Fig. 2 SEM photomicrographs of an ePTFE graft implanted for 2 months. A, Proximal anastomosis with aorta (Ao) and prosthesis (P) (× 60). B, Endothelial-like coating just below the proximal anastomosis, with one leukocyte; the luminal surface is devoid of S. aureus (× 1100).

Fig. 3 SEM photomicrographs of the middle portion of an ePTFE graft implanted for 2 months. A, Luminal surface is poorly healed with packed and loose fibrin (× 860). B, Numerous S. aureus are trapped in the loose fibrin (× 4000).
