TRANSCATHETER CLOSURE OF PATENT DUCTUS-ARTERIOSUS IN CHILDREN WEIGHING LESS-THAN-10KG WITH GIANTURCO COILS USING THE BALLOON OCCLUSION TECHNIQUE

We evaluated the immediate and intermediate follow-up results of trans catheter closure (TCC) of patent ductus arteriosus (PDA) using Giantur co coils in children weighing <10 kg, The results of PDA less than or equal to 2.5 mm (group I, n = 18) and >2.5 mm (group II, n = 16) were compared. coils were deployed sequentially by transarterial route usin g a temporary balloon occlusion technique. The immediate clinical succ ess rate in both groups was comparable. There was no significant diffe rence in the number of coils required per patient and in the embolizat ion rate between the two groups. Both groups had comparable occlusion rates at intermediate-term follow-up. At intermediate follow-up, one p atient 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 saf e in children weighing <10kg with gratifying intermediate-term results .
