DVT & Air Travel

 


Air Travel and Deep Vein Thrombosis DVT

Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. It may develop if you have certain medical conditions that affect how your blood clots. Deep vein thrombosis can also happen if you don't move for a long time, such as after surgery, following an accident, or when you are confined to a hospital or nursing home bed. (MayoClinic 2016)

In light of recent cases that point to a seemingly apparent correlation between air travel, and blood clot related trauma, we deem it appropriate to educate as many people as possible about this potential health threat, so as to prepare accordingly. 

Symington and Stack first pointed out a possible relationship between DVT & air travel (it was dubbed “Economy Class Syndrome). The incidence was attributed to cramped seating in the coach cabin. Prolonged periods of inactivity caused by space limitations may slow circulation and produce edema (leg swelling). In addition, bent knees compress the popliteal vein (the deep vein behind the knee), creating a potential site for clot formation over time. Low oxygen, low humidity (dry air), and low cabin pressure at high elevations have a dehydrating effect that concentrate the blood, making it sluggish. This effect is worsened when passengers consume alcohol, or do not adequately replenish fluids lost by dehydration.

www.airhealth.org  is a non-profit organization dedicated solely to the topic of travel-associated thrombosis, reports that 3-5% of air travelers will develop clots. 

Until it is clarified whether airline travel is or is not a risk factor for thrombosis it appears appropriate for travelers to engage in some DVT prophylaxis exercises, be well hydrated, and avoid alcoholic beverages during flights (Stoptheclot.org, 2016).
