What Are The Symptoms Of Pulmonary Embolism
Symptoms of pulmonary embolism vary, depending on the severity of the clot. Although most people with a pulmonary embolism experience symptoms, some will not. The first signs are usually shortness of breath and chest pains that get worse if you exert yourself. You may cough up bloody sputum. If you have these symptoms get medical attention right away. Pulmonary embolism is serious but very treatable. Quick treatment greatly reduces the chance of death.
Symptoms may include:
- Sudden shortness of breath whether youve been active or at rest.
- Unexplained sharp pain in your chest, arm, shoulder, neck or jaw. The pain may also be similar to symptoms of a heart attack.
- Cough with or without bloody sputum .
- Pale, clammy or bluish-colored skin.
- Rapid heartbeat .
- In some cases, feeling anxious, light-headed, faint or passing out.
It is also possible to have a blood clot and not have any symptoms, so discuss your risk factors with your health care provider.
If you have any symptoms of pulmonary embolism, get medical attention immediately.
Recovery From Mechanical Thrombectomy
After the procedure, patients remain in the hospital for observation. While some may recover in an ICU, Dr. Mina says most patients he sees are admitted to a step-down unit these units are for patients whose illness does not require ICU care.
That is a benefit of having a PERT team because we can get patients the care they need quickly, potentially reversing the strain on the heart and avoiding ICU admission, he said.
While many patients go home within one to two days, the length of stay in the hospital and recovery depends on how long the blood clot impacted blood flow and the type and extent of disease. When thrombectomy is done in an outpatient setting, which is done only for DVT, it is possible for patients to go home within a few hours of the procedure.
What Causes Blood Clots In The Lungs
Pulmonary embolism can be caused by many factors:
- Surgery, especially surgery on the abdomen, hip, and knees
- Bone fracture, especially long bone fractures such as of the thigh bone
- A long period of confinement to the bed or a wheelchair
- Prolonged hospitalization
- Direct oral anticoagulant medications

Treatments For Large Blood Clots In The Lungs Blocking Major Arteries
Sometimes, you can have normal blood pressure, but still have large blood clots in the lungs blocking multiple major branches of the pulmonary artery, as seen in this picture. If your blood pressure is low, you will get the exact same treatment we discussed earlier. However, if you have large blood clots but a normal blood pressure, you may not need all of those high-risk treatments.
You still need to get started on heparin like we discussed earlier. After that, if your blood pressure is still stable, most doctors simply decide to watch you closely in the hospital. They will monitor your blood pressure closely during the hospital stay. If your blood pressure drops, you will get the more invasive treatments. If your blood pressure remain stable, you may only need blood thinners.
Some places may still offer you catheter guided treatments for large clots even when your blood pressure is fine. That is an important and individualized decision you need to make with your doctor after discussing the risks and benefits.
Will I Be Treated In Hospital Or At Home
As part of your diagnosis, you should have had an assessment to check the risk of coming to harm from the pulmonary embolism. If you are thought to be at intermediate or high risk of coming to harm, then you will be treated as an in-patient in hospital. If you are deemed to be at low risk of coming to harm then you may be diagnosed and treated as an outpatient.
If you are managed as an outpatient, you should be reviewed by a senior clinician before going home. You should also be given information on potential complications and treatment, as well as a point of contact at the hospital.
If its confirmed that you have had a pulmonary embolism and are being treated as an outpatient, you should have an initial review within seven days of being discharged. You should also have a later follow-up check with a senior clinician with expertise in pulmonary embolism management.

Treatment Of Pulmonary Embolism That Is Not High Risk Blood Thinning Medication
Most pulmonary embolisms that present to hospital are not massive or submassive and fall in to a category that is generally lower risk. The mainstay of treatment for these is blood-thinning medications. Blood thinning medications prevent the clot from enlarging and allow the body to naturally break down the clots. Patients will have to stay on blood thinning medication from 6 months to life long depending on the circumstance.
- Heparin Initially heparin used. This is a commonly used blood thinner and typically given in the form of a drip. The dose of heparin can be adjusted as necessary to ensure adequately thin blood. This may be transitioned to an injectable form of heparin such as lovenox.
- Warfarin This is the longest standing medication used for blood thinning. This is taken as a tablet and it takes a few days to get the blood thin. Its levels are monitored with a blood test. The downside is that the blood needs periodic monitoring to ensure levels are in the desired range, and there are some dietary restrictions.
- NOACs Short for novel anticoagulant agents. These include Rivaroxaban, Eliquis, Pradaxa, Savasya and others. These are given in tablet forms and the advantage is that monitoring of blood levels is not required.
Treatments For A Cardiac Arrest Due To Blood Clots In The Lungs
As you already know from reading the article on symptoms of blood clots in the lungs, cardiac arrests are one of the symptoms of a blood clot. Unfortunately, many people with a pulmonary embolism die before they can get to a hospital.
The most important treatment for people that suddenly collapse due to a blood clot in the lungs is to start CPR right away. If you are CPR certified or know how to do CPR, you should start it as soon as possible, and have someone call 911. If you can find someone nearby who can perform CPR, you should tell that person to start CPR and then call 911 yourself.
The picture above shows how CPR can save someone in cardiac arrest due to a blood clot in the lungs. A sudden cardiac arrest happens with a pulmonary embolism when blood flow to the lungs is completely or almost completely blocked by the clot. When repeated chest compressions are performed with CPR, the force of the chest movement may push the clot out, and it may slide forward, creating an opening for blood to start flowing again. This blood flow may sustain life until the patient can be transported to the nearest emergency department and more advanced treatment can be started.
In people with major blood clots in the lungs leading to cardiac arrest, quick CPR is the most important treatment that makes a difference between life and death.

What Causes Pulmonary Embolism
Pulmonary embolism may occur:
- When blood collects in a certain part of the body . Pooling of blood usually occurs after long periods of inactivity, such as after surgery or bed rest.
- When veins have been injured, such as from a fracture or surgery .
- As a result of another medical condition, such as cardiovascular disease or stroke.
- When clotting factors in the blood are increased, elevated, or in some cases, lowered. Elevated clotting factors can occur with some types of cancer or in some women taking hormone replacement therapy or birth control pills. Abnormal or low clotting factors may also occur as a result of hereditary conditions.
Treatments For Blood Clots In The Lungs
The treatment for blood clots in the lungs depends on the severity of symptoms. Blood clots in the lungs are also called pulmonary embolisms. In the last 15 years, I have personally treated hundreds of patients hospitalized with blood clots in their lungs. I am writing this article based on my experience as well as a thorough review of medical literature.
Before reading this article, I suggest you read symptoms of blood clot in the lungs. Once you understand the different types and severities of the symptoms, you will better understand the treatment options.
Unlike large corporate medical websites, I will not simply tell you about all the different medications and procedures that are available to treat blood clots in the lungs. I will tell you who needs what kind of treatment based on the severity and specifics of the situation. You can use this information to work with your doctor and better understand your treatment options.
Here are the specific situations we will explore:

How Are Blood Clots Diagnosed
Blood clot symptoms can mimic other health conditions. Doctors use a variety of tests to detect blood clots and/or rule out other causes. If your doctor suspects a blood clot, he or she may recommend:
- Blood tests can, in some cases, be used to rule out a blood clot.
- Ultrasound provides a clear view of your veins and blood flow.
- CT scan of the head, abdomen, or chest, may be used to confirm that you have a blood clot. This imaging test can help rule out other potential causes of your symptoms.
- Magnetic resonance angiography is an imaging test similar to a magnetic resonance imaging test. An MRA looks specifically at blood vessels.
- V/Q scans test circulation of air and blood in the lungs.
Diagnosis Of Pulmonary Embolism
Once a patient comes in with signs and symptoms suggestive of a pulmonary embolism, a number of tests can be performed to confirm the diagnosis.
This is an echocardiogram that demonstrates a large amount of clot seen floating in the right side of the heart as it passes through on its way to the lung where is will result in a pulmonary embolism.
A pulmonary angiogram demonstrating a huge clot that has lodged in the artery of the lung. This clot was so large that it caused the heart to stop and required urgent aggressive treatment.
Another pulmonary angiogram in a patient with a large pulmonary embolism. Contrast dye is injected in to the lung where large areas of clot are seen throughout the arteries of the lung.

Recognize The Signs And Symptoms Of Blood Clots
Contact your cancer doctor if you experience any of these signs or symptoms of a blood clot.
Signs and symptoms of a blood clot in a persons leg or arm may include:
Swelling
Pain or tenderness not caused by injury
Skin that is warm to the touch
Redness or discoloration of the skin
Seek immediate medical attention if you experience any of these signs or symptoms of a blood clot.
Signs and symptoms of a blood clot in a persons lung may include:
Difficulty breathing
Chest pain that worsens with a deep breath or cough
Coughing up blood
Faster than normal or irregular heartbeat
How Is A Pulmonary Embolism Diagnosed
If your doctor thinks you may have a pulmonary embolism, they will talk to you and examine you.
You will be asked to have some tests, such as:
- electrocardiogram
- imaging such as a chest x-ray, CT scan, ultrasound or one known as a ventilation-perfusion scan, which measures both air flow and blood flow in your lungs
If you are low risk of having a pulmonary embolism, you may not need extra scans. The Royal Australian and New Zealand College of Radiologists recommend that if your doctor suspects you have a pulmonary embolism, you should ask about the most appropriate test for diagnosis.

Treatment Of Massive Pulmonary Or High Risk Submassive Pulmonary Embolism
These are a medical emergency and immediate treatment is needed there are a few different treatment options. Often the treatment chosen will depend on what is available at that facility.
This is a fluoroscope video of 2 special tubes known as catheters that are passed through the veins of the leg into the arteries of the lung. These EKOS catheters emit ultrasound waves that make clot-busting medicines very effective at small doses. Clot busting medicines are slowly dripped through these catheters that will dissolve the lung clot.

Infusion Of Blood Thinners
A blood thinner called heparin is infused in all patients with life-threatening blood clots in the lungs, regardless of which of the above treatment options are used. Treatment is started as soon as blood clots in the lungs are suspected or confirmed. Heparin is used unless there is any specific problem in someone that prohibits its use. Unlike TPA, heparin is simply a blood thinner. Blood thinners prevent the formation of new clots. They weaken the clot-forming mechanism in our bodies, but do not directly dissolve the clots. The main goal of infusing heparin is to prevent new clots or an extension of an existing clot.

What To Think About
Vena cava filters aren’t typically recommended as the first treatment for pulmonary embolism. But they may be used in some people. For example, they may be used if a person cannot take anticoagulant medicine.
Vena cava filters can cause serious health problems if they break or become blocked with one or more blood clots.
Improving The Technology Outcomes
The evolution from surgical thrombectomy to mechanical thrombectomy has improved outcomes and been revolutionary across multiple fields of medicine, says interventional cardiologist Varinder Singh, MD, chair of cardiovascular services for the northwest region of Northwell Health, and chair of cardiovascular medicine at Lenox Hill Hospital.
For a long time, we really didnt have much treatment for pulmonary embolism, he said. It was either do some invasive surgery which they werent going to survive, or give the clot-busting medications. Now, we have something in the middle where if the patient is the right patient and they meet the criteria, we can restore blood flow. This really has opened up a whole new mechanical space for us.

What Increases Your Risk
Having a blood clot in the deep vein of your leg and having a previous pulmonary embolism are the two greatest risk factors for pulmonary embolism.
For more information on risk factors for blood clots in the legs, see the topic Deep Vein Thrombosis.
Many things increase your risk for a blood clot. These include:
- Having slowed blood flow, abnormal clotting, and a blood vessel injury.
- Age. As people get older , they are more likely to develop blood clots.
- Weight. Being overweight increases the risk for developing clots.
- Not taking anticoagulant medicine as prescribed, unless your doctor tells you to stop taking it.
A Variety Of Risk Factors Contribute To The Development Of Pulmonary Embolism:
- Surgery, particularly abdominal or orthopedic surgery, such as hip or knee surgery
- Trauma or bone fracture
- A long period of bed rest or sitting for a long time, perhaps on an airplane or in a car
- Cancer and some cancer treatments, like chemotherapy
- Cardiovascular diseases such as atrial fibrillation, heart failure, heart attack or stroke
- Pregnancy and the first 6 weeks after giving birth
- Birth control pills or hormones taken for symptoms of menopause
- Family history of blood clots
- Inherited blood disorders that make the blood thick, such as thrombophilia
- Inflammatory bowel disease
- Auto-immune diseases, such as lupus or antiphospholipid syndrome

Al Roker Is Recovering After Being Hospitalized For Blood Clots
Al Roker has revealed he has been recently hospitalized and receiving treatment for blood clots.
The Today weatherman has been absent from the show for two weeks and talked about his condition on , writing, So many of you have been thoughtfully asking where Ive been.
Last week I was admitted to the hospital with a blood clot in my leg which sent some clots into my lungs, he wrote. After some medical whack-a-mole, I am so fortunate to be getting terrific medical care and on the way to recovery, he added.
Roker signed off with, Thanks for all the well wishes and prayers and hope to see you soon. Have a great weekend, everyone.
Filling in for Roker has been Dylan Dreyer, alongside Savannah Guthrie, Hoda Kotb, Craig Melvin and Carson Daly, who all wished their colleague well.
Hes in good spirits, weve all talked to him, Guthrie said.
Its hard to slow down Al but hes on the mend and hes on the way to recovery, Guthrie added. I dont know if he watches this show but we love you, Al. We miss you.
