THE USEFULNESS OF INTRAVASCULAR ULTRASOUND IMAGING IN THE INTERVENTION THERAPY OF BLOOD ACCESS

Abstract

We applied intravascular ultrasound imaging (IVUS) to pre and post intervention therapy of blood access 9 timesfor 8 cases. After sumcient dilation was observed by angiography, IVUS was applied. The shapes that appeared-circular, Dharma, lacerated, confetti-suggested that they were not always sumciently dilated, IVUS isuseful not only in deciding the end point of interventional treatment but also in helping to investigate the cause of recurrence of vascular stenosis.
