Device Closure of Patent Ductus Arteriosus PDA

Device closure of the patent ductus arteriosus can be approached both from the arterial side and the venous side. Several variations of the method exist in literature. One method which was followed by us is described here. Initially an angiogram (descending aortogram) is taken to confirm the size of the PDA to choose the size of the device. This angiogram shows pigtail catheter in the descending aorta and the contrast passing from the descending aorta to pulmonary artery through the PDA. The PDA is superimposed on the tracheal air column in this view.
