Deep Vein Thrombosis (DVT)
Deep Vein Thrombosis (DVT)
Is the occurrence of a clot in the veins of the legs with possible complication of the clot spreading to the lungs (pulmonary embolism).
Long distance travel increases the risk of DVT, irrespective of the mode of travel.
Causes
- Prolonged immobility in confined spaces.
- Additional risk factors specifically related to air-travel.
Why is it dangerous?
If a fragment of the clot breaks off, it may travel via the circulation and lodge in the lungs. This can cause cardiogenic shock and abnormal heart rhythm – both of which are life-threatening.
What are the symptoms of DVT?
Painful swelling of the calf which may extend into the ankle and foot.This may be difficult to differentiate from a muscle spasm.
If the clot spreads to the lungs, the symptoms may not be specific but may include:
- Chest pain.
- Coughing up blood.
- Difficulty breathing.
Do’s
- Move about the aircraft regularly
- Avoid restrictive clothing around the legs and waist.
- Flex and relax leg muscles regularly while seated.
- Remain well hydrated.
- Specific medication may be used on the instruction of your Go Health professional should you be at increased risk.
Don’t
- Drink liquids high in caffeine or alcohol.
- Aspirin is not recommended.
