Health Tip: Preventing Deep Vein Thrombosis

Deep vein thrombosis, or deep venous thrombosis, (DVT) is the formation of a blood clot (thrombus) within a deep vein, predominantly in the legs. Non-specific signs may include pain, swelling, redness, warmness, and engorged superficial veins. Pulmonary embolism, a potentially life-threatening complication, is caused by the detachment (embolization) of a clot that travels to the lungs. Together, DVT and pulmonary embolism constitute a single disease process known as venous thromboembolism. Post-thrombotic syndrome, another complication, significantly contributes to the health-care cost of DVT. Prevention options for at-risk individuals include early and frequent walking, calf exercises, anticoagulants, aspirin, graduated compression stockings, and intermittent pneumatic compression.

The risk is greater for flights over six hours in length, the risk of DVT is also increased for those with underlying risk factors such as a history of DVT, pregnancy, taking birth control pills, cancer (current or treated), a personal or family history of blood clotting abnormalities, recent major surgery, smoking, and obesity. The risk of DVT is very real and happens to many people:

  • Get comfortable in your seat and recline as much as possible
  • Do not wear tight clothing. Wear loose fitting clothing
  • Store your hand luggage in the overhead lockers to keep the room under the seat in front of you free
  • Bend and straighten your legs, feet and toes while seated every half-hour or so during the flight
  • Press the balls of your feet down hard against the floor or foot-rest to increase the blood flow in your legs and reduce clotting
  • Do upper body and breathing exercises to further improve circulation
  • Take occasional short walks around the cabin, while the aircraft is at cruising altitude
  • Take advantage of stopovers where it may be possible to get off the plane and walk about
  • Drink a reasonable amount of water
  • Avoid alcohol and caffeine, which in excess leads to dehydration and immobility
  • Avoid taking sleeping pills, which also cause inertia

The risk can be further decreased by wearing graduated compression stockings. You can usually find them for around $20 to $25. Do you have any of the following underlying risk factors for developing DVT?

  • History or symptoms of venous insufficiency
  • A family history of clotting conditions
  • An inherited tendency to clot (thrombophilia)
  • Cancer or had treatment for cancer in the past
  • Pregnant or taking birth control pills
  • Undergone major surgery in the last three months
  • Had hip or knee replacement within the last three months or
  • Ever suffered from a stroke

If you have any of these risks already, you should check with your doctor before ordering compression stockings. The doctor may suggest you wear stockings with a higher compression gradient. These stockings may require a prescription and custom fitting. If so, you can purchase these online and have your health insurance cover the cost if it is a covered benefit.

If you have no history of venous disease, you should consider wearing knee-high graduated compression stockings with 15 to 20 mm Hg compression gradient while on long airplane flights. These do not require a prescription, and can typically be purchased through local pharmacies or via the internet (but be sure you are purchasing graduated compression stockings and not simply support stockings or support hose).

    I appreciate that you included at risk behaviors or characteristics of people who might have deep vein thrombosis. I wonder if the condition is largely genetic or if it is caused by behaviors? I will be sure to apply some of your tips the next time I’m on a long light so I can avoid deep vein thrombosis.

    It’s interesting to read about some of the causes of deep vein thrombosis and how you can prevent it. My mom suffers from this quite severely and I think getting her the help she needs could be good. I’ll have to have her visit a vein specialist to see what she needs whether it’s surgery or just better sitting habits.
