Objective
In this study, the evaluation of the mean values in the NT measurements of low-risk Turkish population is aimed. Also, the effect of gestational week, crown-rump length (CRL), parity and maternal weight on NT measurements is evaluated.
Methods
Between March 2013 and June 2014, 351 singleton pregnancies, who admitted to perinatology outpatient clinic for 11-14 week screening, are included in the study. NT, CRL measurements, gestational week, maternal weight, parity characteristics are analysed. 351 subjects are divided into 4 groups according to the CRL measurements: Group I for CRL 45-54 mm (n=62); Group II for CRL 55-64 mm (n=133); Group III for CRL 65-74 mm (n=115) and Group IV for CRL 75-84 mm (n=41). The groups are compared according to maternal age and NT measurements.
Results
The mean maternal age was 28.76 ± 5.51, gestational week was 12.29 ± 0.69, CRL measurements were 63.69 ± 9.07 mm, mean NT values were 1.23 ± 0.48 mm. There was no significant difference regarding the maternal age and NT measurements (p=0.817 and 0.072 respectively). NT values were significantly correlated with CRL (r=0.232; p=0.001) and gestational week (r=0.203; p=0.001). There was no relation between NT and gravida, parity and maternal weight.
Conclusion
First trimester screening has been commonly used in prenatal medicine. NT is a part of first trimester screening. NT measurement must be performed according to the stanrdardised measurement techniques. The management of the results should be organised according to the algorithms.
