Deep Vein Thrombosis – Symptoms and Diagnosis

Symptoms and Diagnosis

Vein Thrombosis

Deep Vein Thrombosis or DVT is a condition in which blood clots can form within the deep veins of the body. A clot can occur when the blood becomes thicker and clumps within in one area. Deep vein clots usually occur in the calf, thigh or other parts of the leg but they can occur within other areas of the body.

Although a knock or injury may result in a bruise, this swelling it is actually a small clot in the superficial vein which is perfectly harmless and will dissipate by itself. Deep vein clots can be far more problematic as there is a risk that the clot can become dislodged and flow into the lung or heart. If this clot is of a significant size, this can cause severe complications or even death.

Common Symptoms

The symptoms of deep vein thrombosis can be very subtle. The clearest indicators are swelling or pain in the leg or lower limbs. Usually the pain or swelling is restricted so that it only affects one side.

A common site is the calf. The development of redness or swelling can indicate a problem. It will also be extremely tender when applying pressure to the back of the thigh or calf. In a case of deep vein thrombosis when comparing the affected calf with the other a significant difference will be visibly demonstrated.

However in some cases swelling is not visible but the limb feels suddenly warm for no apparent reason, feels tired or restless or you are experiencing a pain which only occurs when you are standing or walking, this could also be a symptom.
