Early detection and treatment of deep vein thrombosis (clots of the legs) can reduce the risk of pulmonary embolism.

To reduce your risk after surgery, your doctor may encourage you to walk and start some activity.  Other ways to prevent clotting may include leg exercises and compression stockings. As well, low doses of heparin injected under the skin (subcutaneous heparin therapy) may be used for people who have to stay in bed for a long time.

Prevention while traveling

The risk of getting a blood clot while you travel is low. However, anyone traveling more than four hours, whether by air, car, bus, or train, may be at risk for blood clots. While you travel move your legs frequently and exercise your calf muscles. When possible take a break from sitting to stretch your legs. Some airlines will have exercises you can do in the magazine in your seat pocket.
