Duplex ultrasound investigation of the veins in chronic venous disease of the lower limbs – UIP Consensus Document. Part I: Basic principles

摘要

Objectives: Duplex ultrasound investigation has become the reference standard in assessing the morphology and haemodynamics of the lower limb veins. The project described in this paper was an initiative of the Union Internationale de Phlébologie (UIP). The aim was to obtain a consensus of international experts on the methodology to be used for assessment of veins in the lower limb by ultrasound imaging.
