Comment on Doppler Ultrasound in Vascular Access care: The pearls and pitfalls of flow volume measurements
2020
Abstract
We have read the recent review of Diniz and Coentrão1 entitled "Doppler Ultrasound in Vascular Access care: the pearls and pitfalls of flow volume measurements'' with a great interest. The authors mention that Doppler ultrasound (DUS) is an operator dependent technique that needs substantial time of learning.
This ultrasound learning curve will probably not be longer than for any other imaging method. The problem rather is that ultrasound looks (too) easy.
Studies proving that DUS is reliable will be most applicable to situations where the examinations were performed by experienced (vascular) ultrasonographists.
