Left innominate vein-pulmonary artery shunt with Glenn anastomosis in a Fontan candidate with central pulmonary artery stenosis.

摘要

Heart failure developed 9 years after Fontan takedown with systemic-pulmonary artery shunt in a 12-year-old girl with pulmonary atresia, intact ventricular septum, and obstruction in the proximal pulmonary artery. Surgical scar after multiple operations complicated direct repair of the pulmonary artery, and thus she was not eligible for definitive palliation. Left innominate vein-to-left pulmonary artery shunt using an expanded polytetrafluoroethylene conduit in association with Glenn anastomosis functionally established an unobstructive superior cavopulmonary connection without direct repair of the central pulmonary artery, later facilitating one and a half ventricle repair. Use of an extraanatomical shunt may functionally relieve central pulmonary artery obstruction in candidates for Fontan-like circulation.
