Deep Venous Thrombosis
WHAT YOU NEED TO KNOW:
Deep venous thrombosis (DVT) is a blood clot that forms in a deep vein of the body. The deep veins in the legs, thighs, and hips are the most common sites for DVT. DVT can also occur in a deep vein within your arms. The clot prevents the normal flow of blood in the vein. The blood backs up and causes pain and swelling. The DVT can break into smaller pieces and travel to your lungs and cause a blockage called a pulmonary embolism. A pulmonary embolism can become life-threatening.
Call 911 for any of the following:
- You feel lightheaded, short of breath, and have chest pain.
- You cough up blood.
Return to the emergency department if:
- Your symptoms get worse.
- You develop new DVT symptoms in another leg or arm.
Contact your healthcare provider if:
- You have questions or concerns about your conditions or care.
- Blood thinners help prevent the DVT from getting bigger and prevent new clots from forming. Examples of blood thinners include heparin, rivaroxaban, apixiban, and warfarin. The following are general safety guidelines to follow while you are taking a blood thinner:
- Watch for bleeding and bruising. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
- Tell your dentist and other healthcare providers that you take a blood thinner. Wear a bracelet or necklace that says you take this medicine.
- Do not start or stop any medicines unless your healthcare provider tells you to. Many medicines cannot be used with blood thinners.
- Tell your healthcare provider right away if you forget to take the blood thinner , or if you take too much.
- Warfarin is a blood thinner that you may need to take. The following are additional things you should be aware of if you take warfarin:
- Foods and medicines can affect the amount of warfarin in your blood. Do not make major changes to your diet. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables and certain other foods. Ask for more information about what to eat or not to eat.
- You will need to see your healthcare provider for follow-up visits. You will need regular blood tests to decide how much warfarin you need.
- Take your medicine as directed. Call your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
Manage your DVT:
- Pressure stockings are tight and put pressure on your legs. This improves blood flow and helps prevent clots.
- Elevate your legs above the level of your heart as often as you can. This will help decrease swelling and pain. Prop your legs on pillows or blankets to keep them elevated comfortably.
- Exercise , such as walking, will help increase your blood flow. Talk to your healthcare provider about the best exercise plan for you.
- Change body positions often. If you travel by car or work at a desk, move and stretch in your seat several times each hour. In an airplane, get up and walk every hour. If you are bedridden, ask for help to change your position every 1 to 2 hours.
- Do not smoke. Nicotine can damage blood vessels and make it more difficult to manage your DVT. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your healthcare provider for information if you currently smoke and need help quitting.
