Explanation of Condition

Blood clot in a blood vessel, usually a deep vein of the leg, although the arm or any other part of the body may be affected. Can be provoked (for example after a long haul flight) or unprovoked. Occasionally a clot will become dislodged and travel to the lungs, via the heart, which may be life-threatening (pulmonary embolism).
