Basic scanning method for vascular access ultrasound

Abstract

Evaluation of vascular access ultrasound has been used for a long time. Vascular access ultrasound is described as an objective evaluation method of peripheral circulation disorders in the guideline published by the Japanese Society of Dialysis Therapy1). In vascular access ultrasound, B-mode images provide detailed tomographic images of the intima, the blood vessel wall, and the surrounding tissue, and the color Doppler method and pulse Doppler method can measure blood flow direction, blood flow velocity, and blood flow volume. Vascular access ultrasound is a minimally invasive examination method that can be used to evaluate the configuration and function of vascular access. This chapter, which focuses on arteriovenous fistula (AVF) and arteriovenous graft (AVG), describes the basic scanning method for vascular access ultrasound.
