New blood thinner beats older drug for vein clots

(HealthDay)—People who need to take a blood thinner because they've had a clot in the deep veins of their legs appear to do better with the new drug Pradaxa (dibigatran) than with the older drug warfarin, researchers report.

A thrombus (Greek θρόμβος), or blood clot, is the final product of the blood coagulation step in hemostasis. It is achieved via the aggregation of platelets that form a platelet plug, and the activation of the humoral coagulation system (i.e. clotting factors). A thrombus is normal in cases of injury, but pathologic in instances of thrombosis.

Mural thrombi are thrombi adherent to the vessel wall. They are not occlusive and affect large vessels, such as heart and aorta. Grossly they appear grey-red with alternating light and dark lines (lines of Zahn) which represent bands of fibrin (darker) with entrapped white blood cells and red blood cells (lighter).
