What is Thrombosis?

Thrombosis is a condition that results in abnormal clotting of the blood. This can be triggered by a variety of conditions and diseases. If the clot occurs in a small vein it is called a superficial thrombosis, and it is rarely life threatening. Blood clots that form in major arteries or veins, especially those in the deep veins of the legs, can break off and cause a life threatening embolism. Look here for more information:
