Abstract
Purpose:
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.
Conclusion:
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.
