Blood clots and vein disease

Deep vein thrombosis (DVT) is a condition in which a blood clot forms in the deep veins located in the leg, thigh, or pelvis. While Deep vein thrombosis (DVT) is common in the lower leg, it can also develop in other body parts, including the arms. So, how do blood clots form in the veins, and is it dangerous?

To answer this, let us look at how the blood circulates in the body. The blood circulatory system consists of two blood vessels, namely the arteries and veins. The arteries carry blood rich in nutrients and oxygen from the heart, while the veins carry the deoxygenated blood back to the heart. Arteries have thin muscles within their walls that make them capable of withstanding the pumping pressure from the heart. However, the veins have no muscle lining and entirely depend on the muscle movement to take the blood back to the heart.

How do Blood Clots Form?

The venous system in the legs consists of two main veins, the superficial veins, and deep veins. As the name suggests, deep veins are located deep within the muscles. On the other hand, superficial veins are located just below the skin and are easily visible. Typically, the blood flows from the superficial veins into the deep venous system through perforator veins. Both the perforator and superficial veins have valves that allow blood to flow in one direction.

However, when blood travels slowly in the veins or pools in the veins, the platelets tend to stick together. While a blood clot (thrombus) in the deep venous system of your leg is not dangerous by itself, it can become life-threatening when it breaks and travels to enter the pulmonary vein. When the blood clot blocks a pulmonary artery, it decreases the amount of oxygen absorbed in the blood, causing a life-threatening condition known as pulmonary embolism.

Deep vein thrombosis (DVT) is considered a medical emergency. According to the CDC (Center for Disease Control and Prevention), 10 – 30 percent of individuals who develop leg DVT experience life-threatening complications within a month of diagnosis.

DVT SYMPTOMS

Like other disorders that affect the venous system, some individuals with DVT may not notice any symptoms. However, if the symptoms develop, people with deep vein thrombosis (DVT) may experience the following:

Leg pain with walking (muscle cramp or sharp pain)
Sharp pain in the affected limb that starts in the calf
Red or discolored skin on the affected limb
Swelling in the affected limb
Sudden onset leg swelling
Enlarged veins
Increased warmth in the swollen, painful region

Most often, deep vein thrombosis (DVT) affects only one leg, although, on rare occasions, the condition may develop in both legs. If the blood clot (thrombus) breaks and travels up to the lung, a person suffering from pulmonary embolism may have the following:

Sudden breathlessness or slow breathing
Rapid breath
Increased heart rate
Chest pain that worsens when breathing deeply

Swelling or Edema?

Swelling or Edema?

Swelling or Edema

Swelling in the legs (edema) occurs when fluid becomes trapped in the soft tissues of the leg from malfunctioning valves in the veins. When the valves in leg veins begin to weaken, or fail, the blood can no longer be pumped out of the legs properly. This causes fluid and blood to become trapped in the legs. When the fluid begins to build up, the leg may begin to swell. The term for the buildup of fluid which leads to swelling in the body is edema.

Lymphedema

Lymphedema is a form of chronic edema that occurs when the body’s lymphatic system does not function properly. It is not the same as vein-disease related edema, although vein disease can eventually progress into a combined venous/lymphatic disorder. As with swelling in the lower legs, lymphedema requires the attention of a healthcare professional as soon as possible.

Who is at risk?

Any swelling in the lower leg should be considered abnormal, and patients must visit a physician immediately to diagnose and begin treating the underlying problem. Swelling can also be a symptom of other, non-venous conditions such as heart disease, heart failure, obesity, high blood pressure, liver disease, or kidney disease, so it’s important to seek medical attention immediately.
