When the bi-directional Glenn is an unfavourable option: primary extracardiac inferior cavopulmonary connection as an alternative palliation

Abstract

AbstractThe superior cavopulmonary anastomosis – bi-directional Glenn – is the standard palliation for single ventricle physiology. When upper body systemic venous anatomic concerns such as superior caval vein stenosis, hypoplasia, or inadequate collateral tributaries are present, a Glenn may be precluded or have a high risk of poor outcome. A primary inferior cavopulmonary connection with an extracardiac conduit is an alternative palliation that provides a generous pathway for pulmonary blood flow, with the additional benefit of including hepatic venous return. We report a case of primary extracardiac inferior cavopulmonary connection in a patient unsuitable for Glenn, with successful post-operative outcome and early follow-up.
