Transcatheter occlusion of patent ductus arteriosus using a 0.052-inch coil--immediate results.
Coil occlusion of a patent ductus arteriosus (PDA) was attempted with a 0.052-inch Gianturco coil. The patients' ages and body weights at occlusion ranged from 5.8 to 19.7 (12.3+/-5.0, mean+/-SD) years and 18.9-99.1 (44.8+/-23.7) kg, respectively. Three types of 0.052-inch Gianturco coils with loop diameters (mm) and coil lengths (cm) of 6x8 (diameter x length), 8x8, or 8x10 were used. The delivery system was prepared as reported by Hays et al with slight modification. The minimal diameter and the Qp/Qs of the PDA ranged from 2.3 to 4.7 (3.4+/-0.7) mm, and 1.1-1.8 (1.5+/-0.3), respectively. There were 7 cases with type A PDA and 3 with type B, and coils were successfully deployed in all. Complete occlusion in the catheter laboratory was achieved in 4 cases. A minor leak disappeared within 24 h in 3 cases and at 3 months follow-up in 1 case. A tiny leak without a heart murmur persisted in 2 cases at 3 months' follow-up. No procedure-related complications occurred. This technique has significant advantages over previously reported techniques using a 0.038-inch coil for type B, or A PDA with a minimal diameter of 3-4 mm or more.
