Abstract: | We report a case of mycotic abdominal aortic pseudoaneurysm caused by a penetrating atherosclerotic ulcer (PAU). An 81-year-old woman was admitted to a local hospital with fever and abdominal pain, and when her symptoms were not improved by antibiotics, she was referred to our department. Computed tomography (CT) and angiography showed a saccular aneurysm below the renal arteries, and an emergency laparotomy was performed because we suspected a mycotic abdominal aortic pseudoaneurysm. An abscess was found on the proximal side of the jejunum, caused by an aneurysm penetrating the serosa. We diagnosed a mycotic pseudoaneurysm after finding the anterior wall of the aorta penetrated by intense calcification. The pseudoaneurysm was resected with the abscess and the area was covered with a pedicled omental flap to prevent infection. An axillofemoral bypass was also done. The patient recovered well. |
