Under what circumstances would surgery be used for treatment of pulmonary embolism?
A pulmonary embolism occurs when a blood clot blocks one of the arteries in the lungs. A pulmonary embolism can happen after surgery if a blood clot forms inside one of the veins in the body and travels to the lungs. Show Although most people recover with treatment, a pulmonary embolism can sometimes be fatal. In this article, we look at how often pulmonary embolisms occur after surgery and when they can develop. We also discuss the symptoms, diagnosis, treatment, and prevention. After surgery, there is a risk that a blood clot may form in the veins. This risk is due to the period of physical inactivity during and after the procedure. Long periods of physical inactivity can mean that the blood does not circulate as well as it should. When blood pools, clots can form. The risk is particularly high following major surgery on the abdomen, pelvis, or legs. The risk of pulmonary embolism varies among individuals, depending in part on their other risk factors. In general, pulmonary embolism is the third most common cause of cardiovascular death worldwide, after stroke and heart attack. According to the American Lung Association, pulmonary embolism affects about 1 in 1,000 people in the United States every year. However, with quick treatment, most people recover. Experts generally consider the risk of developing a pulmonary embolism after surgery to be highest during the first 5 weeks after surgery. A 2019 study found that the risk was highest between 1 and 6 weeks after surgery. The study included more than 60,000 middle-aged adults from a French patient database. For several types of surgery, the risk of pulmonary embolism remained elevated for 12 weeks in total. After 18 weeks, the researchers found no significant risk. The symptoms of a pulmonary embolism can vary depending on the size of the clot. They can include:
Most people will experience some symptoms, but not everyone does initially. Pulmonary embolisms can be life threatening. If someone experiences any of the symptoms of a pulmonary embolism, they should contact a doctor right away. Doctors use three methods to diagnose a pulmonary embolism: medical history, a physical exam, and medical imaging or blood tests. Physical examDuring a physical exam, a doctor will look for any swollen or discolored areas on the arms or legs. They will listen to the heart and lungs and take a blood pressure reading. Blood testsDoctors may order a D-dimer blood test. D-dimer is a substance present in the bloodstream when a blood clot dissolves. High levels can indicate a blood clot. Medical imagingImaging tests that a doctor may recommend include:
Doctors may use an MRI of the legs or lungs for those who are pregnant or cannot tolerate the contrast dyes that some imaging techniques require. Once a person receives a diagnosis of pulmonary embolism, they should start treatment straight away. First-line treatments do not dissolve the existing clot. Instead, doctors monitor the clot to make sure that the body is breaking it down on its own and prescribe medications to prevent new clots from forming. People may need to take these medications for long periods, usually for at least 3 months. Treatment may involve:
Bed rest after surgery increases the risk of a pulmonary embolism, but there are also other risk factors. These include:
Although rare, a pulmonary embolism can also develop if a blockage develops from air bubbles, tissue from a tumor, or fat from the marrow of a broken arm or leg. After major surgery, it can be difficult to reduce the risk of pulmonary embolism, as people are often unable to move around. However, until a person recovers, there are ways to reduce the risk. These include:
If someone is at high risk for a pulmonary embolism, a doctor may suggest taking anticoagulants following surgery as a preventive measure. Alternatively, they may recommend inserting a filter into the inferior vena cava vein, which runs along the spinal column. This filter catches blood clots before they reach the lungs. Before or after surgery, people can also reduce the risk of pulmonary embolism by making dietary and lifestyle changes, such as:
A pulmonary embolism occurs when a blood clot blocks an artery in the lungs. The risk of pulmonary embolism after surgery is highest for the first 1–6 weeks, particularly if a person cannot move around. Takin anticoagulants, using compression devices, and gradually increasing movement can reduce the risk. Anyone who is concerned about the risk of pulmonary embolism after surgery can speak with a doctor. When is surgery needed for pulmonary embolism?Rarely used, this is surgery done to remove a PE. It is generally done only in severe cases when your PE is very large, you can't get anticoagulation and/or thrombolytic therapy due to other medical problems or you haven't responded well to those treatments, or your condition is unstable.
Can you surgically remove a pulmonary embolism?Surgical and other procedures
If you have a very large, life-threatening clot in your lung, your doctor may suggest removing it via a thin, flexible tube (catheter) threaded through your blood vessels.
What is the most common treatment for pulmonary embolism?Taking anticoagulant drugs. The main treatment for pulmonary embolism is called an anticoagulant. This is a drug that causes chemical changes in your blood to stop it clotting easily. This drug will stop the clot getting larger while your body slowly absorbs it.
Which is the treatment of choice for pulmonary embolism?Blood thinners or anticoagulants are the most common treatment for a blood clot in the lung. While hospitalized an injection is used, but this will be transitioned into a pill regimen when the patient is sent home.
