ABSTRACT
Other factors have been shown to increase risk o f aortic graft infection including reoperative or emergent surgery, prolonged hospital stay or operating time, and colonic ischemia after surgery. The graft material itself has been suggested to play a role as well. Knitted Dacron may be less susceptible to infection than woven grafts in experimental animal models, and both may be more susceptible than PTFE. Data in humans, however, has not clearly demonstrated this to be true.
