We describe successful resection and anatomical revascularization in 2 men aged 75- and 50 who suffered from prolonged systemic infection. Blood culture was positive in both cases, Klebsiella pneumoniae and Staphylococcus aureus (MSSA), respectively. Case 1 was misdiagnosed as acute appendicitis and underwent laparotomy. Postoperative CT revealed leaking aneurysm. Case 2 was diagnosed correctly on screening CT. Bacterial culture of all surgical specimens proved negative. The postoperative course was fortunately uneventful. The early and accurate diagnosis of infected aneurysm is important to establish surgical strategy. Timing of surgical intervention is still difficult to determine for minimizing the risk of graft infection.
