Abstract

A multicenter clinical trial of DuctOcclud, a new detachable coil for transcatheter occlusion of patent ductus arteriosus (PDA), was conducted. DuctOcclud was used in 35 patients (12 male and 23 female)for transcatheter occlusion of PDA between January, 1996, and April, 1997. The age of the patients ranged from 0.5 to 27.2 years (median 7.6 years) and weight from 6.3 to 70.0 kg (median 23.0 kg). The smallest diameter of PDA was 2.0±0.7 mm (range 1.0-3.3 mm). Pulmonary-systemic flow ratio (Qp/Qs) was 1.3 ± 0.3 (range 1.0-2.2). The coils were successfully implanted in 32 (91%) patients. Of 31 patients who were followed 6 months after the procedure, 26 (84%) had no residual shunt and 5 (16%) had trivial residual shunt. One patient had infective endocarditis 1 month after the procedure but recovered completely. There were no incidences of coil embolization, hemolysis, late coil migration, or pulmonary artery stenosis. We conclude that DuctOcclud is a safe and effective device of transcatheter occlusion of PDA.
