Deep Vein Thrombosis 

What Is Deep Vein Thrombosis? 

If blood moves too slowly through your veins, it can cause a blood clot. A blood clot is a collection, or mass, of blood cells. When this happens in a vein deep inside your body, it is called deep vein thrombosis, or DVT.

DVT is a serious condition because it can hinder blood flow. It requires treatment right away. The expert team at Emory Heart & Vascular can help. 

Causes of Deep Vein Thrombosis 

DVT can happen when you have damage to a vein. Infection, inflammation, injury or surgery can damage your veins.

Your chance of getting DVT is higher if you have cancer, heart disease, inflammatory bowel disease or an inherited blood disorder. The risk for this condition also is greater for people who are:

  • Smokers
  • Obese
  • On bedrest or very sedentary
  • Over age 40
  • Pregnant
  • Related to individuals who have had DVT
  • Taking birth control pills

Sometimes, DVT can occur without any identifiable risk factor.

Emory Heart & Vascular experts offer many treatments for DVT, including a specialized filter to catch clots before they reach your lungs.

Symptoms of Deep Vein Thrombosis 

Most deep vein blood clots occur in the thigh or calf. But they can also appear in other areas of the body, such as the pelvis or arm. Symptoms include:

  • Enlarged veins
  • Skin that appears red, blue or purple
  • Swelling, pain or warmth in the area

DVT also may occur without any noticeable symptoms. If you think you may have DVT, call your doctor right away.

Complications of Deep Vein Thrombosis 

If a blood clot moves from the vein to the bloodstream, it can get stuck in a blood vessel in the lungs. This is called pulmonary embolism (PE). PE blocks blood flow and can be life-threatening.

Symptoms of PE include:

  • Chest pain
  • Coughing up blood
  • Dizziness, lightheadedness or fainting
  • High heart rate
  • Rapid breathing
  • Shortness of breath

If you have symptoms of a pulmonary embolism, you will want to call your doctor and get medical care immediately.

Diagnosing Deep Vein Thrombosis 

Your doctor will first examine your body and look for signs of DVT. They may also do other procedures such as:

  • Blood test: To check levels of a protein produced by blood clots
  • Duplex ultrasound: To scan the body for blood clots
  • MRI: To look for DVT in the abdomen
  • Venography: Rarely used, but shows how blood flows through your veins
