Deep Vein Thrombosis (DVT) is a medical condition in which a blood clot forms within the deep vein. DVT most commonly occurs in the lower leg or thigh region. The latter include large veins, anatomically located under the deep fascia. It is a common disease that most commonly affects the leg veins and pelvis and can lead to pulmonary embolism (PE). DVT and PE are related, so they are often called venous thromboembolism (VTE). DVT can occur for several reasons, including damage to a vein, such as a fracture or surgery, or slow blood flow, such as lying in bed or sitting for long periods like a long flight.

However, in a few cases, it can occur in other parts of the body. Other risk factors include: Being pregnant, The use of hormone replacement for menopause or birth control pills, being overweight and having cancer. An inherited condition can increase your likelihood of forming clots or decrease your ability to dissolve them. DVT is considered a medical emergency that has to be treated on an emergency basis. If left untreated, it can be fatal.
