Non-invasive evaluation of proximal vertebral artery stenosis using color Doppler sonography and CT angiography

Popis výsledku v původním jazyce

Background and purpose A reliable and safe diagnostic procedure for vertebral artery (VA) stenosis is needed, but none is generally accepted yet. In our study, we evaluated symptomatic VA stenoses using color Doppler sonography (CDS). CT angiography (CTA) has been employed as a non-invasive reference method. Next, we tested the accuracy for medium to high degree stenoses by digital subtraction angiography (DSA). Materials and methods Sixty-two symptomatic patients with a proximal VA stenosis were examined prospectively with CDS and CTA. The VA diameters by both methods were correlated. The stenotic peak systolic velocity (PSV1) and its ratio to the post-stenotic segment (PSVr) were analysed using receiver operating characteristic curve (ROC). Cut-off values for PSV1 and PSVr defining moderate and severe stenosis were assessed. In stenoses >= 50%, an additional search for correlation with DSA was carried out. Results Mean VA diameter was 3.561 mm (95% CI 3.361?3.760) by CDS and 4.180 (9
