TUESDAY, July 7, 2015 – People who suffer a blood clot in the lungs with no obvious cause can ward off a new clot with extended use of blood-thinning medications, a new study shows. However, the length of time those blood thinners should be given is unclear, since their benefits wear off soon after use is discontinued, the French researchers found. The clots are called pulmonary emboli, explained one U.S. expert, Dr. Richard Hayes. "Pulmonary emboli are clots in the blood vessels to the lungs that arise from the veins of the leg or thigh," said Hayes, a cardiologist at Lenox Health in New York City. One type of clot is deep vein thrombosis (DVT), often nicknamed "economy-class syndrome" because of cases occurring after long-haul flights. In many cases, Hayes said, there's a trigger – extended bedrest, obesity, recent surgery – for the clot, but in other cases the clots seem to arise ... Read more

TUESDAY, June 15 – CT angiography might not be necessary in many patients suspected of having a blood clot in the lung (pulmonary embolism), and a risk analysis can identify those most likely to require the procedure, a new study suggests. Pulmonary embolism (PE) occurs when a blood clot, usually from the leg, moves through the bloodstream and lodges in an artery in the lung. The condition can be fatal, so prompt diagnosis is essential. Because of its high sensitivity and specificity, CT angiography has become a preferred method of diagnosing PE. However, there are growing concerns about costs and patient radiation exposure, along with risks associated with contrast agents used in the procedure. For this study, researchers reviewed the medical records to assess the PE risk factors of 2,003 patients who underwent CT angiography for possible PE between July 2004 and February 2006. The ...
