Overview
The presence or an absence of a risk factor plays a major role in the assessment of the pretest probability of DVT. Furthermore,
- Short-term anticoagulation is reruired for transient risk factors.
- Long-term anticoagulation is given where the cause is unknown or chronic or presence of persistent risk factors.
Risk factors:Inherited vs Acquired
Risk factors can be broadly classified in two categories, which are:
- Inherited thrombophilia: which include the following disorder
- Factor V Leiden mutation
- Prothrombin gene mutation
- Protein S deficiency
- Protein C deficiency
- Antithrombin (AT) deficiency
- Acquired disorders
- A previous history of DVT (most significant risk factor).[1]
- Injury to a deep vein from surgery, fractured bone, or other trauma.
- Prolong Immobilization : It slow down the blood flow in a deep vein. This may occur after surgery, if you're ill and in bed for a long time, or if you're on a long flight.
- Pregnancy and the first 6 weeks after giving birth.
- Recent or ongoing treatment for cancer.
- A central venous catheter, a tube placed in vein to allow easy access to the bloodstream for medical treatment.
- Age>60 (although DVT can occur in any age group).
- Being overweight or obese.
