[Experimental studies of vascular prostheses made of plastics with antibacterial properties].

Bilaterally velour, polyester vascular prostheses were soaked with antibiotics: vibramicin, gentamicin and riphamicin. To obtain more stable binding of the prostheses with the antibiotics, physico-chemical modification of its surface was made. The prostheses retained their bacteriocidal properties even after 120 hours of being in the arterial system of a dog. Experiments of animals show the prostheses are effective in fighting back experimental infection.
