Clotting

Clotting disorders

Blood clots can occur in the artery or veins. 

Strokes and heart attacks are due to blood clots occurring in the arteries. 

Blood clots occurring in the veins are called venous thromboembolism (VTE) - if it occurs in the legs, it is called deep vein thrombosis (DVT) and if it occurs in the lungs, it is called pulmonary embolism (PE). In most cases of PE, the clot originates from the lower limbs and may lead to death.

The risk factors that are associated with DVT and PE are: 
  •  Cancer
  •  Pregnancy
  •  Surgery – pelvic, orthopedic, abdominal
  •  Immobilization e.g. stroke, leg fracture in a cast
  •  Family history of VTE
  •  Antiphospholipid syndrome

If you have the following symptoms, please see a doctor urgently:

Deep vein thrombosis
  •  Pain
  •  Leg swelling – especially on one leg
  •  Redness
  •  Warmth 
  •  Tenderness

Pulmonary embolism
