Blood Clots and Travel Wednesday, July 8, 2009 7:51 AM



Many people will be traveling this summer, including those with Lymphedema.  Here are a few things to
remember about travel and DVT, from MD Travel Health.

Deep vein thrombosis
.
Blood clots may form in the legs (deep vein thrombosis) during long plane flights, chiefly because of
prolonged immobility. The longer the flight, the greater the risk. The risk is greatest for flights longer than
8-10 hours. Blood clots can also form after long train or car rides. Though most blood clots are reabsorbed
uneventfully, some may dislodge and travel through the blood vessels to the lungs, where they may obstruct
blood flow and cause life-threatening complications.
Risk factors for deep vein thrombosis include
previous history of deep vein thrombosis
chronic swelling of the legs or feet
varicose veins
pregnancy
use of estrogen or raloxifene (Evista)
advanced age
cancer
obesity
stroke
recent hospitalization or surgery
To prevent the development of blood clots on long plane flights, the following measures are recommended:
Wear comfortable, loose-fitting clothing.
Do not place hand luggage where it may limit leg movement.
Walk about the cabin at regular intervals.
Perform isometric compressions of the leg muscles (i.e. contract the leg muscles periodically while sitting).
Avoid crossing your legs.
Drink plenty of fluids.
Avoid alcohol and tobacco.
For those with any of the above risk factors, wear compression stockings, which can be purchased in most
drug stores.
Low molecular weight heparin may be considered for those at particularly high risk for thrombosis.
The chief symptom of deep vein thrombosis is swelling of the foot, ankle, or calf on one side, sometimes
accompanied by pain. When the blood clot travels to the lungs, the chief symptoms are chest pain and
difficulty breathing. Travelers with any of these symptoms should immediately seek medical attention.
