Blood clots can happen in veins. A blood clot in a vein close to the skin isn't likely to cause problems. But having blood clots in deep veins is called deep vein thrombosis. Deep vein thrombosis happens most often in the legs. This problem can lead to a blood clot in the lung (pulmonary embolism).
The deep veins of the leg have different terms to describe their location:
A person with a blood clot in a deep upper (proximal) leg vein is at increased risk for a blood clot in the lung or other complications.
