Management of vascular prosthetic infections: results of long-term follow-up.

An infected vascular prosthesis is a risk to life and limb, with many of the infections insidious in nature. A retrospective analysis with a minimum 49-month follow-up identified 18 patients (mean age, 61.3 years) with culture-positive infections and exposed prosthetic grafts in the infrainguinal region. All patients were managed with muscle flaps. Mean follow-up was 59 months, with a long-term salvage of infected prosthetic grafts in 16 of 18 patients; there was no loss of life or limb. Early, aggressive reconstruction of infected prosthetic grafts using a muscle flap technique saves graft, leg, and patient.
