Suprarenal aortic aneurysm closure with an atrial septal defect Amplatzer device.

Conventional repair of pararenal aortic aneurysms has been a technically challenging operation, with a significant morbidity rate of 28-35%. Endovascular stent grafting requires satisfactory landing zones for stent graft anchoring. Therefore, pararenal abdominal aortic aneurysms are usually contraindicated for this procedure because of difficulties associated with proximal graft fixation.
