OBJECTIVE: We sought to evaluate the role of percutaneous techniques in the treatment of ductal origin of a distal pulmonary artery (PA) in low-weight infants. BACKGROUND: Various surgical approaches have been proposed, however, they are highly challenging and risky in neonates. METHODS: We treated 5 infants weighing <3 kg with ductal origin of the PA associated with other congenital heart disease. Procedures were performed under general anesthesia and orotracheal intubation. RESULTS: A total of 7 coronary stents were used. Median procedure and fluoroscopy times were 100 and 8 minutes, respectively. Oxygen saturation increased significantly in all cases (p = 0.026). Both procedural and postprocedural courses were uneventful and the patients were discharged 7-10 days post procedure. During a follow up of 4-12 months, the results remained stable. Two subjects underwent complete corrective surgery 6 months after stent implantation at a weight of 7-9 kg. Ductus arteriosus with the stent inside were completely removed by surgeons who did not report any difficulty. Three subjects await surgery. CONCLUSION: Percutaneous management of the ductal origin of the pulmonary artery is a safe and efficacious palliative approach.
