[Straight upper arm arteriovenous implants of allogenic vascular transplant material in various hemodynamic conditions]

Studies were conducted into the effects of various forms of flow reduction upon both pressure in shunt and functional properties of 134 arteriovenous bridging grafts on the upper arm for haemodialysis of deantigenised, form-fixed, preserved segments of varicose veins with silicone-coated inner surfaces. Strongest pressure reduction and best clinical results were obtained from composite grafts with a short, narrow segment on the inflow side.
