Fig. 1 Photomicrographs of regular (30 μm) ePTFE graft from animal sacrificed at 120 days. Section of midportion of graft is shown (lumen is at top of each photo). There is paucity of cellularity in graft in both hematoxylin-cosin (A) and Masson trichrome (B). Minimal incorporation into surrounding tissues is also noted. (Original magnification × 200.)

Fig. 2 Photomicrographs of thin-walled (60 μm) ePTFE graft at 60 days (A) and carbon-coated, thin-walled ePTFE graft (B) from animal killed at 120 days. Both grafts demonstrate extensive fibroblastic incorporation of grafts with marked cellularity. This is in contrast to regular (30 μm) graft. (Masson trichrome; original magnification × 200.)
