title: Transcatheter occlusion of the patent ductus arteriosus: use of the retrievable coil device.
abstract: The Cook Retrievable Embolization Coil has been designed to improve delivery and positioning during coil embolization of the patent ductus arteriosus (PDA). We report our experience with the use of this new technique. Twenty-eight patients underwent coil embolization of a PDA using the retrievable system. The median patient age was 4.5 years (range, 2 months to 33 years), median weight 17.2 kg (range, 3.1-100 kg). The mean minimum diameter was 1.1 mm (range, 0.3-3.8 mm). One or two Cook Retrievable Embolization Coils were implanted in each PDA. Successful delivery was achieved in 27 cases. There was no shunt by angiography in 19 of the patients (70%). Color echocardiography documented no shunt in 13 of 17 patients (77%). The retrievable coil system represents a successful method of PDA occlusion with good control of coil positioning and delivery.
