Direct visualization of postoperative aortobronchial fistula on computed tomography

Figure 2 Aortobronchial fistula in an asymptomatic 73-year-old woman with a history of ascending aorta and aortic arch replacement + thoracic endovascular aortic repair 5 years earlier for dissection. A: Initial computed tomography (CT) images show air shadow in the intra-aortic peri-graft space (arrow); B: Latest CT, 5 months follow-up images show dilated peripheral bronchus (right B3) communicating with peri-graft air(arrow); C: Latest CT, 5-month follow-up images show residual peri-graft air. There were no severe complications during the 5-month observation period. AAo: Ascending aorta; Rt: Right; MinIP: Minimum intensity projection.
