FAIRFAX, Va.ATTRACTthe first major national trial of a catheter-based treatment for deep vein thrombosiswill evaluate the use of clot-dissolving drugs in combination with clot removal devices to prevent post-thrombotic syndrome in patients with DVT (the formation of a blood clot in a leg vein). PTS, a common irreversible complication of DVT, causes permanent damage to the veins, resulting in debilitating chronic leg pain, swelling, fatigue and/or skin ulcers. About 25 percent of DVT patients develop PTS when treated with blood thinners alone. While early treatment with blood thinners is important to prevent a life-threatening pulmonary embolism, blood thinners alone do not dissolve the existing clot, which remains in the leg. Preliminary studies have shown that interventional clot-busting treatments canunlike standard DVT therapyremove clots and have strong potential to prevent PTS. The outcomes of this pivotal multicenter trialto be funded at more than $10 million by the National Institutes of Health's National Heart, Lung and Blood Institute (NHLBI)are likely to change the way DVT is treated in the United States.
"The ATTRACT trial could fundamentally shift the 50-year-old DVT treatment paradigm to one that includes interventional clot removal as an essential element of standard DVT care," said interventional radiologist Suresh Vedantham, M.D., who will lead the trial. "By funding this study, the NHLBI has clearly recognized the strong potential of interventional radiology clot removal treatments for DVT to improve public health," added the associate professor at the Washington University School of Medicine's Mallinckrodt Institute of Radiology in St. Louis, Mo.
