Ambulatory venous pressure (AVP) monitoring is the criterion standard in assessing the hemodynamics of CVI. This test involves the insertion of a needle connected to a pressure transducer into the dorsal foot vein. It has been shown to be valuable in assessing the severity and clinical outcomes of CVI. Its use is limited given its invasive nature, possible limitations, and potential alternate diagnostic modalities. [21]
