For the formation of a venous thrombosis in the IVC (inferior vena cava) stenosis model, a reduction of the original flow by approximately 80% is necessary. In Fig. 5, the average pulsed-wave Doppler flow velocity (mm/s) in the vena cava before and after stenosis of the vessel is shown. (Adapted from [3]; with kind permission from IOS, Amsterdam)
