Repeat use of occluding spring coils to close residual patent ductus arteriosus.

Recent studies have shown that small- and moderate-size patent ductus arteriosus (PDA) may be closed with occluding spring coils. As with other percutaneous devices, a low incidence of residual PDAs has been observed in medium-term follow-up. This report describes experience with closing residual PDA by repeat use of occluding spring coils.
