7. Real Coagulation
• Cell mediated, not chemical mediated
• Platelets are most important
• Platelets form plug (thromboxane)
fibrin surrounds (classic coagulation)
RBCs get stuck
9. Real Coagulation - Arterial
• high shear
• plaque builds up in media of arteries
• plaque ruptures followed by massive platelet activation
• typical cell mediated clot forms
13. Summary
• Coagulation – model versus real
• Anticoagulation – normal, pathologic, prevention
•The most common problem leading to
postoperative bleeding is silk
deficiency.
