Comparison of 3 Ultrasonic Techniques for Measuring the Systolic Pressure Index

University Hospital, Caen150 enrolled

Overview

Continuous Doppler ankle brachial index (ABI) is the gold standard for screening and monitoring of peripheral arterial disease (PAD) but is no longer carried out in clinical practice. The recommended measurement was gradually replaced by colour or pulsed Doppler without validation of these techniques. The objective of our study is to compare these two techniques (color Doppler and pulsed Doppler in echodoppler) with respect to the gold standard (continuous Doppler) for ABI measurement.
