What is referred to as deep vein thrombosis?

When a blood clot (thrombus) forms in a deep vein, most commonly in the legs, the condition is known as deep vein thrombosis (DVT). Leg discomfort or edema may be signs of deep vein thrombosis. Symptoms don’t always present themselves.

Direct venous thrombosis can occur if a person already has a medical condition that alters the way blood clots. Likewise, inactivity can cause a blood clot to form in the legs. Long-distance travel, bed rest after surgery, illness, or an accident are all situations where you might not move around much.

Because of the risk of a blood clot-busting free in the veins, deep vein thrombosis can have devastating consequences. After forming, the clots can move through the circulatory system and lodge in the lungs, cutting off the oxygen supply (pulmonary embolism). Venous thromboembolism is the combination of deep vein thrombosis and pulmonary embolism (VTE).

How can thrombosis affect the human body?

Both the veins and the arteries are susceptible to thrombosis.

Arterial thrombosis:

This is thrombosis in the arteries, the vessels that carry blood away from the heart to the rest of the body. The leading cause of both heart attacks and strokes is arterial thrombosis.

Venous thrombosis:

This is an instance of thrombosis in the veins, the channels responsible for returning blood to the heart from the rest of the body. When a blood clot forms in a vein, it can travel to the lungs and cause a pulmonary embolism (blood clot in your lung). Seeking treatment for thrombosis is important to avoid severe complications of the condition.

Why is the location of clotting important?

Clots formed by thrombosis have the potential to obstruct blood flow, putting your health at risk. There are two possible outcomes:

Blockage where the clot occurs:

Thrombosis causes clots to develop and potentially expand until they are large enough to obstruct blood flow. Where and how large the clot originates will determine the obstruction’s severity.

Clots that lead to blockages in other places:

The chance of an embolus (plural of “embolus”) forming when a clot breaks out from its original site is significant in thrombosis cases. When it escapes into the bloodstream, it may go to tiny blood arteries and obstruct them (an embolism). Conditions like stroke and pulmonary embolism are often brought on by this (PE).

The signs that can indicate thrombosis are:

  • Leg swelling
  • Leg pain, cramping, or soreness that often begins in the calf
  • Leg skin that suddenly turns a different colour, say red or purple
  • A sensation of warmth on the affected leg

The different causes and risk factors that can lead to the condition:

A blood clot can be brought on by anything that hinders the blood’s natural ability to flow or clot.

Surgery, inflammation, infection, or injury can all cause permanent damage to a vein, which can lead to deep vein thrombosis (DVT); seek help from the vascular surgeons in Coimbatore to undergo the treatment.

The following can be risk factors can be associated with the condition:

Instances of deep vein thrombosis are more likely to occur because of a number of risk factors (DVT). The likelihood of developing a deep vein thrombosis increases as the number of risk factors you have multiplied. DVT risk factors include:


The danger of developing a DVT increases after age 60. DVT, however, can strike at any time, regardless of age.

Lack of movement:

Leg muscles, including the calf muscles, stop contracting when they aren’t used (contract). The contraction of muscles promotes circulation. The risk of developing a DVT increases when one sits still for lengthy periods, as one could do when driving or traveling. Long-term hospitalization or bed rest due to a medical condition like paralysis also causes this.


As a result of the growing fetus, the veins in your pelvis and legs are under more strain than usual. In some cases, the risk of blood clots caused by pregnancy can persist for up to six weeks following delivery. Those who have a genetic predisposition to blood clotting problems are at a higher risk.

Being overweight:

Vein pressure in the hips and legs rises when one is overweight.


The risk of deep vein thrombosis (DVT) can be raised because smoking alters the way blood flows and clots.


Specific individuals’ blood tends to clot more quickly because of inherited genetic variations. The factor V Leiden ad hoc exclusion phenomenon is one such instance. This genetic condition affects one of the blood’s clotting proteins. It’s possible that an inherited condition wouldn’t result in blood clots unless it was paired with additional risk factors.

The best treatment for thrombosis that is available:

Preventive medications:

Several kinds of drugs are used in combination with thrombosis prophylaxis. The items listed below are some examples of this type:

Blood thinners:

These drugs prevent excessive blood clotting.

Blood-pressure lowering medications:

High blood pressure causes excessive stress and damages your blood vessels’ inside over time. This type of wear and strain might facilitate the formation and growth of blood clots on the artery walls. Blood pressure drugs prevent blood clots by denying them new formation sites.

Deep vein thrombosis surgery:

Surgeon access and removal of a clot is one of the most direct methods of clot removal. Surgery may also perform a bypass, in which a segment of a healthy blood vessel from somewhere else in your body is used to create a diversion around a restricted section of another healthy blood vessel. It helps bring fresh blood back to the injured area, and this is one of the best vein block treatments that is used in case of serious thrombosis.

Outlook of the condition:

Although thrombosis is a significant medical issue, it rarely poses a threat until it persists for extended periods. Thrombosis, unfortunately, can rapidly escalate into a potentially fatal emergency. However, if you reach out to a blood clot hospital quickly, life-threatening consequences are rarely inevitable.
