Commonly associated with hepatic cirrhosis and can also occur with non-cirrhotic liver disease Results in  o Ascites o Esophageal varices ▪ Top 2 are main symptoms o Caput medusae ▪ Sign of severe portal hypertension Ascites Seen with cirrhosis, cancer, heart failure Contributing factors: o Portal hypertension resulting in increased capillary pressure and obstruction of venous blood flow o Vasodilatation of splanchnic circulation (blood flow to the major abdominal organs) o Changes in the ability to metabolize aldosterone, increasing fluid retention o Decreased synthesis of albumin, decreasing serum osmotic pressure o Movement of albumin into the peritoneal cavity Ascites: Assessment Daily abdominal girth and weight Striae, distended veins, or umbilical hernia Potential fluid and

underlie its development in acute and chronic liver disease o Hepatic insufficiency: the inability of the liver to detoxify toxic by-products of metabolism (e.g., salts, urea, ammonia) o Portosystemic shunting: collateral vessels develop allowing elements of the portal blood (laden with potentially toxic substances usually extracted by the liver) to enter the systemic circulation Early signs: mental changes and motor disturbances o Can be reversed when caught early Later stages: life threatening Hepatic Encephalopathy: Assessment Stages of Hepatic Encephalopathy Hepatic Encephalopathy Asterixis o Involuntary flapping of hands o Seen in stage 2 encephalopathy Apraxia o Inability to write/draw figures Hepatic Encephalopathy: Treatment Eliminate precipitating cause Lactulose to reduce

complications and infections Portal Systemic Shunts Treats portal pressure Transjugular Intrahepatic Portosystemic Shunt (TIPS) TIPS is a shunt (tube) placed between the portal vein which carries
