels in the setting of cirrhosis or hepatopulmonary syndrome. METHODS A total of 35 rats were divided into control, sham, and experimental HPS groups. We evaluated surfactant protein A levels in rats and the experimental model designed ...

Hepatopulmonary syndrome (HPS) is a clinical threesome composed of liver disease, intrapulmonary vascular dilatation (IPVD) and arterial gas abnormalities. Its occurrence has been described in up to 32% of cirrhotic candidates for liver transplantation. It also affects non-cirrhotic patients with portal hypertension. Its pathogenesis is not well defined, but an association of factors such as im...

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPHTN) are complications of portal hypertension and cirrhosis. Their pathophysiological mechanisms clearly differ. HPS is characterized by a defect in arterial oxygenation induced by pulmonary vascular dilatation. In contrast, PPHTN is predominantly due to excessive pulmonary vasoconstriction and vascular remodeling, but is rarely ...

It is now clear that hepatopulmonary syndrome (HPS) may occur and contribute significantly to gas exchange abnormalities in the setting of other cardiopulmonary abnormalities. Since there is no gold-standard diagnostic test for HPS, diagnosis rests on documenting arterial oxygenation abnormalities resulting from intrapulmonary vasodilatation in the setting of liver disease. Retrospective studie...

Pulmonary syndromes in the setting of hepatic disease with portal hypertension include portopulmonary hypertension (POPH), hepatopulmonary syndrome (HPS) and hepatic hydrothorax. POPH is defined as pulmonary arterial hypertension with portal hypertension in the absence of other causes of pulmonary arterial hypertension. HPS is a defect in arterial oxygenation as a result of pulmonary micro vasc...

Hepatopulmonary Syndrome (HPS) is a potential complication of chronic liver disease and is more commonly seen in the adult population. Caroli Syndrome is a rare inherited disorder characterized by intrahepatic ductal dilation and liver fibrosis that leads to portal hypertension. In children with liver disease, HPS should be considered in the differential diagnosis of prolonged, otherwise unexpl...

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...

Background and Aim: Hepatopulmonary syndrome (HPS) is defined as the presence of liver disease in association with intrapulmonary vascular dilatation and arterial hypoxemia. This work aimed at evaluation of hepatopulmonary syndrome in Egyptian patients with HCV-related chronic liver disease. Patients and Methods: This cross-sectional study included sixty patients with HCV-related chronic liver ...

Although liver transplantation (LT) is the only effective treatment option for hepatopulmonary syndrome (HPS), the post-LT morbidity and mortality have been high for patients with severe HPS. We performed post-LT embolotherapy in a 10-year-old boy who had severe type I HPS preoperatively, but he failed to recover early from his hypoxemic symptoms after an LT. Multiple embolizations were then su...
