Novel extra-anatomic intra-abdominal reconstruction for treatment of paravisceral aortic infection

Abstract

Adequate treatment of native or prosthetic aortic infection requires extensive surgical debridement and establishing flow to the extremities using extra-anatomic or in situ reconstruction, each with its inherent limitations. Infection of the paravisceral aortic segment precludes an axillofemoral bypass as the sole treatment because of inability to provide visceral perfusion. In situ autograft or allograft reconstructions could be limited by conduit availability or significantly prolonged operative time, or both. Placement of an antibiotic-soaked prosthetic in a field with gross purulence carries a high risk of reinfection. We describe a technique for extra-anatomic, intra-abdominal reconstruction using an antibiotic-soaked prosthetic graft to avoid the infected paravisceral aortic bed and achieve antegrade lower extremity and visceral vessel perfusion.
