Blood Clots in Lung

symptoms of blood clot in lung

What is it? Your blood goes from your heart to your lungs through your pulmonary artery. In the lungs the blood is supplied with oxygen, then it returns to the heart, which pumps the oxygen-rich blood to the rest of your body.

When an embolism gets captured in one of the arteries that go from the heart to the lungs, it’s called a pulmonary embolism (PE). The clot obstructs the normal circulation of blood.

This blockage can trigger serious issues, like damage to your lungs and low oxygen levels in your blood. The lack of oxygen can damage other organs in your body, too. If the clot is big or the artery is clogged by numerous smaller sized embolisms, a pulmonary embolism can be deadly.

Main Causes of Having Blood Clots in Lung

Pulmonary embolisms typically move to the lungs from a deep vein in the legs. Physicians call this “deep vein apoplexy” (DVT). These embolisms develop when the blood can’t flow freely through the legs due to the fact that your body is still for a long period of time, state throughout a long flight or drive. It may also take place if you’re on bed rest after surgery or illness.

What Else Could Raise My Chances of PE?

The danger factors are the exact same as those for DVT. Medical professionals describe these as “Virchow’s triad.” They include:

  • Being immobile for a prolonged amount of time or having changes in normal blood flow. This typically occurs if you’ve been hospitalized or on bed rest for a long period of time. It might also take place during a long flight or vehicle flight.
  • Increased clotting potential of your blood. Medical professionals call this “hypercoagulability.” This might be caused by medications, like birth control pills. Smoking cigarettes, cancer, current surgery, or pregnancy can also put you at threat.
  • Damage to a capillary wall. Trauma to your lower leg can result in this.

In rare cases, an artery in the lung can be obstructed by something aside from a clot, like an air bubble or part of a growth. If you break a huge bone, in some cases fat from the bone marrow can come through the blood and cause obstruction.

In lethal cases of pulmonary embolism, your doctor might decide to give you drugs called thrombolytics to break up the clot. It might even require to be taken out or broken up with surgery, though this is unusual.

Symptoms of Pulmonary Embolism

When an artery in your lung gets blocked by a blood clot, you have a pulmonary embolism.

Symptoms can vary. What you experience will likely depend on the size of the clot and just how much of your lung it impacts. If you have lung or heart problem, that can contribute, too.

PE Is a Medical Emergency

Symptoms of PE tend to come on unexpectedly. Call 911 if you have any of the following:

  • Shortness of breath
  • Chest pain
  • Cough (it may be bloody, and there may be blood in the gunk you cough up).
  • Pain in your back.
  • A lot more sweating than usual.
  • A lightheaded sensation, or passing out.
  • Blue lips or nails.

Indication of Deep Vein Thrombosis

When a clot types in a deep vein in your legs, it’s called deep vein thrombosis (DVT). If it breaks off and takes a trip to your lung, it ends up being a PE.

See your doctor immediately if you have any of the symptoms of DVT. If it’s discovered early, medical professionals can stop it from ending up being a pulmonary embolism. Signs of DVT include:.

  • Swelling of a leg or arm.
  • Leg pain or inflammation when you’re standing or walking.
  • A swollen leg or arm that feels warmer than normal.
  • Red or blemished skin in the affected arm or leg.
  • Veins in your arm or leg that are bigger than normal.

How Do Doctors Diagnose a Pulmonary Embolism?

If you believe you have a pulmonary embolism (PE), you must get medical aid immediately.

Your doctor will likely begin with a physical examination. He’ll look carefully at your legs to see if they’re swollen, tender, discolored, or warm. These are signs that you may have a clot deep in among your veins.

Next, your medical professional may order a variety of tests, like a chest X-ray or ultrasound. You may likewise have blood tests. These can measure the amount of oxygen and co2 in your blood. They can also assist your doctor discover a compound called D dimer. This is a small protein fragment that’s present in the blood after a clot is broken down by the body.

Other tests your medical professional might purchase include:

  • Computed tomographic angiography (CTPA). This is a special type of X-ray test. It’s also the primary one doctors utilize to see if you have a PE. Your physician will inject dye (” contrast”) into your veins. He’ll be able to see the blood vessels in your lungs on the X-ray.
  • Ventilation/perfusion (V/Q) scan. This test is used if the CTPA isn’t readily available, or isn’t a good match for you. It uses a radioactive product to show which parts of your lungs are getting air circulation (ventilation) and blood flow (perfusion). If there’s low blood flow to a specific area, however the air flow is normal, a clot may exist.
  • Pulmonary angiography. This is the most precise test to spot PE. It may be utilized if other tests have not revealed clear outcomes. A professional inserts a long, thin tube (catheter) into a big vein in your groin and into the arteries within your lung. He then injects dye through the catheter. Pictures of the blood vessels inside the lung will turn up on an X-ray.
  • MRI. This might be a good choice if you’re pregnant or your medical professional is worried that other tests that utilize contrast might be damaging to you.
  • Echocardiogram. This is an ultrasound of the heart. It can’t identify a PE, but it does show if you have stress on your heart triggered by one.

What’s the Treatment for a Pulmonary Embolism?

A pulmonary embolism (PE) is an embolism in the lung. It’s serious and can be dangerous. However fortunately is that if it’s captured early, doctors can treat it. Here’s a take a look at a few of the most typical ways they tackle this condition.

Blood Thinners

Also called “anticoagulants,” these are the most typical treatment for a blood clot in the lung. They serve 2 key roles: First, they keep the clot from getting any larger. Second, they keep new embolisms from forming.

They do not dissolve blood clots. Your body typically does that by itself gradually.

The most commonly recommended blood thinners are warfarin (Coumadin, Jantoven) and heparin. Warfarin is a pill and can deal with and avoid clots. You get it through a shot or an IV. There are numerous other blood thinners in pill type, and your physician will help decide which agent would work best in your situation. Heparin can lower the opportunities of another clot forming. You get it through a shot or an IV.

Treatment can begin while you’re in the healthcare facility or even in the ER and you can be discharged the exact same day. How long you’ll remain and be treated depends on your condition.

Low-molecular-weight heparins are also extensively utilized. These can be self-injected at home. They include:

  • Dalteparin (Fragmin).
  • Enoxaparin (Lovenox).
  • Tinzaparin (Innohep).

Internal bleeding is the main adverse effects of blood thinners. It can take place if the medicine thins your blood excessive. Your medical professional may give you blood tests to keep an eye on that. However, even when at healing dosages, internal bleeding remains a risk.

In dangerous situations, physicians might use what are called thrombolytic drugs. These rapidly separate clots that trigger serious symptoms. However they can cause sudden bleeding and are just used after mindful consideration.


In carefully picked cases, his is another first aid your medical professional may use. He’ll insert a thin, flexible tube into a vein in your thigh or arm. He’ll advance to your lung, where he’ll eliminate the embolisms or use medicine to dissolve it.

Other Treatments

If you can’t take blood thinners, your doctor may use these choices to treat your PE:.

Inferior vena cava filter. The inferior vena cava is a big vein that brings blood from the lower body to the heart. Your doctor can put a filter in it to stop embolisms before they get to your lungs. It won’t stop embolisms from forming – just from getting to the lungs.

Compression stockings. Sometimes called “support hose pipe,” compression socks go up to your knee and keep pressure on your legs so blood doesn’t pool or clot. (Most embolisms that end up in the lung start in the leg.).

Surgery. Seldom, an operation might be needed to get rid of a clot from the lung.

Recovering From a Pulmonary Embolism

A pulmonary embolism (PE) is brought on by a blood clot that gets stuck in an artery in your lungs. That blockage can damage your lungs and harm other organs if they do not get enough oxygen. It’s a serious condition, and healing can take weeks or months.

When you’ve had one, your chances of another go up. But you can do some things to keep your blood flowing and prevent future embolisms. You’ll also wish to watch your legs for signs of a new members clot. Call your medical professional right away if you discover any of these:

  • Swelling.
  • Pain.
  • Tenderness.
  • Warmer-than-normal or red skin.

Diet and Medications

Drugs called anticoagulants are the first tools medical professionals grab if you’ve had a pulmonary embolism. They’re referred to as “blood thinners” because they make it harder for your blood to embolisms. They do not separate an embolism, but they keep it from growing as your body dissolves it.

When you take blood thinners, you’ll require to change what you consume. For example, foods rich in vitamin K, which helps your body kind embolism, might keep blood thinners from working like they should. That suggests you might require to consume fewer leafy green veggies and limit fish, liver, and some type of vegetable oil.

Ask your medical professional if it’s OKAY for you to consume alcohol while you take blood thinners.

You also ought to talk with your doctor about any other prescription or non-prescription medicines you take. Some common ones can affect how blood thinners work, too: These include:

  • Aspirin.
  • Cold medicines.
  • Pain medicines.
  • Sleeping tablets.
  • Antibiotics.

You can anticipate to take blood thinners for a minimum of 3 months and potentially a lot longer. Some people require to take them for life.


Most people can stroll and do light housework right now after a pulmonary embolism, but you may burn out quickly or feel short of breath.

Your doctor most likely will offer you particular workouts to do for a number of weeks or months to help improve your strength and breathing. Follow those recommendations, however don’t push yourself, especially if anything hurts or you discover any swelling.

Compression Stockings

A pulmonary embolism frequently starts in your legs, in one of the veins that brings blood to your heart and lungs. Making sure that blood flows freely can help avoid another blood clot.

One method to do that is with unique socks called compression stockings. These socks get tighter as they decrease toward your ankle, which helps your leg muscles move blood up your leg. Your physician will provide you a prescription for compression stockings that states how much pressure they need to apply.

Mental Health

This sort of severe, painful experience can leave you feeling unfortunate or afraid, specifically if your recovery puts new limitations on what you can do. If you feel distressed or depressed, talk with your physician about a referral to a counselor or support system in your area.

The Best Ways to Help Prevent a Blood Clots in Lung

When among the arteries that carries blood from your heart to your lungs gets obstructed, you have what physicians call a pulmonary embolism, or PE.

The majority of the time, this happens after an embolism kinds deep in a vein, typically in your leg. Physicians call this deep vein thrombosis, or DVT. If the clot breaks off and takes a trip to your lungs, it can block your blood circulation, triggering a PE.

The very best way to avoid a PE is to attempt to stop embolism from forming deep in your veins. This can be challenging if you’ve been on bed rest after a surgery or disease, or simply took a long flight. That’s since DVTs tend to form after you’ve been immobile for long periods of time.

Compression Stockings

These are long socks that squeeze your legs. The extra pressure helps blood relocation through your veins and leg muscles. Your doctor may recommend you wear them for a while after surgery.


Get out of bed and walk when you’re getting over a long remain in the health center or a disease that’s kept you in bed for too long. It’ll keep the blood in your legs flowing so it doesn’t have a chance to pool.
