Causes in blockage of leg veind?

If you are referring to a varicose vein then it is not blocked it has a weakened valve and is ballooning. A blocked vein from a blood clot or "deep vein thrombosis" often happens as a result of inactivity for hours like sitting on a plane, or crushing trauma or hitting the leg and then getting a clot from a deep bruise.
If you do in fact have one of these, they can be life threatening; so a visit to your doctor or a call to your local ER consulting nurse would be in order.
If a bruise is ever bigger than the palm of your hand immediate medical attention is a must.http://en.wikipedia.org/wiki/Vericose_veins
