Hepatopulmonary Syndrome


Risk

  • Occurs in up to 10–32% of pts with cirrhosis.

  • Dyspnea is present in up to 70% of cirrhotic pts for varying reasons (ascites, ILD, volume overload, anemia).

Perioperative Risks

  • Hypoxemia, often worsened on induction and post LT

  • Aspiration

  • Hemodynamic instability and CV collapse

  • Acute/chronic renal insufficiency

  • Myocardial infarction

Worry About

  • Full stomach and aspiration risk in presence of ascites and increased intraabdominal pressures

  • Hypoxemia (exacerbated in immediate post LT period)

  • Severe post LT hypoxemia and possible RV failure related to pulm vasoconstriction from an abrupt change in vascular mediators from the new liver

  • Hemodynamic instability, especially related to reperfusion during LT

Overview

  • Pulm complication of cirrhosis resulting in arterial hypoxemia.

  • Defined as triad of liver disease, intravascular pulm vasodilatation, and abnormal gas exchange.

  • Cirrhosis pts with hepatopulmonary syndrome have a higher mortality than those without it.

  • Liver transplant is the only definitive treatment.
