Ascending aorta graft pseudoaneurysm and aortobronchial fistula caused by a fractured sternal wire: a case report.

Sternal wires can damage the adjacent vascular grafts and lead to fatal complications such as pseudoaneurysm formation. Thus, preventive measures such as using sternal bands and placing a covering layer between the sternal wires and aortic grafts are recommended in patients with dilated or replaced ascending aorta.
