Migration of an Atrial Septal Occluder Device With Formation of Abdominal Aortic Dissection.

Atrial septal defects can be closed surgically or percutaneously. However, percutaneous closure of atrial septal defects carries some risks. Embolization of the atrial septal occluder is the major adverse event. Embolization of the device into the main pulmonary artery, left atrium, right ventricle, aortic arch, descending aorta, abdominal aorta, iliac bifurcation, and iliac arteries can be seen. We report the case of a 19-year-old man with migration of an Amplatzer (St Jude Medical, St Paul, MN) atrial septal occluder into the iliac bifurcation with the development of abdominal aortic dissection 1 month after successful percutaneous closure.
