Blood clots are a common health concern for many people, particularly when they are exposed to news about clots spreading throughout the body and appearing in the lungs. The good news is that once you grasp how this is done, you can remain relaxed and be prepared in advance for what to look out for. You might think that it’s not very comforting, but with the facts, it’s not. At ViaScan, we help patients understand their risks and offer preventive lung and heart scans to detect potential issues early. There are no technical medical terms or clear facts that enable one to know what is going on with their body and when they must visit.

What is a blood clot? Where do they normally occur?

A blood clot is a patch that your body creates to stop the bleeding process. Just imagine it to be a bandage on your body. Blood clots are beneficial when they occur in the case of a cut, as they prevent excessive blood loss. However, in some cases, blood clots form in areas where they are not supposed to, such as in your blood vessels.

Which are the common locations of clotting?

The most usual places are the deep veins of your calves or thighs

  • Arms: Not very frequent, but possible
  • Pelvis: Occasionally, within the lower extremities of your pelvis
  • Other locations: Can develop in other body parts

When it occurs in a deep vein (it most often happens in your leg), you can be diagnosed with deep vein thrombosis or DVT. It’s like a livestock jam on your blood highway, which is unwarranted.

Why do the clots move to the Lungs?

Some of the reasons can be: 

  • Blood flow in your leg goes to the heart.
  • The blood flows into your lungs through your heart, which pumps it first.
  • The blood vessels in the lungs become smaller and smaller
  • The vein becomes too narrow, due to which the clot is stuck

A preventative lung scan can catch any blood clot that has travelled its way to your lungs. With clear imaging technology, you can take early action to improve your health. 

How Quickly Can a Blood Clot Travel from the Leg to the Lungs?

This is the question everybody would like to know! The trick is that you would be surprised by the answer. The rate varies according to several factors:

  • Clot size: The smaller ones move faster
  • Your heart rate: The quicker your heart rate, the quicker your travel
  • Blood flow: the quality of the blood circulation
  • Your activity level: Exercise influences blood circulation.

Important facts:

  • Not all leg clots make their way to the lungs
  • Some clots remain there and dissolve
  • Naturally, the body has a system to dissolve clots
  • Travelling can be prevented through rapid medical care

However, the most important thing to remember is that if you experience symptoms, do not wait to see if the clot travels or not; seek help directly.

What are the DVT early symptoms?

It is lifesaving to identify the early signs and symptoms of deep vein thrombosis. That is what to look out for:

General symptoms in your leg:

  • An enlarged leg compared to the other one
  • Pain: When walking, aching pain or cramping pain
  • Warmth: The area associated with the disorder feels hot when touched.
  • Redness: skin colour changes
  • Tenderness: it is painful to the touch

Important notes:

In most cases, only one leg is more involved than the other. Pain may manifest as a persistent cramp in a muscle that does not subside. If you experience them, particularly when they are sudden or occur more frequently, you should seek medical attention.

Which symptoms accompany a clot that has moved to the Lungs?

If a clot migrates to your lungs, it is referred to as a “pulmonary embolism,” and its symptoms differ substantially from those associated with leg clots.

Common signs Emergency signs
Shortness of breath: Suddenly, breathing becomes difficult Extreme chest pain
Chest pain Trouble breathing
Rapid pulse: Your pulse beats at a quicker-than-normal rate. Passing out
Coughing: There could be blood or pale, frothy foam brought up. Coughing blood
Leg symptoms: Can still experience pain or swelling in the legs

Is it possible to keep blood clots from moving?

There are numerous ways to avert the formation of blood clots and their movement:

Lifestyle prevention:

  • Keep moving:
  • Exercise: consistent physical movement aids healthy blood circulation
  • Stay hydrated by drinking lots of water.
  • Cease smoking: doing so elevates the risk of clots.
  • Maintain a healthy weight: Excessive weight puts pressure on veins.\

Medical prevention:

You may take medications that help prevent clots. Early detection combined with prompt treatment.  Health scans enable the detection of problems in the early stages.  Follow the movement recommendations provided by your physician.  Even minor movements help. Recognising the condition early is essential for averting serious complications. At this point, modern health screening services become crucial.

  • Ultrasound can detect blood clots in the legs.
  • CT scan: Shows any clots in the lungs
  • Whole-body scans: Thorough health screening
  • Lung scan: An imaging procedure dedicated to the lungs

Seek the professional assistance of qualified medical practitioners who will be able to determine the level of personal risk and advise accordingly on the necessary screening in relation to health history.

Conclusion 

The description of blood clots moving from the leg to the lungs may be frightening, but understanding how it occurs can help you remain calm and know what to do. It is essential to detect symptoms early and seek help promptly. And it all comes down to the fact that your body is spectacular at healing itself, provided you support it properly. Most individuals who get blood clots fully recover after treatment. It is good not to overlook symptoms and seek help when necessary.

In situations where you are concerned about your risk of developing blood clots and wish to learn about preventive health screenings, ViaScan offers a comprehensive health screening package that includes advanced imaging scans and full-body scans. One of the best investments one can make is to take charge of their health through early detection and prevention.


What-Causes-Pulmonary-Embolism.jpg
21/Apr/2025

Slightly after you have been breathing normally, do you feel like you’re going to drown? Even if you’re on dry land. The pulmonary embolism makes its mostly unwelcome announcement with this terrifying sensation. A pulmonary embolism occurs when a blood clot travels through the veins and blocks one of the arteries in the lungs that carry blood back to the heart. Each year, this dangerous condition affects thousands of Americans and can be fatal if not treated promptly. Allow us to explore this serious medical condition by answering some of the key questions about its causes and risk factors.

Why did Blood Clots travel to the Pulmonary Arteries?

Pulmonary embolism is most frequently caused by blood clots (which are simply clots of blood), formed in the deep veins of the legs (a condition called deep vein thrombosis, or DVT). Physical traits, such as these clots breaking free and travelling the bloodstream to the lungs, which they are prone to, are physical traits.

  • A blood clot’s journey takes place on a specific path.
  • Forms in a deep vein (usually in the legs)
  • Travelling through larger veins, it breaks loose.
  • Passes through the right side of the heart

It enters the pulmonary trunk (the main artery of the blood that passes through the heart to the lungs).

Small pulmonary arteries cannot accommodate their size and get stuck in them.

Since all blood passes through the lungs to pick up oxygen, all blood-borne clots will eventually end up in the pulmonary vessels unless they dissolve along the way. The pulmonary arteries branch so closely, creating trap points that clots can get wedged on the narrowing sections and stop blood flow to the tissue of some of this lung.

What Factors make a Patient at greater risk of having a Pulmonary Embolism?

Other things that can raise your risk of having blood clots that could develop into pulmonary embolism include:

Risk Category Specific Risk Factors
Medical Conditions • Cancer, Heart disease, COVID-19 infection and  Inflammatory bowel disease
Situational • Recent surgery or trauma, Extended bed rest, Long-distance travel 
Medications • Hormone replacement therapy and Birth control pills containing estrogen
Personal Factors • Pregnancy and postpartum period, Advanced age, Obesity and Smoking

 

A landmark study in the New England Journal of Medicine showed that cancer patients had an increased risk of developing venous thromboembolism (Venous thromboembolism includes pulmonary embolism) (Khorana et al., 2007).  

How does a Blood clot impact the Pulmonary Trunk and lung function?

When a blood clot lodges in the pulmonary trunk or any of the pulmonary arteries, it begins a chain reaction of events.

  • Blocks blood flow to portions of the lungs
  • Prevents proper oxygen exchange
  • Increases pressure in pulmonary vessels
  • Works harder than normal, causing the right side of the heart to work harder.
  • In severe cases, it can lead to right heart failure.

However, the symptoms depend on the size and location of the clot. Small clots in peripheral pulmonary arteries may cause little, if any, symptoms, and large clots that block the pulmonary trunk would be immediately life-threatening.

Can a Pulmonary Embolism present before there are Symptoms?

Weirdly, many sufferers of pulmonary artery blockages often present with little or subtle symptoms, which are more likely to be confused with other things. Common symptoms include:

  • Sudden shortness of breath
  • Pain that intensifies with forceful exhaling
  • Rapid heart rate
  • Cough (sometimes with bloody sputum)
  • Feeling lightheaded or dizzy

Nevertheless, it is estimated that up to 30–50% of pulmonary embolism cases are asymptomatic. Its silent nature makes it particularly dangerous because treatment delays compound mortality risk.

Why Early Screening for Pulmonary Embolism Can Be Life-Saving

Preventing the formation of blood clots is the best way to avoid pulmonary embolism. If you have risk factors, consider these preventive measures.

  • Do Not Sit Still – don’t sit for excessive periods
  • Stay hydrated, especially when travelling
  • Choose compression stockings for long flights

If prescribed, follow what your doctor recommends regarding blood thinners

Early detection is key to identifying concerning risk factors or symptoms. Viascan provides advanced imaging services that can help identify pulmonary embolism before it becomes life-threatening. Their latest CT pulmonary angiography can also detect even small clots in the pulmonary arteries, which can be addressed quickly and as soon as possible.
