What Is a Deep Vein Thrombosis (DVT)?

• A DVT is a blood clot that forms inside a vein. It may partially or completely block blood flow or, break off and travel to the lung. This is different from clots in superficial veins, where clots rarely break off.
• A DVT usually involves the lower legs (calves) or lower abdomen, but occasionally affects other veins in the body.
• It is most common in persons over age 60.

What Are the Signs & Symptoms of DVT?

• Sometimes no symptoms
• Swelling and pain in the area drained by the vein, usually the ankle, calf or thigh. Swelling in the leg includes everything below the clot, extending to the toes.
• Tenderness and redness of the affected parts
• Soreness or pain when walking. The soreness does not disappear with rest.
• Pain when raising the leg and flexing the foot (sometimes)
• Fever (sometimes)
• Increased heartbeat (sometimes)
