UNLABELLED Hepatopulmonary syndrome (HPS) is a pulmonary vascular disorder occurring as a consequence of advanced liver disease, characterized by hypoxemia due to intrapulmonary vascular dilatations. HPS independently increases mortality, regardless of the cause or severity of liver disease. Liver transplantation (LT) improves survival in HPS. We present the largest consecutive series of HPS pa...

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...

The hepatopulmonary syndrome (HPS) results from intrapulmonary vasodilation in the setting of cirrhosis and portal hypertension. In experimental HPS, pulmonary endothelial endothelin B (ET(B)) receptor overexpression and increased circulating endothelin-1 (ET-1) contribute to vasodilation through enhanced endothelial nitric oxide synthase (eNOS)-derived nitric oxide (NO) production. In both exp...

aim : this study evaluated the association between serum endothelin- 1 level and symptoms, clinical examination, laboratory and cardio-respiratory parameters, in patients with cirrhosis compared to controls. background : cirrhosis is associated with significant portal, pulmonary and systemic vascular abnormities. recent studies have suggested that endothelin -1 may have a significant role in th...

Hepatopulmonary syndrome (HPS) is a serious complication of end-stage liver disease, which is characterized by hypoxia, intrapulmonary vascular dilatation, and liver cirrhosis. Liver transplantation (LT) is the only curative treatment modality for patients with HPS. However, morbidity and mortality after LT, especially in cases of severe HPS, remain high. This case report describes a patient wi...

BACKGROUND The macro-aggregated albumin lung perfusion scan (99mTc-MAA) is a diagnostic method for hepatopulmonary syndrome (HPS). GOAL To determine the sensitivity of 99mTc-MAA in diagnosing HPS, to establish the utility of 99mTc-MAA in determining the influence of HPS on hypoxemia in patients with concomitant pulmonary disease and to determine the correlation between 99mTc-MAA values and ot...

BACKGROUND Hepatopulmonary syndrome is reported to occur in 4% to 32% of the patients with chronic liver disease and is associated with poor liver function and shortened patient survival before and after liver transplantation. AIMS To assess the frequency of hepatopulmonary syndrome in Brazilian patients with decompensated chronic liver disease and to investigate its impact on patient surviva...

Hepatopulmonary syndrome is a rare complication of liver disease and portal hypertension. It has not been previously described in medical literature Nigeria. We report this case 64-year-old man who presented with 3 months’ history recurrent breathlessness, platypnoea leg swelling. He had diagnosed cirrhosis variceal band ligation 2018, managed for 2 episodes hepatic encephalopathy prior to refe...

We present a case of a 54-year-old patient with cirrhosis, progressive dyspnea, and platypnea. Thoracic computed tomography (CT) showed multiple pulmonary arteriovenous malformations (PAVM), confirming the diagnosis of hepatopulmonary syndrome (HPS). Besides precisely identifying the number and location of PAVM, CT also demonstrated a striking mosaic pattern of the lung parenchyma, characterize...
