Transcatheter closure of patent ductus arteriosus in children weighing < 10 kg with Gianturco coils using the balloon occlusion technique.

We evaluated the immediate and intermediate follow-up results of transcatheter closure (TCC) of patent ductus arteriosus (PDA) using Gianturco coils in children weighing < 10 kg. The results of PDA < or = 2.5 mm (group I, n = 18) and > 2.5 mm (group II, n = 16) were compared. Coils were deployed sequentially by transarterial route using a temporary balloon occlusion technique. The immediate clinical success rate in both groups was comparable. There was no significant difference in the number of coils required per patient and in the embolization rate between the two groups. Both groups had comparable occlusion rates at intermediate-term follow-up. At intermediate follow-up, one patient had developed left pulmonary artery stenosis while obstruction of the descending aorta was not seen in any; in 4 children the PDA had recanalized. Spontaneous reocclusion was observed in 3 of the latter at the last follow-up. We conclude that TCC of PDA is feasible and safe in children weighing < 10 kg with gratifying intermediate-term results.
