Acting Surgeon General Steven K. Galson, M.D., M.P.H., has issued a
Call to Action to reduce the number of cases of deep vein thrombosis
and pulmonary embolism in the United States.
He says rising deaths from these conditions are unnecessary because treatment is available.
Deep vein thrombosis and pulmonary embolism affect an estimated 350,000 to 600,000 Americans each year, and the numbers are expected to increase as the U.S. population ages. Together, deep vein thrombosis and pulmonary embolism contribute to at least 100,000 deaths each year.
Deep vein thrombosis is a blood clot in a deep vein, most commonly in the lower leg or thigh. The clot can block blood flow and cause pain, swelling, and skin discoloration.
In the most serious cases, deep vein thrombosis can lead to a pulmonary embolism -- when part of the blood clot breaks loose and travels through the bloodstream to the lungs, where it can block a lung artery, causing damage to the lungs or other organs from lack of oxygen.
"Deep vein thrombosis and pulmonary embolisms are often 'silent' conditions -- they can occur suddenly and without symptoms," Galson said. "But we have made a lot of progress in understanding how these disorders develop and how to prevent, diagnose, and treat them. It's time to put this knowledge into action."
Researchers have found that in most cases, deep vein thrombosis and pulmonary embolism develops in people who have an inherited blood clotting disorder or other risk factor, and who experience a triggering event.
"Being hospitalized or confined to bed rest, having major surgery, suffering a trauma, or traveling for several hours can increase a person's risk of deep vein thrombosis and pulmonary embolism," Galson said. "We want to increase the awareness and knowledge of these potentially deadly conditions and encourage patients and health care providers to take the steps to prevent them."
