A scanning electron microscope study of preclotting on knitted Dacron
prosthesis is reported. Five steps of the interaction are well identified:
(1) before any blood contact (virgin Dacron), (2) during the first 3
minutes (fibrin and platelet aggregates), (3) fifth minute of contact
(clotting), (4) 15 minutes of contact with heparinized blood (thin fibrin
network), and (5) the following minutes (invasion of fibrin, which enmeshes
blood cells).
