These types of blood clots do not usually travel to the lungs unless they move from the superficial system into the deep venous system first. A DVT usually forms in one leg or one arm. Not everyone with a DVT will have symptoms, but symptoms can include:. Some people do not know they have a DVT until the clot moves from their leg or arm and travels to their lung.
Deep Vein Thrombosis (DVT)
It is important to call your doctor right away or go to the emergency room if you have symptoms of a pulmonary embolism or DVT. Cleveland Clinic is a non-profit academic medical center.

A clot might be visible in the image. Sometimes a series of ultrasounds are done over several days to determine whether a blood clot is growing or to check for a new one.

Compression stockings, also called support stockings, compress your legs, promoting circulation. A stocking butler may help you put on the stockings. Deep vein thrombosis DVT treatment is aimed at preventing the clot from getting bigger and preventing it from breaking loose and causing a pulmonary embolism. Then the goal becomes reducing your chances of deep vein thrombosis happening again. Blood thinners. Deep vein thrombosis is most commonly treated with anticoagulants, also called blood thinners.
These drugs, which can be injected or taken as pills, decrease your blood's ability to clot. They don't break up existing blood clots, but they can prevent clots from getting bigger and reduce your risk of developing more clots. The injectable medications can be given as a shot under the skin or by injection into your arm vein intravenous.
Heparin is typically given intravenously. Other similar blood thinners, such as enoxaparin Lovenox , dalteparin Fragmin or fondaparinux Arixtra , are injected under the skin. You might receive an injectable blood thinner for a few days, after which pills such as warfarin Coumadin, Jantoven or dabigatran Pradaxa are started. Once warfarin has thinned your blood, the injectable blood thinners are stopped. Other blood thinners can be given in pill form without the need for an injectable blood thinner.
These include rivaroxaban Xarelto , apixaban Eliquis or edoxaban Savaysa. You might need to take blood thinner pills for three months or longer. It's important to take them exactly as your doctor instructs because taking too much or too little can cause serious side effects. If a person experiences any of the following, they should see a doctor immediately:.
A doctor will start by asking the person about their symptoms, and they will do a physical examination. They may then order some imaging tests. A mathematical model can help doctors assess a person's risk of DVT and PE using a range of chemical signs in the blood. It is often the first test a doctor will perform when trying to diagnose DVT. A D-dimer test is a blood test that can determine if there might be any excess blood clotting in the body. Doctors will usually carry this out after a mathematical model. If it is negative and you have a low risk for blood clots, the chance of having a DVT or PE is very low.
No further testing would be necessary after a negative D-dimer result. However, a positive test does not necessarily indicate a serious problem. This could refer to something as simple as blood clotting in a healing skin wound or bruise. A VQ scan of the lungs can identify how well blood and oxygen are moving in the lungs.
It involves the administration of a small amount of a radioactive substance. However, if an individual requires further testing after a D-dimer test, doctors should use a VQ scan instead of a CT scan.
The person's exposure to radiation is lower. A duplex ultrasound examination can detect blood clots in veins or other reasons for the vascular problem. A spiral chest CT scan can check for blood clots in the arteries of the lungs, commonly done with an intravenous injection of contrast to better see the pulmonary arteries. An MRI can evaluate the veins in the pelvis or both legs at the same time. Venography involves injecting dye into a vein of an extremity and taking an x-ray to look for any blockages.
Blood tests can also find out if a person has a clotting disorder, of which several types exist.
However, these tests are very expensive, and the results can take several days. A person with DVT will usually need anticoagulants, or blood thinners, such as warfarin Coumadin. People who need to take anticoagulants should seek treatment from a specialized anticoagulant management service rather than their family doctor or a primary care physician.
However, anticoagulants do not break up existing blood clots.
Deep Vein Thrombosis (DVT, Blood Clot in the Legs)
They can only interrupt the clotting process so that the body can break down the clots through its normal mechanisms. Most people will need to use anticoagulant medication for at least 3 months, but each person is different. The doctor inserts this filter is into a large vein in the abdomen called the inferior vena cava. There, it can catch blood clots before they can cause PE. However, the filter does not stop new blood clots from forming.
Sometimes clots can pass around the filter through smaller veins or form on the filter, break off, and still reach the lungs. The IVC filter may also be used for some patients in addition to anticoagulant medication therapy.
This breaks down the blood clot, but it can be dangerous, as it may lead to bleeding in other parts of the body, such as the brain and the gastrointestinal tract. In rare cases, a surgeon may need to remove the blood clot from the lungs in a procedure known as an embolectomy. This is a risky procedure. The doctor usually would only use it as a last resort in a very severe case. When traveling on an airplane, people can walk up and down the aisle every half an hour. People with a family or personal history of blood clots should pay attention to signs and symptoms that could indicate DVT or PE.
It is important to keep moving and avoid being still for long periods of time, to lessen the chances of DVT and PE occurring. People should try to make well-balanced and healthy dietary choices, especially if they have a risk of DVT. This includes healthy portion sizes and a good balance of lean meats or fish, vegetables, fruits, and whole grains. This can help you to maintain a healthier weight and provide energy for you to be more physically active.
Combined with an active lifestyle, a healthy diet can help you to avoid becoming sedentary, and this will lower your risk for DVT and subsequent PE.
