Risk factors and outcomes for nosocomial infection after prosthetic vascular grafts.

SSI was the primary NI. The risk of NI depended primarily on the presence of a lower extremity SSTI at the time of surgery, whereas mortality was determined by age, surgical complications during the operation, and SSI. These findings suggest that in those cases in which surgery is reasonably delayed, surgery should be deferred until the lower extremity SSTIs are resolved.
