Use of computed tomography-guided biopsy to detect Peptostreptococcus micros-induced mycotic abdominal aortic aneurysm after endovascular repair

Mycotic aortic aneurysm (MAA) is rare but lethal. Detection of the causative bacteria is important for successful treatment. In some cases, however, no micro-organisms are detected by repeated blood cultures. Open surgery is the standard procedure for MAA, but endovascular intervention is also performed. An aneurysm specimen cannot be taken for culture when using an endovascular approach, decreasing the opportunity to detect the causative organism. We performed successful endovascular repair in a rare case of a Peptostreptococcus micros-induced MAA as detected by postoperative computed tomography-guided biopsy. This case may help to establish appropriate medical treatment for MAAs. Keywords: Mycotic aneurysm, Endovascular, Stent graft, Peptostreptococcus micros, Computed tomography-guided biopsy
