Purpose: our aim was to evaluate the usefulness and limitations of ultrasound (US) examination following stenting for supraaortic artery stenosis. Methods: Twenty-four patients were examined; 9 had stenosis of the carotid artery bifurcation, 8 had stenosis of the proximal portion of the vertebral artery, and 7 had stenosis of the subclavian artery. US examinations were performed by B-mode and pulsed Doppler before and immediately after stenting, and every 3 months thereafter. Digital subtraction angiography (DSA) was performed immediately after and 6 months after stenting. Results: For carotid artery stenting, we were able to evaluate morphological patency by B-mode (84% of cases), and hemodynamics by pulsed Doppler in the stented portion. These data were confirmed by DSA.
