TRANSCATHETER CLOSURE OF PATENT DUCTUS ARTERIOSUS

Objective To explore the efficacy of transcatheter closure of patent ductus arteriosus (PDA) with detachable coil and Amplatzer duct occluder (ADO). Methods Transcatheter colsure of PDA was performed in 160 cases, aged 4.56±2.67 years, of whom 3 had residual shunt after surgical ligation, 2 had pulmomary stenosis (PS), 1 had coarctation of aorta (COA), 1 had right aortic arch, and 2 had atrial septal defect (ASD). Results Detachable coils (Duct Occlude pfm or Cook Inc) were successfully used in 51 patients with a smallest PDA diameter of 1.86±0.78mm. Amplatzer duct occluders were also successfully performed in other 109 with a moderate to large PDA diameter of 3.89±1.32mm, of whom 3 with PS or COA were performed balloon dilation firstly, and 2 with ASD were performed PDA occlusion firstly; 1 month to 4.8years follow-up coil or Amplatzer device closure of PDA showed that neither residual shunt nor any complication. Conclusion It is suggested that the detachable coil and Amplatzer duct occluder are simple and safe for the catheter closure from small to large sized PDA.
