Transcatheter occlusion of the patent ductus arteriosus with a single device technique: comparison between the Cook detachable coil and the Rashkind umbrella device

Transcatheter coil occlusion of the patent ductus arteriosus (PDA) has become the interventional treatment option of choice. Immediate occlusion of any residual shunting results in excellent closure rates, but frequently requires multiple coil deployment. Aims: To assess the efficacy and limitations of single Cook detachable coil PDA closure compared to a preceding series of Rashkind umbrella procedures. Methods and results: Between 1990 and 1999, transcatheter occlusion of a small (
