False aneurysm infected by Aspergillus fumigatus: an unusual complication of aortofemoral bypass graft.

ABSTRACT

Two cases of Aspergillus fumigatus infection of aortobifemoral prosthetic grafts are reported. Both patients were treated successfully by excision of the infected prosthetic material, axillofemoral extra-anatomic bypass, and prolonged medical treatment. The patients received amphotericin B, 5-flucytosine and itraconazole until negative aspergillus serology was obtained (at 9 and 18 months, respectively). Later, repeat disobliteration procedures for thrombosis of the axillofemoral bypass were required. No recurrent aspergillus infection was found.
