Management of patients with single-ventricle physiology is significantly affected by anomalies of pulmonary venous return at all stages, whether primary palliation, bidirectional Glenn shunt, or completion of Fontan circulation. We treated 25 patients with pulmonary venous anomalies and single ventricle by staged palliation, from June 1996 to May 2005. Visceral heterotaxy with atrial isomerism was present in 19 of them. Primary palliation with a systemic-to-pulmonary artery shunt was undertaken in 15 patients. There were 5 early deaths, of which 4 were due to obstruction of pulmonary venous return. A bidirectional Glenn shunt was constructed in 17 patients including 10 who had it as a primary palliative procedure. There were 7 early deaths after the bidirectional Glenn procedure; only one was due to pulmonary venous obstruction. Five patients attained completion of the Fontan procedure. There was one early death after the Fontan operation. Anomalous pulmonary venous return can significantly complicate the management of patients with single ventricle, with an impact on survival in early infancy. Palliation with the aim of instituting extracardiac conduit Fontan circulation allows greater latitude and more streamlined management.
