  1. Intramural thrombi of heart
    overlie the M.I.
  2. Valvular thrombi of heart
    mimic endocarditis
  3. arterial thrombi
    • attach to walls
    • causes atherosclerosis
    • can be found in aneurysms
  4. venous thrombi
    • in dialated veins
    • - poor return
    • -standing all day
  5. microvascular thrombi
    • typical of disseminated intravascular coagulation (DIC)
    • --> systemic, clotting system going crazy, inappropriate clots, many causes

    amniotic fluid emboli -> postpartum DIC
  6. Deep Venous Thrombosis (DVT)
    Predisposed by Virchow's Triad

    can lead to pulmonary embolism ( elderly on flights)
  7. Virchow's triad
    • 1. Stasis
    • 2. Hypercoagulability (other inflam. events going on at the same time)
    • 3. Endothelial damage - clot head upstream and get caught
  8. embolism
    blockage
  9. White/pale imfarct
    typical of arterial occlusion
  10. Red/hemorrhagic infarct
    venous obstruction

    -intestines and testis
  11. Shock
    3 possible mechanisms
    decrease C.O.

    • 1. Pump failure (cardiogenic shock)
    • 2. Loss of fluid from circulation (hypovolemic)
    • 3. Loss of periph. vascular tone (hypotensive)
  12. Symptoms of shock
    • hypotension
    • edema
    • oliguria
    • dyspnea
  13. Stages of shock
    • 1. Early/compensated shock
    • 2. Decompensated but reversible
    • 3. Irreversible
  14. Compensated
    • Tachycardia
    • Vasoconstriction
    • reduced urine production
  15. Decomp reversible
    • hypotension
    • tachypnea, SOB
    • Oliguria
    • Acidosis
  16. Irreversible Shock
    • Circulator Collapse
    • hypoperfusion of organs
    • loss of vital fxns
  17. Massive hemorrhage
    • <500 ml - homeostatic compensation
    • 1-1.5L - circulatory shock
    • >1.5 L - Lethal
  18. hematoma
    tissue compression
  19. intracerebral hemorrhage
    stroke, death
  20. chronic hemorrhage
    slow blood loss, iron deficiency
  21. Exudate Edema
    • high protien/blood cells
    • Inflamation
    • gravity >1
  22. Transudate edema
    • less protein/cells
    • typical of hydrostatic or osmotic pressure pathology
    • gravity <1
