Can you feel pulmonary embolism

As it moves through the veins back to the heart, blood flow slows. Sometimes this slower blood flow may lead to clot formation. Blood clotting is a normal process to prevent bleeding. The body makes blood clots and then breaks them down.

Under certain circumstances, the body may be unable to break down a clot. This may result in a serious health problem. When blood clots in a vein, it may be due to the slowed blood flow, an abnormality in clot forming, or from an injury to the blood vessel wall. Blood clots can form in arteries and veins. Clots formed in veins are called venous clots. Veins of the legs can be superficial veins close to the surface of the skin or deep veins located near the bone and surrounded by muscle.

Venous clots most often happen in the deep veins of the legs. This is called deep vein thrombosis DVT. Once a clot has formed in the deep veins of the leg, there is a potential for part of the clot to break off and travel through the blood to another area of the body, often the lung.

DVT is the most common cause of a pulmonary embolism. Other less frequent sources of pulmonary embolism are a fat embolus often linked to the breaking of a large bone , amniotic fluid embolus, air bubbles, and a deep vein thrombosis in the upper body.

Clots may also form on the end of an indwelling intravenous IV catheter, break off, and travel to the lungs. Situations in which mobility is limited, such as extended bed rest, flying or riding long distances, or paralysis. Certain medical conditions, such as heart failure, chronic obstructive pulmonary disease COPD , high blood pressure, stroke, and inflammatory bowel disease.

The following are the most common symptoms for pulmonary embolism PE. However, each person may experience symptoms differently:. If your healthcare provider thinks you have a PE, he or she will check your legs for signs of deep vein thrombosis. The symptoms of a PE may look like other medical conditions or problems. Always talk with a healthcare provider for a diagnosis.

Pulmonary embolism PE is often difficult to diagnose because the symptoms of PE are a lot like those of many other conditions and diseases.

Along with a complete medical history and physical exam, tests used to look for a PE may include:. Chest X-ray. This imaging test is used to assess the lungs and heart. Chest X-rays show information about the size, shape, contour, and anatomic location of the heart, lungs, bronchi large breathing tubes , aorta and pulmonary arteries, and mediastinum area in the middle of the chest separating the lungs. For this nuclear radiology test, a small amount of a radioactive substance is used to help examine the lungs.

A ventilation scan evaluates ventilation, or the movement of air into and out of the bronchi and bronchioles. A perfusion scan evaluates blood flow within the lungs. Pulmonary angiogram. This X-ray image of the blood vessels is used to evaluate various conditions, such as aneurysm bulging of a blood vessel , stenosis narrowing of a blood vessel , or blockages.

A dye contrast is injected through a thin flexible tube placed in an artery. This dye makes the blood vessels show up on X-ray. This is an imaging test that uses X-rays and a computer to make detailed images of the body.

A CT scan shows details of the bones, muscles, fat, and organs. CT with contrast enhances the image of the blood vessels in the lungs. Contrast is a dye-like substance injected into a vein that causes the organ or tissue under study to show up more clearly on the scan. Some important risk factors are immobility, other serious illnesses, and major surgery especially gynaecological surgery, and operations on the pelvis and legs.

The risk of developing a DVT or PE in hospital can be greatly reduced by getting the patient up and walking as soon as possible. Half of all people with a PE develop it when they are a hospital inpatient. Give yourself a check-up with a general blood profile, now available in Patient Access. The symptoms will depend on how large or small the clot is, and on how well the person's lungs can cope with the clot.

People who are frail or have existing illness are likely to have worse symptoms than someone who is fit and well. Symptoms often start suddenly. There may be symptoms of a DVT, such as pain at the back of the calf in the leg, tenderness of the calf muscles or swelling of a leg or foot. The calf may also be warm and red. A massive PE is so called not due to the actual size of the blood clot embolus but due to the size of its effect.

A PE is high-risk if it causes serious problems such as a collapse or low blood pressure. Massive PEs are, by definition, high-risk.

The diagnosis is often suspected on the basis of symptoms and your medical history. For example, someone who has had major surgery, been immobile in hospital and then gets sudden breathlessness, is likely to have a PE.

If you are not pregnant, your healthcare professional may use the Wells' score to decide whether admission to hospital is necessary. This assesses your risk of having a PE by looking at whether you have:.

If your score is high enough, you will need to go to hospital. Various tests may be used to help confirm the diagnosis. These may include one or more of the following:.

A type of ultrasound called a duplex Doppler is used to show blood flow in the leg veins, and any blockage to blood flow. Ultrasound is useful because it is an easy, non-invasive test and may show up a DVT. If a DVT is found, then a PE can be assumed to be the cause of the other symptoms such as breathlessness or chest pain.

Treatment with anticoagulant medication - see below can be started immediately for both the DVT and the suspected PE. The treatment is generally the same for both. Further tests may be unnecessary in this situation. However, if the ultrasound is negative, a DVT or PE is not ruled out, because some clots don't show up on ultrasound. Further tests will be needed.

Lower limb compression venous ultrasound may be useful for pregnant women in whom irradiation from other imaging may be harmful. This detects fragments of breakdown products of a blood clot.

The higher the level, the more likely you have a blood clot in a vein. Unfortunately, the test can be positive in a number of other situations, such as if you have had recent surgery or if you are pregnant. The test may, however, indicate how likely it is that you have a blood clot the clot can be either a DVT or a PE.

This can help decide if further tests are needed. A negative D-dimer result when you are at low risk of VTE means the chance of having a thrombus is extremely low. However, if your VTE risk is high, then a D-dimer test cannot rule out the possibility of a thrombus and you will need other tests.

An echocardiogram is useful for people who may have a massive PE, as it can show the effect on the heart. If there is a massive PE then this puts strain on the right-hand side of the heart. It can be done at the bedside. These are specialised scans which look at the circulation in the lung.

They are useful, because they can show quite accurately whether or not a PE is present. See the separate leaflet called Radionuclide Isotope Scan. The CTPA scan is a type of CT scan looking at the lung arteries - the full name is computerised tomographic pulmonary angiography scan.

Other tests on the heart, lung and blood are usually done. These may help with the diagnosis or may show up other conditions:. This section deals with PE due to a blood clot, not with the rare causes listed above. The main treatments are:. If no concerning features are present then patients can be assessed in hospital and blood samples sent off. If there is still a possibility of PE you may be started on low molecular weight heparin LMWH injections and sent home to then return and have further scans the next day.

You will then return for the result where either treatment will stop or further treatment and advice will be given. Anticoagulation is often called thinning the blood. However, it does not actually thin the blood. It alters certain chemicals in the blood to stop clots forming so easily. It doesn't dissolve the clot either as some people incorrectly think.

Anticoagulation prevents a PE from getting larger and prevents any new clots from forming. The body's own healing mechanisms can then get to work to break up the clot. Anticoagulation treatment is usually started immediately as soon as a PE is suspected in order to prevent the clot worsening, while waiting for test results. Anticoagulation medication comes in two forms: injections and tablets or syrup for those who cannot swallow tablets.
