Deep-vein thrombosis (DVT) is a relatively common and serious medical condition that occurs in approximately 2 million Americans each year. DVT occurs when a blood clot (which is also called a thrombus) develops in one of the large veins, usually in the legs, leading to either partially or completely blocked circulation. This may lead to complications, such as a pulmonary embolism and even death if not diagnosed and treated effectively.
Only about 50% of people experience symptoms when they have DVT. Symptoms of DVT may include:
Discoloration or redness of the affected area
Skin that is warm to the touch
Who is at risk?
DVT can occur in almost anyone. Certain individuals may be at increased risk for developing a DVT. Some of the risk factors for DVT include:
Restricted Mobility (like when on a long plane flight)
Congestive Heart Failure
Age > 40
Smoking (especially in women taking oral contraceptives)
