Blood Clots in Athens, Georgia

Athens, GA Blood Clots

What are blood clots?

When blood clots, it changes from a liquid to a solid. This is a normal part of the body’s response to an injury. Normal clotting occurs within seconds and helps limit blood loss by sealing damaged blood vessels when there is trauma. Normally, as the body heals, the blood clot dissolves and is reabsorbed. However, sometimes blood clots can block the flow of blood and oxygen through a blood vessel. The result can be a heart attack, stroke, loss of vision, blood clots in the lung, or other problems.

A blood clot that partially blocks a vein or artery is known as a thrombus. A blood clot that breaks off and travels through the bloodstream until it gets stuck in a smaller blood vessel and blocks the blood supply is known as an embolus.

How do they occur?

Blood clots can form due to abnormal levels of blood clotting proteins, or because of scars or plaque inside blood vessels. Some conditions make it more likely that you will develop blood clots:

  • cancer
  • diabetes
  • hardening of the arteries
  • heart valve disease or heart failure
  • immune system disorders such as lupus or rheumatoid arthritis
  • inflammatory bowel disease
  • family history of blood clots
  • pregnancy

Blood clots can result from other problems such as:

  • being bedridden after surgery
  • accidents
  • long-term immobility
  • use of birth control pills or estrogen replacement therapy
  • high dose corticosteroid therapy
  • catheters

Smokers, people who do not exercise, and obese people have a higher risk for developing blood clots in blood vessels.

What are the symptoms?

About half of people with blood clots have no symptoms until a clot blocks a major vein. When clots block blood flow, symptoms may include:

  • swelling, redness, or warmth in the calf, ankle, foot, or thigh
  • pain in the leg (usually the calf)
  • chest pain
  • shortness of breath
  • seizures or sudden weakness
  • severe abdominal pain with vomiting or diarrhea
  • bluish color of the skin on the leg or toes

How are they diagnosed?

Your healthcare provider will ask about your medical history and your symptoms. Your provider will examine you, especially any abnormal areas, such as a swollen leg. Other tests may be done to confirm the diagnosis, such as:

  • Duplex ultrasound uses both sound echo and Doppler echo signals to make pictures. The ultrasound bounces sound waves off the deep veins in an arm or leg. These echo pictures help locate any blockages. Doppler ultrasound signals measure how fast the blood flows through the veins.
  • Contrast venography usually shows any blockages in your veins. During venography a special dye is injected into a vein while X-ray pictures are taken.
  • Angiography uses special X-rays to show the walls of the arteries and any blockage. A special dye that shows up in an X-ray is injected into a blood vessel through a thin tube called a catheter. As the dye flows in the blood vessel, a series of X-rays are taken.
  • MRI (magnetic resonance imaging) uses magnetism, radio waves, and a computer to make pictures that can show plugged blood vessels.
  • CT (computed tomography) scan, in which X-rays are taken at different angles and then combined by a computer.

How are they treated?

If the blood clot is in a vein, your healthcare provider may recommend that you:

  • Put warm, moist compresses on the inflamed area (be careful to avoid burns).
  • Rest and elevate your arm or leg while you have pain and swelling.
  • Ask your healthcare provider if you need to limit any of your activities.
  • Take an anti-inflammatory drug, such as aspirin or ibuprofen.
  • Nonsteroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen and aspirin, may cause stomach bleeding and other problems. These risks increase with age. Read the label and take as directed. Unless recommended by your healthcare provider, do not take for more than 10 days for any reason.
  • Check with your healthcare provider before you give any medicine that contains aspirin or salicylates to a child or teen. This includes medicines like baby aspirin, some cold medicines, and Pepto Bismol. Children and teens who take aspirin are at risk for a serious illness called Reye’s syndrome.

If you have blood clots in an artery, or deep in the veins, you may need to take a blood thinner. If you have a condition that puts you at high risk for blood clots you may need to take medicine for the rest of your life.

A catheter (small tube) inserted into your blood vessel may be used to remove a blood clot.

You may need surgery to remove the clot. If you keep having problems, you may have surgery to put a small plastic filter in the large abdominal vein that returns blood to the heart. The filter can trap blood clots and prevent them from reaching your lungs.

How can they be prevented?

  • Avoid sitting for long periods of time. When you are traveling–for example, on a long airplane trip–move your feet and legs often. Go for short walks if possible. You should not sit for more than 2 hours when traveling.
  • Avoid crossing your legs and ankles when you sit.
  • Get regular exercise, according to your healthcare provider’s advice.
  • Cut back on fats and cholesterol in your diet.
  • Maintain a healthy body weight.
  • Elevate your legs when you are in bed or sitting down.
  • Stop smoking. Smoking increases the risk for blood clots.
  • Talk with your healthcare provider about all supplements and nonprescription medicines that you take. Some herbs, such as garlic and ginseng, may increase your risk.
