Abstract

Infectious aneurysms in hemodialysis patients are very rare. It is assumed that injuries on atherosclerotic vessel walls are involved in the development of aneurysms associated with septicemia. Rupture of infectious aneurysms carries a high mortality rate because it often leads to hemorrhagic shock. Here we report the case of a hemodialysis patient with rupture of an abdominal aortic infectious aneurysm secondary to Staphylococcus aureus septicemia. A 72 year-old male hemodialysis patient presented with diarrhea and fever. Staphylococcus aureus was identified in his blood culture. On the sixth day after admission, he developed sudden abdominal pain, distension and hypotension, so we assumed hypovolemic shock due to intraabdominal hemorrhage. On abdominal CT, he was found to have a ruptured, 2.4x2 cm infrarenal abdominal aortic aneurysm with a large amount of retroperitoneal hemorrhage. His final diagnosis was rupture of an infectious aneurysm based on the presence of Staphylococcal bacteremia. He underwent a percutaneous stent graft in the infrarenal aorta successfully. However, two weeks later, he developed septic shock due to a newly developed intestinal perforation and died of multiorgan failure.
