A pulmonary embolism (PE) is a blood clot that develops in a blood vessel, often in the leg, and travels to a lung artery, blocking blood flow. This blockage can cause problems with the heart and breathing and may even lead to sudden death. Given the serious nature of pulmonary embolisms, it is important to be aware of the symptoms and seek immediate medical attention. While hospitalization is not always necessary, it is crucial to consult a doctor as soon as possible to prevent complications and ensure rapid treatment.

Pulmonary embolism (PE) causes
A pulmonary embolism (PE) is a blood clot that develops in a blood vessel in the body and travels to the lungs, blocking blood flow. PE is a serious and potentially fatal condition that can cause heart and lung problems and breathing difficulties. It is a medical emergency, and those who suspect they are experiencing symptoms should seek immediate medical attention.
PE is often the result of a deep vein thrombosis (DVT), where a blood clot forms in the deep veins of the leg and then breaks off and travels through the blood to the lungs. This is known as venous thromboembolism (VTE). DVT is the most common cause of PE, but it can also be caused by other factors, such as a fat embolus, amniotic fluid embolus, air bubbles, or a thrombus in the upper body. Certain situations, such as limited mobility, extended bed rest, long-distance travel, or paralysis, can increase the risk of developing PE. Additionally, certain medical conditions like heart failure, chronic obstructive pulmonary disease (COPD), high blood pressure, stroke, and inflammatory bowel disease are also risk factors.
The formation of blood clots, or thrombi, in the veins can be influenced by slower blood flow as it moves through the veins back to the heart. This slower flow may lead to clot formation, which can then break off and travel to the lungs, causing PE.
PE is a life-threatening condition due to the obstruction of the pulmonary arteries, which supply blood to the lungs. When a blood clot enters the pulmonary circulation, it can lead to multiple emboli, with larger emboli tending to obstruct the main pulmonary artery and smaller emboli blocking the peripheral arteries. This blockage can result in serious cardiovascular consequences and pulmonary infarction, which is the death of lung tissue due to a lack of blood supply.
The timely diagnosis of PE is crucial due to its high associated mortality and morbidity rates. While early treatment can significantly improve outcomes, diagnosing PE can be challenging due to nonspecific symptoms that overlap with other cardiovascular and respiratory conditions. However, with advancements in diagnostic tools and treatment options, case-fatality rates for PE have decreased over time.

PE symptoms
A pulmonary embolism (PE) is a blood clot that develops in a blood vessel in the body, often in the leg, and travels to a lung artery, blocking blood flow. This blockage of a blood vessel by an embolus (a clot that has travelled from one area of the body to another via the blood) can cause serious complications and even be fatal.
The symptoms of PE include:
- Shortness of breath, which may come on suddenly
- Chest pain, which may worsen with deep breaths, coughing, eating, or bending
- Coughing, which may include coughing up blood
- A rapid heartbeat or irregular heart rhythm
- Clammy or discoloured skin
If you are experiencing any of these symptoms, it is important to seek medical attention immediately, as PE can be a medical emergency.

PE diagnosis
Pulmonary embolism (PE) is a serious condition that occurs when a blood clot blocks one or more pulmonary arteries in the lungs. Due to its potentially fatal consequences, it is important to diagnose PE accurately and promptly. Here is an overview of the diagnostic process for PE:
Clinical Assessment
The first step in diagnosing PE is a thorough clinical evaluation by a healthcare provider. This includes obtaining a detailed medical history, including any risk factors for PE, such as deep vein thrombosis (DVT), recent surgery, or limited mobility. A physical examination will also be performed, focusing on vital signs and assessing for symptoms suggestive of PE or other differential diagnoses.
Blood Tests
Blood tests, such as the D-dimer test, play a crucial role in the diagnostic workup for PE. D-dimer is a protein fragment released when a blood clot dissolves. Elevated D-dimer levels in the blood can indicate the presence of a blood clot, prompting further imaging tests to confirm PE.
Imaging Tests
Several imaging modalities are available to diagnose PE:
- Chest X-ray: While a chest X-ray cannot directly visualize blood clots, it helps rule out other conditions with similar symptoms, such as pneumonia or an enlarged heart.
- Computed Tomographic Pulmonary Angiography (CTPA): This CT scan technique uses contrast dye to visualize the pulmonary arteries and detect any blockages caused by blood clots.
- Ventilation-Perfusion Scan (VQ Scan): This test evaluates both airflow and blood flow in the lungs. A radioactive tracer and a radioactive gas are used to identify areas of reduced blood flow, which may indicate the presence of a clot.
- Magnetic Resonance Imaging (MRI): MRI scans use magnetic fields and radio waves to create detailed images of the body, including the blood vessels in the lungs, to detect any abnormalities.
- Duplex Ultrasound: This test assesses blood flow and the structure of blood vessels in the legs, as deep vein clots in the legs can dislodge and travel to the lungs.
- Echocardiogram: While not primarily used for PE diagnosis, an echocardiogram can reveal strain on the right side of the heart caused by a large PE, as well as heart problems that may mimic PE symptoms.
Invasive Tests
In rare cases, a pulmonary angiogram may be performed. This invasive test involves injecting a contrast dye directly into the pulmonary arteries to visualize blood flow and detect any blockages caused by clots.
In summary, diagnosing PE involves a comprehensive clinical assessment, blood tests, and various imaging modalities. Prompt diagnosis is crucial to initiate timely treatment and prevent potentially life-threatening complications.

PE treatment
Pulmonary embolism (PE) is a serious and potentially fatal condition that occurs when a blood clot blocks one or more pulmonary arteries in the lungs. It is a medical emergency that requires immediate medical attention to prevent serious complications and death.
The treatment for PE focuses on preventing the clot from growing larger and stopping new clots from forming. The most common treatment is the use of blood thinners or anticoagulants, which can be administered through injections or pills. These medications do not dissolve blood clots but help to stabilise the patient and prevent further complications. In most cases, the body will eventually dissolve the clot on its own. However, if this does not occur, more aggressive treatments may be necessary.
For life-threatening situations, clot dissolvers called thrombolytics can be used. This medication can cause sudden and severe bleeding, so it is reserved for critical cases. When blood thinners are ineffective or unsuitable, a procedure called inferior vena cava filter placement may be recommended. This involves inserting a filter into the inferior vena cava, the body's main vein, to prevent clots from reaching the lungs. The filter can often be removed once the risk has passed.
In rare and severe cases, a surgical procedure called embolectomy or thrombectomy may be necessary. This involves using a thin, flexible tube called a catheter to remove the clot through the blood vessels.
After initial treatment for PE, long-term management is crucial to prevent recurrence. Patients may need to take blood thinners or anticoagulants for at least three months or even indefinitely. It is important to work closely with healthcare professionals to determine the best treatment plan and duration of therapy based on individual risk factors.

PE prevention
A pulmonary embolism (PE) is a serious blockage in the arteries of the lungs. It is usually caused by blood clots that develop in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can break loose and travel through the bloodstream to the lungs, leading to pulmonary embolism. This starves the lung tissue of blood, making it difficult or impossible for the lungs to provide oxygen to the rest of the body.
Pulmonary embolism is a medical emergency and requires immediate treatment with medication, surgery, or both. The best way to prevent pulmonary embolism is to minimize the chance of developing blood clots and deep vein thrombosis. Here are some ways to prevent pulmonary embolism:
Preventing Blood Clots
- Maintain adequate hydration: Dehydration can increase the risk of blood clots. Drinking plenty of water is important, especially when you've been immobile for several hours. Make time for bathroom breaks and stretch your legs.
- Wear compression stockings: Compression stockings help keep blood from pooling in the legs. They are recommended for long trips to help prevent blood clots.
- Move around regularly: During long car or plane rides, find ways to move as much as possible. Avoid crossing your legs for long periods. If you're on a plane, lift your knees and rotate your ankles to promote blood flow while sitting, and stand up and walk when possible. If you're in a car, take regular breaks to stretch and move around.
- Avoid prolonged immobility: Situations with limited mobility, such as extended bed rest, long-distance travel, or paralysis, can increase the risk of blood clots. If you're on bed rest, try to move around or do leg exercises as soon as it's safe. During long journeys, do leg stretching exercises every 30 minutes.
- Lose weight: Being obese puts additional pressure on the veins in the legs, contributing to poor blood flow and the development of blood clots. Losing weight can lower blood pressure and increase blood flow.
Medical Interventions
- Anticoagulants: People at risk of developing blood clots may be prescribed anticoagulants, or blood-thinning medications, before and after surgery.
- Vena cava filter: For individuals who cannot take blood thinners, a vena cava filter can be inserted inside a large vein called the vena cava. This filter catches blood clots before they travel to the lungs, preventing pulmonary embolism. However, it does not stop new blood clots from forming.
- Hormonal medication alternatives: Hormone replacement therapy and oral contraceptives increase the risk of developing blood clots and pulmonary embolism, especially if coupled with smoking or being overweight. Discuss alternatives with your doctor.
- Regular check-ups: Regular medical check-ups are important to monitor the effectiveness of your medications in preventing blood clots and to ensure they are not causing bleeding.
Remember, pulmonary embolism is a serious condition that requires immediate medical attention. If you think you are experiencing symptoms, seek medical advice promptly to receive timely treatment and prevent complications.

Frequently asked questions
A blood clot in the lung is called a pulmonary embolism or PE. It occurs when a clot in another part of the body, often the leg or arm, moves to the lung. A pulmonary embolism restricts blood flow to the lungs, lowers oxygen levels, and increases blood pressure in the pulmonary arteries.
Symptoms of a pulmonary embolism can include shortness of breath, anxiety, depression, or post-traumatic stress disorder.
Yes, a pulmonary embolism is a medical emergency that requires immediate medical attention. Healthcare providers usually treat PEs in a hospital, where they can closely monitor the patient's condition. However, the length of hospitalization can vary depending on the severity of the clot, and some people may not need to stay overnight.
The main treatment for a pulmonary embolism is an anticoagulant or blood thinner, which helps prevent new clots from forming. In most cases, the body will break down the existing clot on its own. If this does not happen, more aggressive treatments such as thrombolytic therapy, surgery, or interventional procedures may be necessary.
The recovery time for a pulmonary embolism can vary from person to person. Many people recover in several months, but some may experience long-term symptoms or complications that delay recovery. During the recovery process, it is important to follow the doctor's recommendations and take any prescribed medications to prevent future clots.
