Abstract
Infected abdominal aortic aneurysms (IAAs) are rare, and their surgical treatment remains difficult. We describe a rare case of effective surgical treatment for an IAA patient with spondylitis. The surgical treatment of choice for IAA with spondylitis is considered to be extra-anatomical bypass. We performed in-situ reconstruction using rifampicin-bonded gelatin-impregnated Dacron grafts and covered the prosthesis with the omental flap. Spondylitis is difficult to diagnose because its symptoms can be similar to those of IAA, and moreover, imaging is difficult in the early stages.
