A blood clot that forms in the upper leg vein is called a femoral vein thrombosis. A blood clot in the lungs is called a pulmonary embolism, or PE. Blood clots can form in many different parts of the body. “Platelets are the cells that circulate within our blood and bind together when they recognize damaged blood vessels,” says Marlene Williams, M.D., director of the Coronary Care Unit at Johns Hopkins Bayview Medical Center.“When you get a cut, for example, the platelets bind to the site of the damaged vessel, thereby causing a blood clot.

The embolus may be a blood clot (), a fat globule (fat embolism), a bubble of air or other gas (gas embolism), amniotic fluid (amniotic fluid embolism), or foreign material.An embolism can cause partial or total blockage of blood flow in the affected vessel. When traveling by car or plane, take frequent breaks to stretch legs and restore circulation. The clot may stay in one spot (called thrombosis) or move through the body (called embolism or thromboembolism). "Sometimes, an SVT can grow and become a deep-vein thrombosis." What Is a Blood Clot?
