Early and severe aortic endograft infection after percutaneous coil embolization of type 2 endoleak: A case report.

Endovascular aneurysm repair for abdominal aortic aneurysm is superior to open surgery regarding perioperative morbidity and mortality. Complications such as endoleaks represent a significant source of secondary intervention. Vascular graft infection is another serious complication found in 0.2 to 1 % of series. We hereby describe a case of a rapidly progressive aortic infection by Cutibacterium acnes following a percutaneous embolization procedure for a type II endoleak. A 75-year-old man presented with a fever along with lower back and buttock pain five days after embolization via direct percutaneous puncture for a type II endoleak. White blood cell scintigraphy and blood culture suggested the presence of aortitis, but the patient experienced notable spontaneous improvement in both clinical symptoms and biological markers. The patient underwent CT-angiography which revealed aneurysm rupture requiring urgent open surgery and initiation of antimicrobial therapy. Similarly to blood cultures, per-operative aortic wall tissue samples also revealed presence of Cutibacterium acnes. Aortic endograft infection after embolization is an uncommon complication. The diagnosis is based on a combination of imaging, blood, and nuclear tests. Repeated CT-angiography may be helpful when infection occurs quickly after embolization. Staphylococcus and Streptococci are common pathogens implicated in these infections. This is a case of an early and severe aortic endograft infection after percutaneous coil embolization of type 2 endoleak. Rupture occurred in less two weeks despite a slow-growing organism infection. The treatment includes endograft removal and antibacterial therapy. Caution is warranted when suspecting aortic endoprosthesis infection, necessitating close follow-up.
