The aim of this work was clinical evaluation of impregnated (albumins) prostheses of Polish production. Those prostheses were compared with polyester knitted vascular prostheses. We evaluated a group of 48 patients to whom prostheses covered with albumins were implanted and 52 patients to whom nonimpregnated prosthesis was implanted in 1994-1997. The prostheses were implanted in aortofemoral segment. The achieved results prove the good quality of the impregnated prosthesis and its high value for vascular reconstructive surgery.
