Deep Vein Thrombosis: Causes, Picture, Symptoms and Treatment

Deep vein thrombosis (DVT) as the name suggest blood clot forming in the deep vein. But, it times the problem triggers due to no apparent reason.

Therefore, the incidents that force you in the confinement of a bed can trigger the DVT.

What Is Deep Vein Thrombosis (DVT)?

It is the condition triggered due to the formation of thrombus or blood clots. In most cases, patients may develop blood clots in one or more veins. The deep veins in the legs are more susceptible to the problem. So, it can lead to swelling in the leg or severe pain. But, some people may experience no signs. It is a serious condition that can result in a fatal condition. The blood clots in veins can break from the legs and travel to the lungs. It can lodge in the veins of the lungs and trigger pulmonary embolism. The condition can block the blood flow in the lungs. Therefore, it can lead to fatal complication including death.

Symptoms Of Deep Vein Thrombosis

deep vein thrombosis So, how do you know you experience some problem? You need to monitor your body closely. Some people may not find any signs associated with the problem. But, in most cases, you may see signs. Therefore, the common symptoms linked to the problem are:

  • Warm feeling in the affected area. It occurs mostly in the leg.

Causes Of Deep Vein Thrombosis

The problem with blood circulation is the main cause triggering the deep vein thrombosis. So, the clots form in the vein when the blood clotting reduces or something prevents blood circulation. The problem that triggers the issue are:

  • Surgery
  • Injury or trauma to a vein
  • Side effects of certain medication
  • Limitation of movement

Risk Factors Associated With Deep Vein Thrombosis

Some people are more at risk of developing DVT compared to others. So, what makes them vulnerable to the disease? The following factor increases the possibility of getting the problem:

Inheriting Blood Clots Disorder

Inheriting Blood Clots Disorder

The inherited blood clotting problem can trigger the issue. It can lead to developing of clots when combined with other risk factors.

Staying Inactive For A Long Time

Prolonged bed rest due to paralysis or hospital stay to increase the risk of DVT. The condition can make your legs remain still. So, it leads to improper blood circulation in the calf muscles. It can trigger blood clots.

Pregnancy can increase the pressure in the veins of the legs and pelvic region. Women who have inherited blood clotting disorder can experience the problem more.

HRT or BC Pills

Hormone replacement therapy or birth control pills can increase the risk of getting blood clots.

Excess Weight

Obesity or overweight people experience the pressure in the veins of legs as well as the pelvis. It can trigger DVT.


Old people above 60 years of age can get affected by the problem more compared to others.


People with a family history of Deep vein thrombosis have more chance of developing it.


When you smoke, it affects the blood circulation as well as the clotting adversely. So, it increases the risk of developing clots.


Some forms of cancer can elevate the substances in the blood that can increase the risk of clotting. In other cases, some cancer treatment can also put a patient at risk of developing blood clots.

Heart Failure

Heart Failure

Patients who have suffered heart failure have limited lung and heart function. So, it increases the risk of deep vein thrombosis and subsequent pulmonary embolism. Even a small clot can trigger pulmonary embolism, which becomes more noticeable.

Complications Due To Deep Vein Thrombosis

The deep vein thrombosis triggers several health complications if left untreated. So, you need to provide ample importance to getting treatment at the right time. Some of the main problems associated with the DVT are:

Pulmonary Embolism

Pulmonary Embolism

It is the most serious or severe complication associated with the DVT. The problem occurs when a blood clot from other parts of the body enters the lung. So, the clot can result in the blood vessel in the lung to get blocked. In most cases, the blood clot known as thrombus travels from the leg to the lung. It is a life-threatening condition.

  • Severe discomfort while coughing
  • Rapid pulse

Postphlebitic Syndrome

Postphlebitic Syndrome is another common complication associated with DVT. It is the severe problem that reduces the quality of life. Therefore, the problem also known as post-thrombotic syndrome can cause damage to the vein. It leads to a reduction in the blood flow. So, the affected area can experience severe issues like:

  • Leg pain

Diagnosis Of Deep Vein Thrombosis

When you experience the signs or symptoms associated with the problem, you need to get a doctor’s appointment. Your doctor can check for the symptoms and diagnose the problem. So, your doctor adopts the following diagnostic techniques to detect the issue:

Blood Test

The doctor can suggest some blood tests. The blood sample sent to the lab will test for a substance known as D dimer. So, if you suffer from DVT problem, then you have elevated levels of D dimer.


It creates an x-ray image of the veins in the areas like feet and legs. During the procedure, your doctor injects the dye into the large vein in the ankle or foot region. It is an invasive method. Today, non-invasive imaging techniques can provide a clearer picture of the clots.

CT Scans/MRI Scans

It is the sophisticated imaging techniques that provide visuals of the clots with better clarity. Most of the times, the images can reveal the size, severity, a specific location of the clots in-detail.

Treatment To Overcome Deep Vein Thrombosis

The treatment of DVT aims at stopping the clot from increasing its size. It focusses on avoiding the clot to break loose and result in pulmonary embolism. Pulmonary embolism can result in a fatal complication. Therefore, the treatment aims to reduce your chances of suffering from the issue again and prevent its recurrence. Depending on the diagnosis and the severity of the condition, your doctor can suggest the following treatment options:

Blood Thinners

But, it prevents the formation of new clots and prevents existing ones from getting bigger. So, you can take it to prevent the DVT. It is available in the form of pills or injections. In the case of injectable thinners, you take a shot under the skin. You can also inject it through the veins in your arms (intravenous). Your doctor can suggest taking in three ways:

Clot Busters

Clot Busters can treat the more serious form of deep vein thrombosis. It is also effective for pulmonary embolism. In the majority of cases, the clot busters work well when other medications do not work well. The clot busters also known as thrombolytics can break the clots swiftly. The clot busters are given in two ways. One method includes giving the drugs through the IV line. Another method uses a catheter. It is placed directly on the clot to alleviate the problem. But, you need to understand that it can trigger serious bleeding. So, your doctor may suggest it only for severe cases of blood clots.
