The Link Between Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE)


Blood clots can cause a wide range of serious health conditions, including deep vein thrombosis and pulmonary embolisms. Deep vein thrombosis involves a blood clot in a deep vein that typically forms in a leg, while a pulmonary embolism occurs when that clot travels to the lung. Untreated deep vein thrombosis frequently develops into a pulmonary embolism, which can be a much more serious condition that makes handling even seemingly minor leg problems as soon as you notice them more important than you might think. Here are some of the most important things to know about the relationship between deep vein thrombosis and pulmonary embolisms, as well as how Supreme Vascular and Interventional Clinic can help Singapore residents and visitors manage these conditions.


What Is Deep Vein Thrombosis? 


Deep vein thrombosis is a condition that occurs when a blood clot, which is also known as a thrombus, forms in a deep vein in a leg or elsewhere in the body. While not all patients with deep vein thrombosis develop any symptoms, this condition is often characterized by pain, cramps, swelling, and warmth in the affected leg. The color of the skin around the clot may also change to a purple or deep red shade. Deep vein thrombosis is most frequently caused by recent leg surgery, an infection, or another type of injury. You may be more likely to develop deep vein thrombosis if you live a mostly sedentary lifestyle, are over age 60, are pregnant or overweight, are taking contraceptives, have heart disease or cancer, or smoke. It is also commonly seen in individuals on long haul flights. 

This condition is generally diagnosed using a D-dimer blood test, duplex ultrasound, venography, or an MRI and treated with blood thinners and compression stockings. Some patients need vein filters. Untreated deep vein thrombosis may quickly develop into a pulmonary embolism.


What Is a Pulmonary Embolism? 


A pulmonary embolism is caused by a deep vein thrombosis clot that migrates through your bloodstream and prevents blood from flowing into your lungs properly. In addition to the typical risk factors associated with developing deep vein thrombosis, you may be more likely to have this condition develop into a pulmonary embolism if you have a family history of pulmonary embolisms, you have had recent surgery, or you have heart disease, cancer, or a condition that affects your blood’s ability to clot properly. This condition is generally diagnosed through various types of tests, such as:

  • Various blood tests
  • Chest x-rays
  • An ultrasound
  • CT pulmonary angiography
  • Ventilation-perfusion scan
  • Pulmonary angiogram
  • MRI

Pulmonary embolisms are often treated with similar medications to deep vein thrombosis, although surgery may also be needed to remove the blood clot if its position makes it too urgent to wait for medications to work or your medications do not work.


The Link Between Deep Vein Thrombosis and Pulmonary Embolisms


While not all deep vein thrombosis cases will develop into pulmonary embolisms, understanding the frequency of this link is an important step in avoiding serious complications that may be associated with slight leg soreness or other seemingly minor symptoms. Approximately 60-80 percent of individuals with deep vein thrombosis eventually develop a pulmonary embolism if their condition is left untreated. Around half of pulmonary embolisms produce no immediate symptoms, but they still have the potential to lead to more serious complications.

Like many similar conditions, making certain lifestyle adjustments can significantly improve your early deep vein thrombosis symptoms and reduce their likelihood of developing into something more serious. Exercising more, eating more nutritious foods, quitting smoking, and other adjustments can significantly improve the overall health of your blood and make it less susceptible to significant clotting. Continuing to monitor your deep vein thrombosis over time can also help your doctor notice early signs of a pulmonary embolism or other more significant problem as early as possible to begin treatment when it is most likely to be successful.
