    Journal: Rofo; 1996 Jan; 164(1):38-41. PubMed ID: 8630358.
    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.
