title: Experimental microarterial grafts: the use of freeze-dried human placental vessels as heterografts.
abstract: Freeze-dried human placental grafts, when grafted onto the rabbit femoral artery, have a patency rate of 85 percent at 2 weeks that drops to 55 percent at 3 months. Histologic and scanning electron microscopic studies show that the original graft disintegrates and is replaced by a new fibrous layer on top of it.
