Emergency treatment of a salmonella-infected abdominal aortic aneurysm associated with spondylodiscitis

To report surgical treatment of a ruptured abdominal aortic aneurysm (AAA) associated with spondylodiscitis due to Salmonella in emergency setting.

A 69-year-old male with an history of hypertension, presented with a ruptured AAA infected by nontyphoidal Salmonella (type H), associated with spondylodiscitis. Patient underwent an emergency operation consisting in surgical debridment of infected tissue and aortic replacement with a prosthetic Dacron graft impregnated with Gentamycine. The postoperative course was uneventful and the patient was discharged at day 20 after the index procedure in good clinical condition. antimicrobial therapy was continued for 8 weeks. A CT scan and nuclear medicine studies performed two months later demonstrated minimal sign of residual aortitis. A CT scan 21 months after the procedure showed complete anatomic resolution of the disease.

A rare but increasing number of aneurysms as a consequence of Salmonellosis can be observed with a high rate of morbidity and mortality, mainly in patients with a concurrent infection of the spine and paravertebral tissue. Combined antimicrobial therapy and one-stage surgical treatment can be associated with good outcome.
