The objective of this study was to evaluate the effectiveness of cryopreserved arterial homografts for management of prosthetic graft infection. Between October 1992 and July 1998, 90 patients (84 men) with a mean age of 64 years from six different hospitals were treated for prosthesis infection by in situ replacement using a cryopreserved arterial homograft (CAH). In 43 patients (47%), the primary procedure had been performed at a nonparticipating center. Prosthetic graft infection occurred early (i.e., within 1 month after the primary procedure) in 15 cases and late in 75 cases. In the late group, the mean interval between the primary procedure and CAH replacement was 34 months (range, 3 to 330 months). In 41 patients, infection was located in the aortic region, including 17 presenting with enteroprosthetic fistula (EPF). In 49 patients, infection was confined to the femoral, popliteal, or subclavian region. Bacteriologic cultures were positive for one or more germs in 75 patients and negative in 15. The surgical procedure consisted of complete or partial removal of the infected prosthetic graft, debridement, and in situ reconstruction using one or more CAH. Our results showed that management of prosthetic graft infection, a grave complication, using a CAH is a promising technique, especially for patients in stable condition prior to reconstruction.
