Percutaneous Transarterial Coil Occlusion of Large Patent Ductus Arteriosus

Background and purpose: We present long-term results of percutaneous transarterial coil occlusion in 13 patients with large patent ductus arteriosus (PDA), measuring 3.5mm to 5mm. Methods: From July 1997 to June 2003, a total of 13 consecutive pediatric patients underwent occlusion of large PDA with Gianturco coils via the femoral artery. Chest examination, plain chest films, and echocardiography with color Doppler were performed on all patients within 24 hours, and at 1, 2, 3, 6, 12, and 24 months after coil occlusion. Results: Eleven patients had type A PDA and two had type C PDA. Six patients (46%) underwent single coil occlusion and seven (54%) underwent multiple coil occlusion. The median ratio of pulmonary to systemic blood flow was 3.0 (range 2.3 to 5.6; mean ± SD, 3.3±0.9) before the procedure, and 1.0 (range 1.0 to 1.2; mean ± SD, 1.1±0.1) after the procedure (P=0.001). Nine patients (69%) had immediate closure of the ductus at 15 minutes after the procedure. Closure rates within 24 hours and at 1, 2, 3, 6, 12, and 24 months after the procedure were 77%, 92%, 100%, 100%, 100%, 100%, and 100%, respectively. There were no complications during long-term follow-up. Conclusions: Percutaneous transarterial coil occlusion for large PDA can he safely achieved with simple standard Gianturco coils.
