Abstract
Transcatheter occlusion with Gianturco coils has become the treatment of choice for small patent ductus arteriosus (PDA). Coil occlusion was attempted in 20 patients with ductus diameter less than 4 mm who did not require other cardiac surgery. Sixteen of 20 patients had successful implantation. The mean age was 4.2 years. Their mean weight was 14.1 ± 5.9 kg. The mean ductus diameter was 2.21 ± 0.91 mm (range 1-3.7 mm). Nine patients had complete occlusion but 7 had residual shunting immediately after the procedure. However, 4 patients had spontaneous resolution of residual shunts at 6 months after the procedure. The other 3 who had diameter of ductus greater than 3 mm still had significant residual shunt at 6 months and 1 year after the procedure. The second coil was successfully implanted in one of these 3 patients and the closure of PDA was accomplished. We concluded that the second coil should be implanted if the ductus diameter is greater than 3 mm and significant residual shunt is still demonstrated angiographically after the first coil implantation.
