Direct visualization of postoperative aortobronchial fistula on computed tomography

Figure 5 Aortobronchial fistula in a 73-year-old man with fever and a history of thoracic endovascular aortic repair 1 year earlier for infected aneurysm. One year after the surgery, peri-graft air was first noted when he was diagnosed with a stent graft infection. He was treated with antibiotics, and the infection was brought under control, but a year later the stent graft infection recurred and he died of sepsis. A: Initial/onset computed tomography (CT) images show air shadow in the intra-aortic peri-graft space (arrow), but without direct connection between bronchioles and perigraft air; B: Latest CT images show increased peri-graft air (arrow) and dilated peripheral bronchi (left B1 + 2) communicating with air (arrow). Lt: Left; MinIP: Minimum intensity projection.
