What is the difference between an embolus and embolism?
Types
- Pulmonary embolism – A complication that arises when a piece of thrombus blocks the pulmonary artery or its branches
- Brain embolism – An obstruction in the supply of blood to part of the brain caused by debris (embolus) or a blood clot
- Retinal embolism – blocked arteries in the retina of an eye
What does embolus mean?
What Is an Embolus? An embolus is the term given to a substance that travels through blood vessels until it reaches a vessel that is too small and becomes stuck. An embolus can be comprised of many different substances, most often it is a piece of a blood clot that has broken off and traveled through the blood stream.
How does a blood clot in the lung kill you?
A pulmonary embolism is a blood clot that occurs in the lungs. It can damage part of the lung due to restricted blood flow, decrease oxygen levels in the blood, and affect other organs as well. Large or multiple blood clots can be fatal. The blockage can be life-threatening.
What can cause an embolism?
- Advanced maternal age. If you're 35 or older at the time of your child's birth, you might be at increased risk of amniotic fluid embolism.
- Placenta problems. ...
- Preeclampsia. ...
- Medically induced labor. ...
- Operative delivery. ...
- Polyhydramnios. ...
What is an example of an embolus?
Examples of Embolic Disease A pulmonary embolus is most often caused by deep vein thrombosis (blood clot formation) in the legs. A cerebral embolus is an embolus that lodges in an artery supplying the brain, producing a stroke. A common cause of cerebral emboli is atrial fibrillation.
What does embolism mean?
Emboli: Something that travels through the bloodstream, lodges in a blood vessel and blocks it. Examples of emboli are a detached blood clot, a clump of bacteria, and foreign material such as air.
Where is the embolus?
An embolus is a particle that moves about in our blood vessels, either in the veins or arteries. Most emboli are composed of clotted blood cells. A blood clot is called a thrombus and a moving blood clot is called a thromboembolus.
What is the difference between thrombus and embolus?
A thrombus is a blood clot that forms in a vein. An embolus is anything that moves through the blood vessels until it reaches a vessel that is too small to let it pass. When this happens, the blood flow is stopped by the embolus. An embolus is often a small piece of a blood clot that breaks off (thromboembolus).
What causes embolism?
An embolism is a blocked artery caused by a foreign body, such as a blood clot or an air bubble. The body's tissues and organs need oxygen, which is transported around the body in the bloodstream.
Is an embolism a stroke?
Embolic strokes are usually caused by a blood clot that forms elsewhere in the body (embolus) and travels through the bloodstream to the brain. Embolic strokes often result from heart disease or heart surgery and occur rapidly and without any warning signs.
Can embolism be treated?
How Pulmonary Embolism Is Treated. Treatment is aimed at keeping the blood clot from getting bigger and preventing new clots from forming. Prompt treatment is essential to prevent serious complications or death. Blood thinners or anticoagulants are the most common treatment for a blood clot in the lung.
What is the difference between a blood clot and an embolism?
Thrombosis occurs when a thrombus, or blood clot, develops in a blood vessel and reduces the flow of blood through the vessel. Embolism occurs when a piece of a blood clot, foreign object, or other bodily substance becomes stuck in a blood vessel and largely obstructs the flow of blood.
Can embolism be cured?
Pulmonary embolism is serious but very treatable. Quick treatment greatly reduces the chance of death. Symptoms may include: Sudden shortness of breath -- whether you've been active or at rest.
Is an embolus a clot?
An "embolus" is a blood clot or a piece of plaque that acts like a clot. The word "emboli" means there is more than one clot or piece of plaque. When the clot travels from the site where it formed to another location in the body, it is called an embolism. An arterial embolism may be caused by one or more clots.
Is embolism same as aneurysm?
Is It an Embolism or an Aneurysm? Both embolisms and aneurysms have similar-sounding names and can affect blood flow in the brain, but that's where the similarities end. An embolism blocks blood flow because of a clot, while an aneurysm is when an artery breaks or twists, causing bleeding.
Is DVT same as embolism?
A deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, usually in the lower leg, thigh, or pelvis. A pulmonary embolism (PE) occurs when a clot breaks loose and travels through the bloodstream to the lungs.
What happens when you have an embolism?
A pulmonary embolism (PE) can cause a lack of blood flow that leads to lung tissue damage. It can cause low blood oxygen levels that can damage other organs in the body, too. A PE, particularly a large PE or many clots, can quickly cause serious life-threatening problems and, even death.

What is the most common type of embolism?
Here are some of the most common:Pulmonary embolism: Typically caused by DVT, a pulmonary embolism takes place when an embolus forms in the leg before traveling to the lungs. ... Air embolism: Common in divers, air embolisms involve tiny pockets of air entering the bloodstream and forming bubbles which block blood flow.More items...•
What is the medical term for an embolus?
Emboli, (the plural form of embolus), come in different types; the medical condition resulting from an embolus is called an embolism.
What Is an Embolus?
An embolus is the term given to a substance that travels through blood vessels until it reaches a vessel that is too small and becomes stuck. An embolus can be comprised of many different substances, most often it is a piece of a blood clot that has broken off and traveled through the blood stream. It can also be fat, tissue, a product of infection, or an air bubble, since air bubbles are not supposed to be in the blood stream. An embolus can also be a foreign substance, such as a piece of a medical device or a piece of cotton. You might be thinking, how does a person get cotton in the blood stream? Well, take intravenous drug users for example. Before they inject heroin into their veins using a syringe, they filter the heroin through a piece of cotton. Some of the cotton fibers get sucked up into the syringe and accidentally get shot though the blood stream along with the heroin. Yuck!
How to tell if you have an embolus in your leg?
Having an embolus in the leg may cause a feeling of pain, a charley horse-type feeling, or a cramping feeling in the thigh, in the calf, or behind the knee. You may see some changes in color around the area, like redness or bruising, and even swelling may also be present. Serious symptoms of emboli in the heart, lungs, or brain include chest pain, difficult breathing, numbness, weakness, difficulty speaking, or severe headache. These more serious symptoms require immediate medical attention to prevent irreversible tissue damage from lack of oxygen or even death.
How to treat embolism?
Treatment is aimed at first recognizing that an embolism is blocking blood flow by use of ultrasound, x-ray, CAT scan (computerized axial tomography), or MRI (magnetic resonance imaging). Treatment is then aimed at restoring blood flow to the surrounding tissues that have been compromised by the lack of blood flow from the embolus and at providing comfort to the patient. A patient may require a clot-busting medication if the embolus includes clotted blood cells to break apart the clot. In cases of a blocked heart vessel, a stent may need to be surgically implanted. A stent is a coil-shaped device that is surgically implanted under anesthesia and placed inside a blocked blood vessel to keep it held open. Bypass surgery is sometimes performed, where other healthy blood vessels are harvested from a patient and are surgically implanted around the blocked vessels to restore blood flow. Patients may require daily doses of anticoagulants, or blood thinners, to prevent more emboli from forming in other places in their body. Other treatments are staying active and using supportive, elastic stockings to improve circulation. In some instances, the emboli cannot be treated or do not go away and the patient must be treated with comfort measures such as oxygen therapy to help them breathe and pain medication to manage their symptoms.
How does an embolism affect the brain?
An embolism that blocks a vessel in the brain can cause a stroke by preventing oxygen from reaching the brain tissue. This alters the body's functions which the affected portion of the brain would typically control.
