[Color-coded duplex sonography (angiodynography) in the evaluation of arteriovenous shunts].
In 21 hemodialysis patients colour coded duplex sonography (angiodynography) was performed on 23 av-fistulae. In all patients topographic shunt pathways could be evaluated sufficiently, which corresponded well to digital subtraction angiography, that was available in a number of cases. Pathology could be easily identified by morphologic tissue changes in combination with altered flow patterns. The advantage of angiodynography in av-fistulae is a combined information about both morphology and flow dynamics, which can be won in an absolutely noninvasive manner.
