Sueblinvong V The authors reported the results in transcatheter coil occlusion of patent ductus arteriosus
(PDA) Jess than 4 mm, based on a policy in selection of the appropriate type and number of coils for
size of PDA. The authors used one 0.035 inch detachable coil, 5 mm in diameter, in PDA less than
or equal to 2 mm, and two 0.035 inch detachable coils or one controlled release 0.052 inch Gianturco
coil in PDA larger than 2 mm. The present study included 32 pediatric patients. There were 31 cases of
successful coil implantation and 1 case failed. Of the 31 successful cases, PDA size varied from 1.4
to 4.0 mm (mean of 2.7
เธ‘
0.9 mm). Ten patients had a PDA size of Jess than or equal to 2 mm (group
A), while the other 21 patients had a PDA size of larger than 2 mm (group B). In group A, 9 cases
had single-detachable-coil occlusion and one case had double-detachable-coil occlusion. In group B,
double-detachable-coil occlusion was performed in 17 cases and controlled release 0.052 inch coil in
4 cases. There were no cases of coil migration or other serious complications. The immediate complete
occlusion rate was 58 per cent ( 18 of 31 cases), which rose to 97 per cent (30 of 31 cases) at the mean
follow-up of 2.6
เธ‘
2.5 months (range from 1 day to 9 months).
Transcatheter coil occlusion is an alternative to surgical closure of small PDA (Jess than 4
mm). Selection of type and number of coils appropriate to the size of PDA will allow safe and excellent
results.
