Single-stage multidisciplinary management of contiguous infection involving infected abdominal aortic aneurysm and lumbar spondylodiscitis following infective endocarditis

Infective endocarditis can cause septic embolization and metastatic infections, including infected aortic aneurysm and spondylodiscitis. We report the case of a 77-year-old man with contiguous infection who was successfully treated using a single-stage multidisciplinary approach. Following antibiotic therapy that controlled the endocarditis, rapid expansion of an abdominal aortic aneurysm indicated impending rupture. Simultaneous surgery included in situ reconstruction using a rifampicin-soaked graft, infection-avoiding graft routing, spinal debridement, autologous bone reconstruction, and omental coverage. The patient recovered without recurrent infection. This case suggests that a single-stage multidisciplinary approach combining multiple surgical strategies may be an effective option for managing complex contiguous infections.
