['Aim of the study was to evaluate the technical aspects of colour coded duplex sonography guided interventions of peripheral vessels.', 'During 15 months 39 stenoses of shunt veins in 24 patients were dilated guided by colour coded duplex sonography.', '38 stenoses were dilated without complications. The blood flow volume was increased from 361.9 +/- 83.5 to 718.9 +/- 189.2 ml/min. In one case it was not possible to dilate the stenosis because of a vasospasm.'] Does [ Initial experiences with dilatation of dialysis shunt with color-coded duplex ultrasonography monitoring ]?
