The danger then is that the clot, or thrombus, will begin to travel toward the heart and lungs...
Deeper Danger. When a thrombus does travel, it is called an embolus. The likelihood of an embolus appearing is negligible when the inflamed vein is near the skin's surface; it is vastly greater, however, if the clot forms in one of the large, deep veins. That is what apparently happened in Nixon's case. For some time after its formation in a vein deep in his left leg, the clot stayed in place. There, it caused the intermittent but painful swelling that bothered Nixon on his trip to the Middle East last June and, more severely, during...
Nixon's ailment is a common one that annually afflicts more than 300,000 Americans. Thrombophlebitis is an inflammation of a vein (phlebitis) accompanied by a clot (thrombus) that has formed in the vein. It may occur anywhere in the body, but is most common in the legs, where clots seem to form more easily. People who sit or stand for long periods are particularly susceptible, as are patients recovering from childbirth or surgery-one reason doctors get them out of bed as soon as possible. Once one is afflicted, however, bed rest (with the limb elevated) is usually...
