DEEP VENOUS THROMBOSIS

Deep vein thrombosis is the consequence of the formation of a blood clot in a vein of large diameter, in the legs, arms, abdomen, etc. Deep vein thrombosis is a medical emergency because of its possible serious complications.

Deep vein thrombosis can occur spontaneously in a person with risk factors, or be the result of prolonged immobilization, damage to the walls of the veins or a decrease in the fluidity of the blood. All of these factors increase the risk of a clot forming in the deep veins.
