Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis (DVT) Deep vein thrombosis (DVT) is a serious condition in which a thrombus, or blood clot, develops within a deep vein, usually in a leg. These clots can travel through the bloodstream to the brain, heart or lungs, potentially causing a life-threatening event. DVT affects approximately 300,000 adults per year, approximately half of whom have no symptoms.
