Abstract: Objective To study the diagnostic values of S/D and △Q of umbilical artery (UmA), bilateral uterine arteries (UtA), and internal iliac artery (IlA) in maternal circulation on prediction of perinatal outcome in patients with pregnancy-induced hypertension (PIH). Methods Dopple ultrasound screening was used to detect the S/D and △Q of UmA, UtA and IlA in 48 patients with PIH and 62 cases of normal singleton pregnancy. Results The sensitivity (82.1%), likehood ratio (4.49), and Youden′s index (0.638) of UmA S/D were higher than those of UtA S/D;the sensitivtity (85.7%), specificity (82.9%), likehood ratio (5.01), and Youden′s index (0.686) of UmA △Q were all higher than those of UtA △Q; and the various indexes of UmA △Q and UtA △Q were higher than those of UmA S/D and UtA S/D; each index of IlA S/D and IlA △Q was lower. Conclusion The diagnostic value of △Q for perinatal outcome in patients with PIH is superior to S/D; the diagnostic values of IlA S/D and IlA △Q are lower than those of UmA and UtA.
