Long plane trips increase risk of venous thromboembolism – Jurnal diariOnline South Region


NEDVP gives recommendations to prevent blood formation

The Portuguese Society of Internal Medicine (SPMI) Center for Pistol Disease Studies (NEDVP) alerts the population to the increased risk of venous thromboembolism during and after prolonged airway transport. It is estimated that 3.2 out of every 1,000 people exposed to this scenario annually suffer from this problem.

"The risk of developing venous thromboembolism is greatest when the journey lasts more than four hours and within two weeks immediately after the trip, gradually reducing to the next eight weeks.", highlights Ana Oliveira Gomes, a member of the NEDVP Secretariat.

According to the internist, “Long trips favor this condition, which includes pulmonary embolism and deep vein thrombosis. Deep vein thrombosis occurs when thrombosis or blood is formed in the veins of the legs. If this rocket is split or fragmented, it can travel to the lungs and cause a pulmonary embolus. "

Risk factors for this health problem are a history of previous venous thromboembolism, active neoplasia, recent surgery or trauma, reduced mobility, advanced age, thrombophilia, pregnancy and postpartum, use of estrogen medications such as the pill or hormone therapy. menopause replacement, height more than 1.85 meters or less than 1.65 meters, and obesity.

In order to prevent venous thromboembolism, NEDVP makes some recommendations that should be taken while traveling by plane: “Get up and walk every hour or two; exercise or stretch your legs regularly; avoid tight clothing; drink water and avoid drinking alcohol or sedative pills. "

In recent years, the Center for Studies of Lung Disease has developed several educational materials on venous thromboembolism targeted at the population. These can be viewed by clicking here.
