Abstract:
Objective To discuss the value of minimum systolic and diastolic peak velocity ratio(S/D) and pulse index(PI) of the umbilical artery of pregnant twins in predicting perinatal outcome.Methods Pulsed Doppler measurements of the umbilical artery were conducted in 77 cases of twin pregnancise. Perinatal outcome was compared between normal and abnormal umbilical artery S/D,PI group respectively. The rates of abnormal umbilical artery S/D,PI in monochorionic and dichorionicdich were compared. Results The rates of adverse perinatal outcome,small for gestational age(SGA),structural malformation in abnormal umbilical artery S/D group were significantly higher than those in normal umbilical artery S/D group ( P
