Haemocompatibility and thrombogenicity

Platelet adhesion


Site of vessel injury:

  • Platelet glycoprotein Ib (GP Ib) and exposed connective tissue e.g. collagen
  • Requires plasma von Willebrand factor (vWF) as an essential cofactor

Artifical surfaces:

  • Via above mechanism
  • GP IIb/IIIa
  • Receptor for fibrinogen, vWF, fibronectin, vitronectin
