Pathophysiology of Thrombosis and Embolism

Question 1

How can blood flow be abnormal?

Answer 1

Can be stasis or Turbulent

Question 2

Stasis blood flow?

Answer 2

Stagnant blood flow because something is obstructing the blood flows path.

Question 3

Turbulent blood flow?

Answer 3

Forceful and unpredictable blood flow

Question 4

What causes defects in blood flow?

Answer 4

• Commonly may be caused by thromboembolism
• Other causes includes: Atheroma, Hyperviscosity (blood is too thick), spasm of vessels, external compression (such as a tumour oppressing the blood vessel), vasculitis (inflammation of the blood vessel wall, vascular steal

Question 5

What is the Virchows Triad ?

Answer 5

This gives us answers on thrombolism and embolism. It includes

• Changes in blood vessel walls
• Changes in blood constituents
• Changes in pattern of blood flow
  Virchows triad gives the factors which cause thrombosis.

Question 6

What is thrombosis ?

Answer 6

Thrombosis is defined as a formation of a solid mass from the constituents of blood within the vascular system during life. It is in the VESSEL! It is not the same as clot

Question 7

Pathophysiology of thromosis?

Answer 7

Change in vessel wall will be causes by enfothelial injury. Then there should be stasis or turbulent flow. Hypercoagulity of the blood will be an important factor.
