Successful Percutaneous Revascularization for Femoral Artery Occlusion After Catheter Intervention: Serial Case Report

Femoral artery (FA) occlusion is a prevalent adverse event after catheter interventions, particularly in neonates and infants. Several treatments are available for FA occlusion, but the optimal approach remains unknown. Herein, we report three cases of infants with FA occlusion after catheter interventions, which were successfully treated by transcatheter revascularization. Case 1 is a 1-month-old boy with pulmonary valve stenosis who was treated with percutaneous transluminal pulmonary valvuloplasty. Case 2 is a 5-month-old boy with truncus arteriosus who underwent percutaneous transluminal angioplasty for pulmonary artery stenosis after intracardiac repair. Case 3 is a 3-month-old boy with pulmonary atresia and an intact ventricular septum treated with transluminal angioplasty for bilateral pulmonary artery banding site stenosis. All three cases were detected for FA occlusion within 1 day after the intervention and successfully recanalized by transcatheter angioplasty within four days after the intervention. Transcatheter revascularization can be used as potential treatment option for FA occlusion after the catheter procedure.
