title: Congenital systemic-pulmonary collateral vein unexpectedly noticed after central venous catheter insertion.
abstract: Congenital systemic-pulmonary collateral vein (i.e. levoatriocardinal vein) is an uncommon cardiac anomaly. We report a rare case of congenital systemic-pulmonary collateral vein incidentally noticed after accidental migration of a central venous catheter. Cardiac CT showed the vertical vein connected to the left upper pulmonary vein (LUPV) and another thin abnormal vessel was shown running caudally from the LUPV, connecting to the coronary sinus. Furthermore, the normal connection between the LUPV and the left atrium remained. There were two levoatriocardinal veins from the LUPV without atrial egress failure. To our knowledge, this might be the first report of such a case.
