Portopulmonary hypertension (PoPH) and hepatopulmonary syndrome (HPS) present two vascular complications of portal hypertension, which make opposite extremes occur against the same pathophysiological background. In PoPH, vasoconstriction predominates...

Hepatopulmonary syndrome (HPS) is a lethal complication of cirrhosis characterized by hypoxia and overt intrapulmonary shunting. In this study, we investigated the effect of caffeine in rats with common bile duct ligation (CBDL)-induced liver cirrhos...

Background: Hepatopulmonary syndrome (HPS), defined by the presence of pulmonary vascular dilatations that cause right-to-left transpulmonary shunting of venous blood with a consequential increase in the alveolar–arterial oxygen gradient, is a...

Background: Hepatopulmonary syndrome (HPS) is a pulmonary vasculature complication in the setting of liver disease that is characterized by pathological vasodilation resulting in arterial oxygenation defects. We investigated the role of extracellular...

The common cause of porto-pulmonary hypertension and hepato-pulmonary syndrome is portal hypertension. Porto-pulmonary hypertension (PPHTN) is a form of pulmonary arterial hypertension, and hepato-pulmonary syndrome (HPS) occurs as a consequence of h...

This paper presents a case of a young patient with cyanosis and digital clubbing, until then an active, sporty person. He sought medical assistance due to the growing dyspnoea and the drop of effort tolerance. Initially the diagnostic process focused...

Background: Extracorporeal membrane oxygenation (ECMO) is an accommodation of the cardiopulmonary bypass technique that can support gas exchange and hemodynamic stability. It is used as a salvage maneuver in patients with life-threatening respiratory...

Background: The prevalence of portopulmonary hypertension (PoPH) is relatively low; however, its presence significantly worsens patients’ prognosis. When diagnosed, PoPH can be effectively treated, and specific therapies can lead to a substanti...

Background: Congenital portosystemic shunts (CPSS) are rare vascular anomalies resulting in communications between the portal venous system and the systemic venous circulation, affecting an estimated 30,000 to 50,000 live births. CPSS can present at...

Biliary atresia (BA) is an obliterative disease of the bile ducts affecting between 1 in 10,000–20,000 infants with a predominance in Asian countries. It is clinically heterogeneous with a number of distinct variants (e.g., isolated, Biliary At...

Cystic fibrosis (CF) is a multifaceted disorder predominantly investigated for its pulmonary manifestations, yet patients with CF also exhibit a spectrum of extrapulmonary manifestations, notably those involving the hepatobiliary system. The latter c...

Portopulmonary hypertension (PoPH) and hepatopulmonary syndrome are severe pulmonary complications associated with liver cirrhosis (LC) and portal hypertension. Three key pathways, involving endothelin, nitric oxide, and prostacyclin, have been ident...
