Abstract

Purpose of Review

Hepatopulmonary syndrome (HPS) is a syndrome of hypoxemia in patients with advanced liver disease, which results in significant mortality in the absence of liver transplantation. Management of HPS is complex both prior to and following liver transplantation as illustrated by a case presentation. This review considers the pathophysiology, diagnosis, assessment of severity, and treatment of HPS with a particular emphasis on perioperative management.

Recent Findings

Screening for HPS should be performed in all liver transplant candidates with room air saturation less than 97%. Diagnosis of HPS has been standardized with the use of agitated saline-enhanced echocardiography. Treatment modalities for profound hypoxemia include patient positioning, transtracheal oxygenation, nitric oxide therapy, intravenous methylene blue, and extracorporeal membrane oxygenation. Fortunately, patients with HPS who undergo successful liver transplantation will often have complete resolution of the symptoms related to HPS, although this may require weeks to months.

Summary

Despite technical challenges, liver transplantation for HPS can be safely performed provided patients are identified and appropriately managed. Physicians caring for these patients should be prepared to use all available interventions including extracorporeal oxygenation to allow time for the HPS to resolve and oxygenation to improve. Further investigation is needed to identify effective medical treatments to mitigate HPS-related hypoxemia.
