Venous Thrombosis

Venous Thrombosis also known as Deep Vein Thrombosis (DVT) is defined as a blood clot or thrombus which occurs in a deep vein. This usually occurs in the legs. Blood clots accompanied with inflammation in the superficial veins do not usually cause serious problems. However, the blood clots in the deep veins require an immediate medical action.

The blood clots in the deep vein are deemed dangerous because these can break loose from the vein, travel through the person's bloodstream towards the lungs and block blood flow in that specific body organ. This condition is called pulmonary embolism. Pulmonary embolism is oftentimes life-threatening. Aside from embolism, DVT can also lead to other long-lasting health problems. It can damage the vein and cause pain in the leg. It can also make the leg swell and change in color. After many years of having DVT, leg sores may also appear. Blood clots develop in the calf and thigh veins, but it can also occur in the arm or pelvic veins.

How Do Deep Vein Clots Form?
Being inactive can lead to the formation of blood clots in veins. Injury or a surgery that has damaged your blood vessels can also cause clots to form. Also, cancer can cause venous thrombosis.

Can DVT have Symptoms?
Usually, venous thrombosis is indicated by swelling of the affected leg. In addition, the leg may look redder than the other leg and it may feel warmer. When you touch or squeeze the calf or thigh or when you stand or move, you will feel pain or tenderness. The pain that you experience may last long and it may also get worse over time. In some cases, pulmonary embolism is the first sign of DVT. But if the blood clot is small, it may not show any symptom at all.

How Do Doctors Diagnose Venous Thrombosis?
Doctors usually advise their patients suspected of having venous thrombosis to undergo an ultrasound test in order to check the blood flow through the veins and find the locations of blood clots. Anther test used to diagnose venous thrombosis is venogram. Venogram is an x-ray test which can take pictures of the blood flow through the patient's veins.

Is There any Cure For DVT?
The treatment starts by reducing the blood clot in order to prevent clots that might break loose and reach the patient's lungs. Another way to treat DVT is by having the patient take blood thinners or anticoagulants like heparin or warfarin. These blood thinners must be taken regularly for at least three months to prevent the growth of existing blood clots. Blood tests are also frequently done to check how well the blood thinners are working. Doctors may also advise the patient to elevate the leg affected with DVT. Walking and wearing compression stockings can also help to reduce the swelling and the pain.
