iatrogenic cyanosis in children, a pitfall of atrial septal defect repair

Today surgical repair of different types of atrial septal defect (asd) is considered as relatively a simple and safe procedure with minor to nil morbidity and mortality. when a complication occurs after asd repair, is associated with considerable morbidity and mortality, which is much higher than primary surgical procedure. we report two patients that underwent asd repair with caval inflow occlusion without cpb with late presentations of iatrogenic diversion of inferior vena cava to left atrium and subsequent complications of right to left shunting.
