TIA Stroke Risk & Plane Travel

Transient ischemic attack, or TIA, refers to a mini stroke with symptoms similar to stroke, but without the associated damage. The American Heart Association says more than a third of those who have experienced a TIA will suffer a stroke.

  1. Plane Travel

    • Prolonged immobilization increases the risk of developing blood clots known as deep vein thrombosis. These clots can lead to pulmonary embolism and usually do not cause strokes; however, a 2003 study by the American Academy of Neurology found that in people with an opening between two heart chambers, the clot can enter the arteries of the brain and cause a stroke. This opening is present in about 30 percent of the population and most people are unaware of its presence.

    Prevention

    • People with previous TIA episodes are more vulnerable to strokes and should take extra care when traveling by plane. Preventative measures focus on preventing blood clots.

    Increasing Blood Circulation

    • Elastic compression stockings apply pressure to the legs and support blood circulation, which helps to prevent blood clots. If possible, frequently walk up and down the aisle. Many flexing exercises can be performed while in a seat.

    Hydration

    • Dehydration causes the blood to become more concentrated and susceptible to clotting. The AHA recommends drinking extra water and avoiding alcoholic beverages on flights.

    Blood Thinners

    • Blood thinners prevent the formation of blood clots. High-risk patients might benefit from a dose of blood thinners before plane travel.
