...When arteries to the penis have become constricted, surgery can sometimes restore blood flow. In one operation, called an endarterectomy, the blood vessel is opened and scraped clean. Doctors also bypass blockages by grafting sections of an abdominal artery around narrowed branches of the iliac artery that lead to the penis. This operation is similar to the one done on clogged coronary arteries, but does not have as high a success rate. Vascular surgeon Ralph DePalma of Washington thinks that vessels to the penis are more fragile because they are subjected to sudden surges in blood pressure...
...through the diaphragm, punctured the left ventricle-the heart's major pumping chamber-and entered the aorta, the main artery of the body. Like a log in a swift stream, it was carried by the blood round the aorta's bend, down the chest into the left iliac, a major blood vessel feeding the leg, where it finally came to rest. Had the bullet taken a different course-blocking an artery to the head, say-Rojas would have died immediately...
...surgical procedure doctors carried out on Richard Nixon is relatively common and uncomplicated. Opening Nixon's abdomen just above the groin, Dr. Eldon B. Hickman clamped a 1½-in. serrated plastic clip across the iliac vein from Nixon's left thigh, just above the spot where a clot, discovered last week, had formed. Hickman said later that he could "readily palpate [feel]" the clot during the operation. The teeth of the clip (called a Miles clip, after the physician who invented it in 1962) were closed, creating a sluicelike effect that permits blood-but not large clots...
Some medical experts wondered why the surgeons did not tie off the large vein known as the inferior vena cava. That step could block the passage of clots that might form later on higher in the left iliac vein or in Nixon's right leg or in tributary veins from the left leg. It is not known how extensively during surgery the doctors examined the inferior vena cava for possible clots...
...stay at the Annenberg estate in Palm Springs early in September. At some point, Nixon's physicians say, a part of that clot, or possibly a new one, broke loose. The embolus was carried away in the bloodstream, like debris in a fast-flowing river, through the iliac vein and the inferior vena cava into the heart (see diagram...
