We describe a 50-year-old man with von Willebrand disease type 2A who suffers from angiodysplasia and has required many transfusions for gastro-intestinal haemorrhage. Various investigative modalities have not demonstrated a single source for this. Following a case report of successful use of recombinant activated factor VII (NovoSeven; Novo Nordisk, Copenhagen, Denmark), the patient was treated with it but suffered a large myocardial infarct. As the patient has risk factors for atherosclerotic disease, we presume the recombinant activated factor VII promoted coagulation at a pre-existing atherosclerotic lesion.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
