Hepatopulmonary syndrome (HPS), a lung complication of liver disease, causes breathing issues due to blood vessel changes. Liver transplantation can reverse HPS, suggesting it may be an indication for the procedure.

Area of Science:

  • Pulmonology
  • Hepatology
  • Cardiology

Background:

  • Hepatopulmonary syndrome (HPS) is a pulmonary complication frequently associated with liver cirrhosis.
  • Its pathogenesis remains unclear, characterized by hypoxemia from intrapulmonary shunts or vasodilatation and V/Q mismatch.
  • Key symptoms include platypnea and orthodeoxia, indicating positional dyspnea and reduced oxygen levels.

Purpose of the Study:

  • To review the understanding of hepatopulmonary syndrome (HPS).
  • To discuss diagnostic methods and current therapeutic approaches.
  • To evaluate the role of liver transplantation in managing HPS.

Main Methods:

  • Review of clinical features, diagnostic criteria, and treatment modalities for HPS.
  • Analysis of the impact of transjugular intrahepatic portosystemic shunt (TIPS) and orthotopic liver transplantation (OLTx) on HPS.

  • Exclusion of arteriovenous fistula via pulmonary angiography.

    • Main Results:

    • HPS diagnosis relies on clinical signs (platypnea, orthodeoxia), blood gas analysis, echocardiography, and perfusion scanning.
    • No definitive medical treatment exists, but TIPS shows potential for improvement.
    • Orthotopic liver transplantation (OLTx) has demonstrated reversibility of HPS in some patients.

    Conclusions:

    • HPS is a significant complication of liver disease with characteristic symptoms and diagnostic findings.
    • While current medical treatments are limited, interventions like TIPS may offer benefits.
    • Severe HPS can be reversed by OLTx, potentially making it an indication for transplantation rather than a contraindication.
