The month of October is now recognized in Illinois as Thrombosis Awareness Month, thanks to legislation sponsored by Senator Pamela Althoff (R-McHenry) and adopted by the Senate earlier this year. Approximately 600,000 people in the United States are estimated to develop venous thromboemoism, and 400,000 expected to develop deep vein thrombosis of the legs. Pulmonary emoblisms, a serious and potentially fatal complication of vein thrombosis affects at least 200,000 people in the nation per year.
