Histoplasma infection of aortofemoral bypass graft.

Histoplasma infection of vascular grafts is extremely rare. To our knowledge, there are only 4 cases reported with Histoplasma capsulatum infection of the aortic graft. All had previous disseminated histoplasmosis and atherosclerotic peripheral vascular disease. They were treated surgically with explantation of the infected graft and reimplantation of new graft in extra-anatomic uninfected site. The authors present a new case of H capsulatum infection of aortofemoral bypass graft, but unlike the other cases, this case was managed without surgical intervention.
