Interaction of vascular grafts with the host tissue(× 200). Black arrows indicate vascular grafts, and white arrows indicate in-grown tissue. (A) A PU graft harvested 4 weeks after the surgery showing limited ingrowth of fibrous tissue. (B) A PTFE graft harvested 4 weeks after the surgery showing more extensive ingrowth of fibrous tissue. (C) A PU graft harvested 24 weeks after the surgery still showing limited ingrowth of fibrous tissue and no neointima thickening. (D) A PTFE graft harvested 24 weeks after the surgery showing substantially increased tissue infiltration and increased thickness of neointima.
