Arteriovenous fistula creation for hypoxia after single ventricle palliation: A single‐institution experience and literature review

摘要

Hypoxia is a common and sometimes severe morbidity of single ventricle congenital heart disease (CHD). Creation of an arteriovenous fistula (AVF) is occasionally performed for patients after superior or total cavopulmonary connection (SCPC or TCPC) in an attempt to improve oxygen saturations. Despite previous reports, AVF creation is a rare palliation with inadequately defined benefits and risks. We sought to determine changes in peripheral oxygen saturation (SpO2) and risk of adverse event after AVF creation in children with single ventricle CHD at our institution.
