A Case of Pulmonary Arteriovenous Shunt Diagnosed by Microbubble Test via a Swan-Ganz Catheter.

When encountering severe hypoxemia that does not respond to oxygen supplementation, it is essential to consider underlying right-to-left shunting. Among various diagnostic approaches, the microbubble test via transthoracic echocardiography (TTE) is a simple, noninvasive method for detecting pulmonary arteriovenous shunts, particularly in hepatopulmonary syndrome (HPS). Although microbubbles are usually administered peripherally, using a Swan-Ganz (SG) catheter to inject microbubbles directly into the pulmonary artery may provide even more definitive diagnostic information.

Hepatopulmonary syndrome (HPS) is a serious pulmonary vascular complication that causes arterial hypoxemia in the setting of liver disease. HPS has a progressive course and is associated with a two-fold increased risk of mortality relative to cirrhotic patients without HPS. It primarily affects patients with portal hypertension.

Article Synopsis
- Liver transplantation is the main treatment for cirrhosis patients with hepatopulmonary syndrome (HPS), but its impact on survival rates is debated.
- A study analyzed 181 liver transplant recipients, finding that 57.5% had HPS, with similar overall survival between HPS and non-HPS groups (around 69.8 vs 63.4 months).
- Results showed that HPS patients experienced more post-surgery complications like delayed extubation and chest catheter insertion, but their overall survival was not negatively affected by HPS severity.
Echocardiographic Screening of Liver Transplant Candidates-Prevalence of Features of Portopulmonary Hypertension.

: The prevalence of portopulmonary hypertension (PoPH) is relatively low; however, its presence significantly worsens patients' prognosis. When diagnosed, PoPH can be effectively treated, and specific therapies can lead to a substantial reduction in pulmonary circulation pressure, facilitating the safe performance of liver transplantation. Echocardiography is recommended as a first-line method for the non-invasive diagnosis of pulmonary hypertension and serves as a valuable screening tool for patients being evaluated for liver transplantation (LT).

Background: Hepatopulmonary syndrome (HPS) is a complication in biliary atresia (BA) children following hepatoportoenterostomy. Liver transplantation (LT) was the definitive treatment of HPS. However, little was known about the risk factors between HPS and mortalities.
