Doppler ultrasound scan of a patient's leg, showing deep vein thrombosis (DVT). The vein, showing as dark area can be seen to have a (lighter-coloured) clot in the centre, which carries the risk that it will break away and be carried in the bloodstream to the brain, heart or lungs with fatal results, through stroke, thrombosis or pulmonary embolisms.
