Sudden intravascular coagulation disease due to air travel, which was first described in 1954, was named "Economy class thrombosis" in 1977. Nowadays, it is called Travelers Thrombosis. Research on flight embolism, which was detected in a young passenger who died due to pulmonary embolism after a long flight, shows that the probability of deep vein thrombosis is approximately 5-10% in flights lasting more than 4-5 hours, and that this potentially fatal disease is caused by compression stockings worn during the flight, in risky passengers. It can be prevented by low molecular weight heparin injections a few hours before the flight. Long train and especially bus journeys can also have the same effect due to inactivity in the legs and cause clots in deep veins. Although bus journeys can last a long time, due to frequent breaks, the risk is higher than that of air travel. However, all journeys without a break for more than 4 hours can lead to sudden intravascular clotting, the mildest of which is superficial vein clotting called thrombophlebitis, deep vein thrombosis as a more serious disease, and finally pulmonary embolism, which can be fatal.
The most common and dangerous vascular disease under this main heading is deep vein thrombosis (intravenous clotting) occurring in the legs. The most serious consequence of this disease, which is more common in those with varicose veins and venous insufficiency disease, is Venous Thromboembolism (intravenous clot traveling to distant organs). What makes deep vein thrombosis an important disease are the two serious complications it causes.
The first of these is pulmonary embolism (lung embolism), which occurs in the acute period, while the other is postthrombophlebitic syndrome, which occurs in the long term. If deep vein thrombosis is left to its natural course after it develops, pulmonary embolism, a fatal complication, occurs. The main culprits of this urgent and fatal condition caused by a vein clot in the leg are stasis (slowdown in blood flow), damage to the vessel wall, and hypercoagulability (tendency to clot) in the blood. At least one of these criteria is sufficient to increase the risk of thrombosis.
Mostly enlarged varicose veins and venous insufficiency Poverty charts pave the way for a slowdown in circulation. Prolonged inactivity can cause vein thrombosis even in seemingly healthy people. It is considered risky to remain inactive during a plane journey of more than 4 hours, or during a non-stop car, train or bus journey of more than 6 hours. In these people, the possibility of deep vein thrombosis increases during the trip or within 4 weeks afterwards.
Immobility in the legs of passengers as a result of narrow plane and bus seat rows, changes in cabin pressure in planes, low humidity in the environment, drinking less water, i.e. Acute and chronic dehydration, diuretic tea, coffee and alcoholic drinks taken before and during the journey cause the liquid part of the blood to decrease and invite venous thrombosis. Especially in those sitting near the window and in the middle seats on airplanes, the possibility of deep venous thrombosis and pulmonary embolism is on the aisle side. more than sitting people. 85% of cases with venous thrombosis are seen in people sitting in seats outside the aisle. The risk of thrombosis after a flight of more than 4 hours is much higher than in flights under 4 hours. If the bus journeys are long, you should definitely walk at the rest stop for at least 5 minutes during each break, and take breaks during the journey. The foot should be moved in a manner similar to walking. But most importantly, if there is the slightest sign of varicose veins and venous insufficiency, the disease should be treated for preventive purposes according to the results of the examination and Doppler Ultrasound examination to be performed by the Cardiovascular surgeon.
Long. During bus, train and plane journeys, especially passengers with varicose veins and all pregnant women should drink plenty of water and wear compression socks. During long plane journeys, in addition to these, low molecular weight heparin type blood thinner drug protection should be applied in consultation with experts.
