Budd-Chiari syndrome (BCS) causes postsinusoidal portal hypertension, which leads to complications similar to those observed in cirrhosis. However, no studies have investigated whether patients with BCS develop the hyperdynamic circulatory syndrome present in patients with cirrhosis who have portal hypertension. We evaluated systemic and cardiopulmonary hemodynamics, plasma renin activity, aldosterone ...

BACKGROUND: The most frequent diagnoses for liver transplantation are virus-induced cirrhosis (VIC) and alcoholic liver disease (ALD), after an abstinence period of at least 6 months. Chronic ethanol consumption has been linked to an abnormal neuroendocrine-immune axis and to an altered surgical stress response inducing an increased infection rate. Preoperative ...

Dietary sodium restriction and diuretic treatment have been shown to be effective in the treatment of ascites in the majority of cirrhotic patients. However, approximately 5 to 10% of patients develop refractory ascites, which is defined as ascites that does not respond to intensive diuretic therapy (diuretic-resistant) or ascites that ...

Ascites is a significant complication of cirrhosis that occurs in approximately 50% of patients. The mortality rate is high in patients with cirrhosis and ascites. Conventional interventions rest with dietary sodium restriction, diuretic use, large-volume paracentesis, peritoneovenous shunts and transjugular intrahepatic portosystemic shunts. The mainstay of therapy, however, is the ...
