Deep vein thrombosis (DVT) is also known as deep thrombophlebitis and is a condition where a blood clot develops in a deep vein. These deep veins are surrounded by muscle and located near bones. Located deeper under the skin, they return larger amounts of blood to the heart than do smaller surface veins.
Blood clots occurring in surface veins generally do not cause problems. Alternatively, deep vein clots require immediate medical attention because they pose potentially deadly results. These clots can dislodge, travel to the lungs and block blood flow. This condition is known as pulmonary embolism and is often fatal.
When the inner lining of a vein is damaged, it creates a situation where blood clots are more likely to form. Also, if you have blood that is more likely to clot or is thicker, you may be more prone to a blood clot. Those who are inactive for long periods of time may also be at risk. Surgery, injury, or cancer are also known to cause DVT.
Symptoms can include redness, swelling, or warmth in your legs. The calves or thighs can also feel achy or tender. However, should the clot be small, you may not experience any symptoms. A pulmonary embolism, in some case, may be the first sign of deep vein thrombosis.
Deep vein thrombosis is diagnosed through an ultrasound procedure that will measure blood flow, as well as identify any possible clots. If a DVT is found, treatment will start immediately to lessen the possibility of clot growth or a pulmonary embolism.
Treatment of this condition usually includes prescribing blood thinners such as Heparin or Warfarin. Regular blood tests are necessary to ensure that the medication is effective. In some very rare cases, a vena cava filler may be implemented to prevent clots from moving to the lungs.
Exercising, elevating your legs, and wearing compression socks may also be instructed.
