Core Tip

Core Tip: This retrospective study included six patients with aortobronchial fistula based on computed tomography (CT) findings of peri-graft air, with aortobronchial fistula being detected a mean of 14 years after thoracic aortic surgery. Asymptomatic aortobronchial fistula can be confirmed on chest CT as direct communication between dilated peripheral bronchi and peri-graft air. CT is useful for the diagnosis of aortobronchial fistula and its complications.
