Total arch replacement with open stent-grafting for aneurysm of ductus arteriosus after surgery for patent ductus arteriosus.

A 73-year-old woman who had undergone ligation of patent ductus arteriosus (PDA) via a left thoracotomy 19 years earlier was admitted to our hospital under the diagnosis of thoracic aortic aneurysm. An enhanced computed tomography of the chest revealed a saccular aneurysm measuring a maximum diameter of 28 mm in the lesser curvature of the distal aortic arch; she was diagnosed with an aneurysm of ductus arteriosus after surgery for PDA. We performed total aortic arch replacement with open stent-grafting through median sternotomy. This approach enabled us to avoid the risk of dissecting adhesions around the aneurysm and clamping the aorta distal to the aneurysm.
