Endovascular aortic graft infection resulting in retroperitoneal abscess: report of a case.

Endovascular prostethic grafts may be related to several complication including endoleak, device migration, restenosis, thrombosis, rupture and infection. Infection is, to date, arare complication of endovascular procedures, with an incidence inferior to 0.5% but potentially catastrophic. When an endograft in the aortoliac position is involved it may result, as in open surgery implanted in a retroperitoneal abscess and aortoenteric fistulation potentially evolving to sepsis, gastrointestinal bleeding, septic or hemorragic shock. The low rate of occurrence and awareness with the relatively aspecific clinical presentation and progressive evolution seem to cause a considerably delay in diagnosis and a poor outcome.
