Pulmonary artery size and flow disturbances after patent ductus arteriosus coil occlusion

Our experience suggests that flow disturbances in the LPA and descending aorta may occur after coil occlusion of the PDA; however, these are usually minor and resolve with time. Left pulmonary artery relative size may decrease following patent ductus arteriosus coil occlusion. Thus, serial followup echocardiography is recommended to assess long-term LPA growth.
