Objectives The increase in endovascular aortic aneurysm repair has led to increasing incidence of aortic endograft infections. Additionally, more atypical organisms are being identified as pathogens. We report on a rare aortic endograft infection to further characterize and understand these infections. Methods We report a Clostridium difficile culture–positive aortic endograft infection in an 82-year-old male 3 years after endovascular abdominal aortic aneurysm repair. Results The patient underwent successful open, complete explant of his endograft and in-situ repair using a rifampin-soaked Dacron graft. He continues to do well. Conclusions Aortic endograft infections are a complex problem further complicated by rare and virulent infections. Unless the patient is at prohibitive risk, the management of infected aortic endografts is surgical graft explant and in-situ or extra-anatomic reconstruction due to the exceedingly high mortality rate with non-operative management.

Abstract Background HACEK (Haemophilus spp., Aggregatibacter spp., Cardiobacterium spp., Eikenella corrodens, and Kingella spp.) group organisms are responsible for 0.8% to 6% of all infective endocarditis cases, with Cardiobacterium spp. being the third most commonly implicated HACEK microorganism. Within this genus is Cardiobacterium valvarum (C. valvarum), a novel organism described in 2004. To date, only 15 cases of C. valvarum infection have been reported in the English-language literature, and have primarily been cases of infective endocarditis in patients with valvular disease. C. valvarum has not been reported to cause infections spreading to the surrounding bone. Case presentation We present a case of a 57-year-old man with a history of aortic dissection followed by aortic endograft replacement who presented with back pain. He was found to have radiographic evidence of an infected aortic endograft, along with vertebral osteomyelitis, discitis, and epidural phlegmon. Blood cultures identified C. valvarum as the causative organism. The patient was treated with ceftriaxone and surgical intervention was deferred due to the patient’s complex anatomy. His course was complicated by septic cerebral emboli resulting in cerebrovascular accident. Conclusions This case report highlights C. valvarum, a rare and emerging HACEK group microorganism that warrants consideration in high-risk patients with evidence of subacute infection and disseminated disease. While C. valvarum classically presents as infective endocarditis, extra-cardiac manifestations have also been described. As demonstrated in this case, endograft involvement and osteomyelitis may occur in rare circumstances.

Aortoenteric fistula after endovascular aortic repair for an abdominal aortic aneurysm is a rare but severe complication. Particularly, a case of inflammatory abdominal aortic aneurysm is extremely rare and there are only 3 reported cases. A 70-year-old man underwent endovascular aortic repair for impending rupture of an inflammatory abdominal aortic aneurysm and was medicated steroids for approximately 2 years. Four years after endovascular aortic repair, he developed endograft infection with an aortoduodenal fistula and a left psoas abscess. He underwent total endograft excision, debridement, in situ reconstruction of the aorta using prosthetic grafts with omental coverage, and digestive tract reconstruction to prevent leakage. Pseudomonas aeruginosa was detected in the infected aortic sac. The patient has not experienced recurrence of infection in the 35 months since his operation.
