Aortoiliac aneurysms infected by Campylobacter fetus

Abstract

Campylobacter fetus infection of aortoiliac aneurysms is a serious condition with a high rate of rupture. However, long-term success can be obtained with prompt surgical treatment and an appropriate antibiotic regimen. The benefits of stent grafts remain debatable.

Mycotic Aneurisma of the Abdominal Aorta Caused by Campylobacter fetus

“…7,8 There are no characteristic tomographic signs for C. fetus infection; nevertheless, the majority of the cases reported show evidence of a retroperitoneal fibrous reaction. 6 CT angiography at admission of our patient showed increased periaortic fat density, and the second demonstrated an important retroperitoneal fibrotic reaction.…”

“…3 It is associated with severe systemic diseases, such as meningitis, endocarditis, pneumonia or, in some cases, mycotic aneurysms. 6 Unlike C. jejuni, the presentation of diarrhea is uncommon. 3 Our case started with colicky abdominal pain and 3 days of diarrhea.…”

Infected Abdominal Aortic Aneurysm Caused by <i>Campylobacter Jejuni</i>

“…Although there are several reports regarding infected aneurysms caused by Campylobacter species, the majority are caused by Campylobacter fetus (C. fetus) . 2 – 5 ) C. fetus is known to spread throughout the body by the hematogenous route and to have an affinity for vascular endothelium. For such reason, it tends to infect circulatory organs.…”

<i>Campylobacter Fetus</i> Infection of the Aorta: A Case Report and Review of Literature

“…Two patients had EVAR and both died. One, a 76 year old male with an 11 cm abdominal aortic aneurysm with contained rupture underwent endovascular stent graft placement; he died of sepsis 2 weeks after the procedure (Cochennec et al, 2008). The other, a 76 year old man with an abdominal aortic aneurysm without rupture had EVAR with a dacron stent graft placed but he died 15 days postoperatively due to sepsis (Brossier et al, 2012).…”

“…Regarding C. fetus most authors report treatment ranging from as short as 7 days to as long as 52 weeks. Cochennec et al (2008) in their five cases described the use of IV amoxicillin and clavulanate or Imipenem, alone or in combination with gentamicin until the fever subsided or inflammatory markers were near normal. They followed this with long term oral antibiotics (duration not specified).…”
