A 43-year-old woman was admitted with peripheral arterial occlusive di
sease (PAD), pelvis-type. The angiography showed a high-grade stenosis
of the aortal bifurcation. A percutaneous transluminal angioplasty (P
TA) in ''kissing-balloon-technique'' was performed. After 7 days the p
atient developed a sepsis with distinct back-pain. The ultrasound-B-sc
an and CT-scan of the abdomen showed the development of an infrarenal
aortic aneurysm during a period of 29 days. Bacterial infection of the
aorta was considered to be the reason of development of the aneurysm
occurred. Immediate antibiotic therapy got the patient afebrile after
14 days. We implanted an aortobiiliacal Dacron graft 2 weeks later. Th
e follow-up time was without complications except for two thrombotic o
cclusions of the graft after 4 and 19 months. Thrombectomy was carried
out in both cases without complications.
