The Importance of Monophasic Doppler Waveforms in the Common ...

Lin et al
compared with thigh DVT. It should also be recognized
that the incidence of iliac vein thrombosis
is likely higher than previously thought. In
light of these findings, we recommend routine
evaluation of external iliac veins in the presence
of monophasic waveforms and additional
imaging, if necessary, to determine the cause of
monophasic waveforms.
