Direct visualization of postoperative aortobronchial fistula on computed tomography

Figure 7 Aortobronchial fistula in an 83-year-old asymptomatic man and a history of descending aorta replacement 23 years earlier for an aneurysm. A: Initial computed tomography (CT) images show air shadow in the intra-aortic peri-graft space (arrow); B: Latest CT, 7-year follow-up images show residual peri-graft air. A dilated peripheral bronchus is near the graft, but without direct connection with peri-graft air. No severe complications occurred during the 7-year observation period. DAo: Descending aorta.
