Travel Health Tips for Deep Vein Thrombosis [infographic]

Quick Facts About DVT

Deep Vein Thrombosis (or DVT) is a condition where a clot, or clots, form in one or more of the deep veins, usually in the legs.

• The risk for blood clots increases by 10% for every hour spent sitting.
• Blood clots can cause partial or complete blockage of venous circulation, or break free and cause a life-threatening condition.
• Extended immobility during travel increases DVT risk by 2-4x.
• Approximately half of all cases occur without any noticeable symptoms.

Risk Factors for DVT

• Risk increases with age ( > 40 years old)
• Overweight (BMI > 30)
• Estrogen (birth control pills)
• Pregnancy
• Thrombophilia (an abnormally increased tendency to create clots)
• Active cancer
• Serious medical illness
• History of Venous Thromboembolism (VTE)
• Recent surgery, hospitalization or trauma
• Limited mobility
• Central venous catheterization

DVT Symptoms

• Swelling in the affected leg, ankle, and foot
• Pain in the calf that spreads to the ankle and foot
• Warmth over the affected area
• Redness or discoloration of the skin

Prevention of DVT

• People who are predisposed to, or have previously suffered DVT should wear compression socks and consult their primary care providers regarding possible benefits from medication.
• Avoid long periods of immobility. Stand up and walk around, exercise your feet and calves.
• Stay well hydrated, avoid alcohol.

Treatment of DVT

• Anticoagulants (aka blood thinners) to prevent clotting
• Filters (aka umbrella) prevent clots that break loose from going to the lungs
• Compression socks and stockings prevent swelling reduce the formation of blood clots

Recommendation if DVT is suspected while traveling: MEDICAL ATTENTION IS NEEDED

Clots that break free will travel upstream and may cause a pulmonary embolism, which could be life-threatening and require immediate treatment. In remote locations, an emergency medical evacuation may be needed.
