Etiology
Classically, thrombosis is caused by abnormalities in one or more of the following (Virchow's triad):
- The composition of the blood (hypercoagulability)
- Quality of the vessel wall (endothelial cell injury)
- Nature of the blood flow (hemostasis)
The formation of a thrombus is usually caused by the top three causes, known as Virchow's triad. To elaborate, the pathogenesis includes:
- an injury to the vessel's wall (such as by trauma, infection, or turbulent flow at bifurcations)
- by the slowing or stagnation of blood flow past the point of injury (which may occur after long periods of sendentary behavior - for example, sitting on a long airplane flight
- by a blood state of hypercoagulability (caused for example, by genetic deficiencies or autoimmune disorders).
High altitude has also been known to induce thrombosis [3][4]. Occasionally, abnormalities in coagulation are to blame.
Intravascular coagulation follows, forming a structureless mass of red blood cells, leukocytes, and fibrin.
