摘要: To evaluate the value of pre-stenting and early post-stenting (<1 mo) duplex ultrasound parameters in predicting significant in-stent restenosis (ISR), we matched ISR patients 1:1 with controls without periods, respectively, using propensity score matching. Duplex parameters, such as renal length difference between non-lesion side lesion within patient, trans-lesion peak systolic velocity aortic ratio, were compared cases controls, area under receiver operating characteristic curve (AUROC) was charted to predict ISR. After matching, 28 period 16 time period. Pre-stenting difference, ratio showed differences case-control comparisons. Early (AUROC: 0.826, cutoff: 141 cm/s) 0.770, 1.75) performed well may serve non-invasive markers surveillance.
