Treatment of an Abdominal Aortic Aneurysm Infected by Coxiella Burnetii Using a Cryopreserved Allograft

Abstract

Q fever is a worldwide zoonosis caused by an intracellular bacillus named Coxiella burnetii (CB) and is a rare cause of vascular infections. We report a case of abdominal aortic aneurysm infected by CB with bilateral paravertebral abscesses and contiguous spondylodiscitis treated by open repair using a cryopreserved allograft and long-term antibiotic therapy by oral doxycycline and oral hydroxychloroquine for a duration of 18 months. Twenty months after the operation, the patient had no infections signs and vascular complication.
