Abstract
Hepatopulmonary syndrome (HPS) poses a significant challenge in liver transplant patients, affecting between 10% and 30% of candidates. Historically, HPS was considered a contraindication for liver transplantation due to its association with high mortality rates. However, recent studies have shown improvements in pulmonary function post-transplant, leading to the inclusion of these patients as candidates. Despite this progress, approximately one-fifth of liver transplant recipients develop severe postoperative hypoxia, further complicating their clinical course and contributing to increased mortality. The management of post-transplant HPS involves various strategies, including extracorporeal membrane oxygenation (ECMO), although its use remains infrequently reported. Theoretical models suggest that oxygenation typically improves within 10 days post-transplant, while resolution of HPS may take 6-12 months, making ECMO an attractive possibility as a bridge to recovery in this population. We present a case were ECMO was used in this context.
期刊介绍:
The International Journal of Artificial Organs (IJAO) publishes peer-reviewed research and clinical, experimental and theoretical, contributions to the field of artificial, bioartificial and tissue-engineered organs. The mission of the IJAO is to foster the development and optimization of artificial, bioartificial and tissue-engineered organs, for implantation or use in procedures, to treat functional deficits of all human tissues and organs.
