Anomalous subaortic left brachiocephalic vein associated with tricuspid atresia: a successful bidirectional cavopulmonary connection.

Anomalous subaortic left brachiocephalic vein is an uncommon systemic venous anomaly. Here we report a case of this anomaly in a 3-month-old male infant with tricuspid atresia. The patient successfully underwent bidirectional cavopulmonary connection without cardiopulmonary bypass, although extended dissection of the bilateral brachiocephalic veins was required. The association of this venous anomaly with tricuspid atresia is extremely rare, and the presented patient is the second successful surgical case in the literature.
