Local activation of blood coagulation by polyester prostheses implanted into defects of the abdominal aorta of dogs.
An 8 cm long Dallon prosthesis was implanted into defects of the abdominal aorta of dogs, and the following changes were found: the blood flow through the vascular prosthesis induced a shortening of the blood clotting time and the heparin-thrombin time and a slight increase in the prothrombin consumption. It has a favourable effect of the sealing of pores in the prosthesis and covering its internal surface with a fibrin membrane.
