Objective:
To create a reference centile chart for fetal liver length of Thai fetuses.
Design:
Prospective, cross-sectional study.
Setting:
Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University.
Material And Method:
A total of 752 pregnant women, who attended the antenatal clinic at Siriraj Hospital, Mahidol University, Bangkok, were recruited between 13-40 weeks of gestation. Each fetus was measured only once for the purpose of this study. Using real-time ultrasound with a 3.5 MHz convex transducer; the authors measured fetal liver length. The mean and standard deviation (SD) were estimated at each week of gestation using linear regression modeling.
Results:
A total of 750 fetuses were measured for fetal liver length. Linear regression models were fitted to estimate the mean and 95% confidence interval for liver length at each gestation age. The centile chart of liver length was also presented
Conclusion:
A reference centile chart for fetal liver length of Thai fetuses has been created.
