title: Antibiotic therapy for arterial infection: lessons from the successful treatment of a mycotic femoral artery aneurysm without surgical reconstruction.
abstract: A mycotic femoral artery aneurysm developed in a diabetic man with bacteremia from a Staphylococcus aureus urinary tract infection. Because of severe concomitant congestive heart failure and hypothyroidism, surgical reconstruction of the femoral artery was deferred while the patient received an intensive course of intravenous nafcillin. This led to stabilization of the size of the femoral aneurysm for two years, during which time it remained asymptomatic. Three such cases of nonsurgical treatment of a mycotic aneurysm have been documented. Surgical ligation, drainage, and bypass remain the mainstay therapies for mycotic aneurysms, but these cases demonstrate the possibility of sterilizing a primary arterial infection under the highly selected circumstances of an exquisitely sensitive organism, absence of periarterial abscess and readily observable anatomic location. Most importantly, these cases provide assurance that a six-week course of parenteral antibiotics is a reasonable adjunctive treatment for residual endovascular infection.
