[Initial experiences with dilatation of dialysis shunts with color-coded duplex ultrasonography monitoring].
OBJECTIVE
Aim of the study was to evaluate the technical aspects of colour coded duplex sonography guided interventions of peripheral vessels.


METHODS
During 15 months 39 stenoses of shunt veins in 24 patients were dilated guided by colour coded duplex sonography.


RESULTS
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.


CONCLUSIONS
PTA guided by colour coded duplex sonography is an alternative to DSA guided interventions of superficial vessels without x-ray exposure or contrast agent application.
