Direct visualization of postoperative aortobronchial fistula on computed tomography

Figure 1 Pseudo-aortobronchial fistula in a 75-year-old man with dyspnea, a history of aortic arch replacement 2 weeks earlier for an aneurysm, and positive pressure ventilation performed for acute respiratory distress syndrome. A: Two weeks after the operation, he underwent computed tomography (CT) because of dyspnea, and peri-graft air was noted (not seen immediately after the operation); B: The air disappeared on a CT scan performed 2 days later. There was no recurrence of air around the graft on imaging performed over a 6-year period, and no signs of graft infection.
