Sumario:INTRODUCTION: Coxiella burnetii, the causative agent of Q fever, may cause endocarditis and vascular infections that result in severe morbidity and mortality. We report a case of a C. burnetii-infected abdominal aorta and its management in a patient with a previous endovascular aortic aneurysm repair. CASE PRESENTATION: A 62-year-old Caucasian man was admitted to our hospital three months after endovascular aortic aneurysm repair with a bifurcated stent graft. He had increasing abdominal complaints and general malaise. A computed tomography scan of his abdomen revealed several para-aneurysmal abscesses. Surgery was performed via midline laparotomy. The entire abdominal wall of his aneurysmal sac, including the abscesses, was removed. The vascular endoprosthesis showed no macroscopic signs of infection. The decision was made to leave the endograft in place because of the severe cardiopulmonary comorbidities, thereby avoiding suprarenal clamping and explantation of this device with venous reconstruction. The proximal and distal parts of the endograft were secured to the aortic wall and common iliac artery walls, respectively, to avoid future migration. Polymerase chain reaction for C. burnetii was positive in all specimens of aortic tissue. Specific antibiotic therapy was initiated. Our patient was discharged in good clinical condition after six days. CONCLUSIONS: In our patient, the infection was limited to the abdominal aneurysm wall, which was removed, leaving the endograft in place. Vascular surgeons should be familiar with this bailout procedure in high-risk patients.
