2 Liver Cirrhosis Diffuse fibrosis or scarring of the liver. Common causes: Alcohol abuse Chronic viral hepatitis (B & C) Biliary cirrhosis (primary & secondary) Metabolic: Hemochromatosis Wilson dis, alfa-1- antitrypsin Autoimmune diseases (autoimmune hepatitis) Drugs and toxins Portal hypertension and hepatic failure

3 Mechanism of Portal HTN Cirrhosis Resistance portal flow Mechanical Nodules Dynamic Nitric oxide

4

5 Portal Hypertension Hepatic fibrosis resists the inflow from the portal veins. Increases the portal venous pressure. Results in: Varices (gastric & esophageal) Ascites Splenomegaly Hepatic encephalopathy from portal-systemic shunting Hepatorenal Sy

6 Portal Hypertension - Therapy Drugs Therapy: Beta-blockers or long-acting nitrates Vasopressin, NTG, Octreotide & Somatostatin Variceal Band Ligation. Sclerotherapy TIPS DSRS Liver transplant

7 Portal Hypertension - Therapy Intervencije sa redukcijom povišenog portnog pritiska TIPS Rekanalizacija hepatic venous outflow Rekanalizacija okludirane VP i grana Embolizacija art-portnih fistula Parcijalna splenična embol. Revizija hirur-radiol. šantova Palijativne procedure Perkutana transhepatična embolizacija variksa BRTO balon retrogradna obliteracija gastričnih variksa
