When these valves become inflamed-it may be from injury, infection, some forms of cancer or simply sluggish blood flow from inactivity-some blood is likely to be trapped in a pocket where it forms a clot. 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...
Moreover, Dr. James F. Mustard of Hamilton, Ont., asked for a new look at the phenomenon of clotting inside blood vessels, including coronary arteries. In the past ten years, he said, it has been shown that formation of a thrombus that will plug an artery is a complex process following an inflammatory reaction and involving an aggregation of platelets, the smallest solid elements in the blood. It may be possible, he suggested, to use anti-inflammatory drugs to control or prevent some kinds of thrombus formation. But by the same token, it may be unwise to give such drugs-even...
Shortly after dawn, the patient was hoisted to a crude table in his home near the Yugoslav village of Krasic. Surgeon Branislav Bogicevic examined the dangerous clot in his right leg, decided to tie off the affected vein without removing the thrombus. At week's end, Surgeon Bogicevic reported that his patient, maligned, maltreated Aloysius Cardinal Stepinac, was out of danger...
