Arterio-venous fistulas constructed with formalin-fixed human umbilical grafts.
Since July 1976 we have implanted 18 umbilical vein grafts as haemodialysis shunts. Our experience shows that the umbilical vein is suitable for all shunt localisations. The formalin-fixed umbilical vein graft can be considered for vascular replacement. These can be removed in any clinic, prepared and stored under sterile conditions. The formalin conservation procedure is simple, inexpensive and possible everywhere without elaborate technical equipment.
