Abstract:
Objective To study the inconsistent relation of twin discordancy and the umbilical artery blood flow parameter of systolic/diastolic ratio.Methods 358 pregnant women were divided into the two groups of develop-mental nonidentity( n=67 ) and developmental identity ( n=291 ) according to the criterion that the differences of twins weight exceeded 25 percent.The umbilical artery blood flow parameter of systolic/diastolic ratio were observed. Meanwhile,the difference of weight and the umbilical artery blood flow parameter of systolic/diastolic ratio in the group of developmental nonidentity were observed.Results A significant difference of the umbilical artery blood flow parameter of systolic/diastolic ratio were found in the two groups of developmental nonidentity and developmental identity(7.81%vs 32.56%,P<0.05).There were 56 cases that twins weight exceeded from 25 to 35 percent,7 cases that twins weight exceeded from 35 to 45 percent and 4 cases that twins weight exceeded 45 percent in the group of developmental nonidentity which the umbilical artery blood flow parameter of systolic/diastolic ratio were (23.66 ± 5.78)%,(27.16 ±7.25)% and (33.16 ±4.23)% correspondingly with significant difference(F=23.21,P<0.05 ) .Conclusion The umbilical artery blood flow parameter of systolic/diastolic ratio has significance in diagnosis of twin discordancy.
