What Is Deep Vein Thrombosis?
Deep vein thrombosis (DVT) is a blood clot that develops in the deep and larger veins in one or both legs, usually in the lower leg (figure shows DVT in the left thigh). DVTs can be dangerous because the clot may become large, break apart, and go through the blood vessels and lodge in the lungs, resulting in decreased or no blood flow to the lungs. This situation may lead to rapid organ damage and even death.

DVT Dangers: Pulmonary Embolism
Many DVTs are not detected by patients or their doctors; about half have no warning signs. Symptoms, when present, may include one or more of the following:
Edema in the affected leg (most specific symptom), with possible skin blanching
Leg tenderness, sometimes with a palpable bump or mass
Leg pain
Leg warmth and/or leg skin redness over the DVT
Lung symptoms of pulmonary edema (PE), a complication of a DVT
A positive Homan’s sign (calf pain when foot is flexed upwards)
