Glenn anastomosis
Pronunciation: GLEN an-as-to-MO-sis
Connection between superior vena cava and pulmonary artery as part of single-ventricle surgical palliation.
Full Definition
A surgical connection that directs venous return from the upper body directly to the pulmonary circulation, bypassing the heart. The bidirectional Glenn connects the superior vena cava to the right pulmonary artery while maintaining flow to both lungs. This procedure is typically the second stage in single-ventricle palliation (after Norwood) and precedes the Fontan completion. The Glenn reduces volume load on the single ventricle while maintaining adequate pulmonary blood flow and oxygenation.
Usage
Usage note: Named after William Glenn; capitalize as proper noun. Specify bidirectional vs. classic Glenn.
