Abstract
Sudden thrombosis of an abdominal aortic aneurysm (AAA) is distinctly rare and is associated with up to 50% mortality. Almost equally rare is infection of a preexisting AAA. We report an extremely unusual case of an AAA that thrombosed leading to acute limb ischemia. This was followed several months later by a delayed rupture of the thrombosed AAA associated with an Escherichia coli infection. We suspect the aortic thrombus was hematogenously seeded by a urinary tract infection. A review of the literature revealed that bacterial infection of a previously thrombosed AAA, leading to a delayed rupture, has not been previously reported.
