Abstract:
OBJECTIVE:To explore the value of ultrasonographic evaluation in fetal deformity in prenatal diagnosis by a systematic continuous sequence approach (SCSA).
METHODS:Successive prenatal ultrasonographic evaluation was performed to monitor the whole anatomic structure,form, posture and movement of 16,685 fetuses during gestation aging 14 approximately 40(+3) weeks.
RESULTS:Satisfactory ultrasonic images were obtained in 16,627 fetuses using the SCSA (99.65%). Of them, 514 abnormal fetuses were confirmed after subsequent labor or induced labor and 498 abnormal fetuses were correctly diagnosed using SCSA during prenatal stage (96.89%). Whereas 16 fetuses missed recognition (3.11%). Its sensitivity, specificity, positive and negative predictive value of diagnosis on fetal deformity were 96.98%, 99.96%, 98.66%, and 99.90 %, respectively.
CONCLUSION:SCSA in prenatal ultrasonographic evaluation of the fetal structure and malformation is reliable and accurate.
