Blood Clots Directory

Blood clots happen when substances in the blood clump together as a result of injury to a blood vessel. The substances, called platelets, "plug" the damaged area to prevent blood leakage. Trouble or complications happen when the clot creates a blockage. Clots create other potential problems when bits of them break off and travel to other parts of the body. When clots travel to other parts of the body and cause a blockage, there is the potential for a stroke, clots in lungs (called pulmonary embolism) or clots in the deep veins of the body (called deep vein thrombosis).
