Postprocedural Peak Systolic Blood Flow Measurements Correlate with the Need for Stent Reintervention at 12 Months

PSF from an initial postprocedure duplex study accurately correlates with need for repeat stent intervention at 12 months. PSV had a lower sensitivity, specificity, and accuracy. This preliminary finding must be confirmed by prospective studies in individual vascular beds and larger patient populations. A new approach to stent surveillance is suggested.
