Preclotting of knitted Dacron prosthesis. A scanning electron microscope study

R G Guidoin et al. J Thorac Cardiovasc Surg. 1975 Jul.

Abstract

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).
