| Popis: | Objective. The aim of the study was to assess the potential of 3-dimensional (3D) color-coded duplex sonography (CDS) for evaluation of the vertebral artery origin and stenoses in this location. Methods. To compare 2-dimensional (2D) and 3D CDS, both techniques were performed in 25 healthy volunteers and in 18 patients with 21 stenoses of the vertebral artery origin. Stenoses were graded in line with hemodynamic criteria on 2D CDS and according to North American Symptomatic Carotid Endarterectomy Trial criteria on 3D CDS. In 6 patients, digital subtraction angiography (DSA) was performed additionally. Stenoses were graded according to North American Symptomatic Carotid Endarterectomy Trial criteria and compared with 2D and 3D sonographic data. Results. Overall correlation of both sonographic techniques concerning the grading of the stenoses was good (r = 0.69; P |
