Salmonella sepsis in a patient after infection of the aorto-biiliac stent graft implanted due to a ruptured aneurysm of the right common iliac artery – case report and literature review

Stent grafts are the most popular method of treating aneurysms.The incidence of vascular graft infection is 0.5% to 5%.In turn, the incidence of infection after percutaneous insertion of intravascular stent grafts is much lower and reaches approximately 1%, or less.The infection may be local, develop into acute sepsis, or develop into a chronic infection with septic flares.Stent graft infection in peripheral arteries is rare and dangerous.A foreign body, such as a stent graft, usually does not cause a reaction in body.However, cases of colonization with bacteria resulting in local or generalized infection have been described.Two types of body reactions to graft can be distinguished: an acute inflammatory response leading to the formation of an abscess, and a chronic inflammatory process with fibrosis.The case is presented of a patient with sepsis lasting several weeks, the result of infection of the aorto-biiliac stent graft.A review of the literature on the subject is also presented.
