Types of vascular grafts
Vascular grafts maybe biologic or synthetic. There are three categories of biologic grafts which are autologous grafts ,Allografts and heterografts .Autologous grafts (tissues taken from one part of the body and moved to another part .Allografts or homografts are tissue from one person transplanted into another .
Heterografts are tissues from another species that are transplanted into a human . Synthetic vascular grafts are produced from polyester or polytetraflouroethylene teflon ) with either woven or knitted structures, as parallel, tepered and bifurcated tubes. The grafts normally incorporate a coloured line along the lengh of the graft to assist the surgeon in avoiding introducing twist into the graft as it is implanted.
