For those planning trips involving long haul flights, awareness of deep vein thrombosis is important.
Deep vein thrombosis (DVT) is a blood clot that develops within a deep vein in the body, usually in the leg. This condition can occur when traveling long distances by plane (or other vehicles), and with some airlines planning to reduce seat size further, the discussion of DVT has heated up recently. Although studies have yet to prove a link between seat size and the likelihood of DVT, it is nonetheless important for long haul travelers to have some knowledge of this affliction.
When deep vein blood clots occur, they can cause redness, swelling, localized pain or warmth to the touch. However, in some cases they can cause no symptoms at all. The danger of these clots is when pieces of them break off and travel through the bloodstream to the lungs, causing a pulmonary embolism (PE) which can be fatal. PE symptoms can include shortness of breath, chest pain, rapid heart rate, light-headedness or fainting. This is different from a stroke, in which clots block the arteries. When DVT and PE occur together it is called Venous Thromboembolism (VTE).
This condition is not only linked to air passengers, but in fact anyone who remains seated for prolonged periods, usually over 4 hours. It is in this situation when the risk of DVT increases. Think of sitting at a desk, in a car, on a train or on a bus.
For travelers, there are some ways to reduce the risk of DVT which can be considered when planning a trip.
