Are there any connections between the deep vein thrombosis and pulmonary embolism?

Cause and effect: Deep vein thrombosis is a blood clot that forms in the veins, often in the legs, but also in other places. If a clot breaks loose and travels to the lungs, it is called pulmonary embolism. A pulmonary embolism can be fatal.

Definately: Deep venous thrombosis or DVT is a blood clot in one of the deep veins of the legs. The deep vein system lies in the center of the leg in between the major muscles. It connects with the large return vein in the pelvis (vena cava) which drains into the right heart. This leads to the lungs. Thus these clots can lodge in the lungs and be life threatening. Dvt is initially treated by blood thinners.
