We report cases of recanalization of ilio-femoral veins (IFV) using stents in infants. Case1 is a 4-month-old girl presented with pulmonary venous obstruction (PVO) complicating intracardiac repair of total anomalous pulmonary venous connection (TAPVC) Ia. After intracardiac repair of TAPVC at 14 days, she developed PVO after surgery. Despite atrial septal defect (ASD) creation, at 2 month .she developed PVO again at 3 months. Stents were implanted in the bilateral PVs. One month later, we found an occluded right iliac vein. We implanted 2 stents in the right IFV. Because of restenosis, we implanted a third stent at 7 months of age. Case2 is a 19-month-old girl presented with double outlet right ventricle, ventricular septal defect (DORV), partial anomalous pulmonary venous connection (PAPVC), and patent ductus arteriosus (PDA) complicated by left congenital cystic adenomatoid malformation (CCAM) and pulmonary sequestration. We performed a lobectomy, followed by PDA ligation and pulmonary artery banding at 1 month; because hypoxia progressed at 17 months,an atrial septal defect was created by the transcatheter method, followed by stent implantation in the atrial septal defect 2 months later. Severe stenosis was detected in the right IFV. We implanted 2 stents. Follow-up echocardiography confirmed good blood flow. Transcatheter recanalization for stenosis of the IFV using stents is feasible in infants. Further evaluation is needed.
