Conclusion: We have established comprehensive reference ranges for first-trimester BPD and FL by sonography which may allow to the correct dating and pregnancy follow-up.

🎯
Objective & Hypothesis:Objective: To establish reference ranges for fetal size by gestation in the first trimester as indicated by cephalic and limb measurements according to CRL, using transvaginal sonography in normal pregnancies.

Abstract

Objective: To establish reference ranges for fetal size by gestation in the first trimester as indicated by cephalic and limb measurements according to CRL, using transvaginal sonography in normal pregnancies. Methods: Transvaginal measurements of biparietal diameter (BPD) and Femur length (FL) were prospectively collected from 394 structurally and or chromosomally normal singleton fetuses representing for 11-14 week screening (CRL: 45-84 mm). Reference ranges were constructed and the mean, 5th, and 95th centiles were plotted against gestation using regression analysis method. Results: Measurements of BPD, and FL were significantly correlated with CRL. Regression correlation was BPD= 3.2956+0.2897xCRL, r=0.8885, p<0.001, for BPD and, FL= -5.2381+0.2100xCRL, r=0.8336, p<0.001 for FL. Conclusion: We have established comprehensive reference ranges for first-trimester BPD and FL by sonography which may allow to the correct dating and pregnancy follow-up.

Özet

Amaç: Prognozu bilinen normal gebeliklerde 11-14. gebelik haftalarında CRL'ye (baş makat mesafesi) göre, biparyetal çap (BPD) ve femur uzunluğu (FL) nomogramlarının elde edilmesi. Yöntem: 11-14 hafta (CRL 45-84 mm) taraması için başvuran gebelerde, yapısal veya kromozomal olarak normal 394 fetusa ait biyometrik ölçümler transvaginal yoldan yapılarak, elde edilen BPD ve FL değerlerinin ortalama, 5. ve 95. persentil değerleri ile nomogramları regresyon analiz yöntemi ile oluşturuldu. Bulgular: Ölçümü yapılan fetal biyometrik parametrelerin CRL ile yüksek korelasyon gösterdiği izlendi. CRL ile BPD arasındaki regresyon denklemi: BPD= 3.2956+0.2897xCRL, r=0.8885, p<0.001, femur uzunluğu arasındaki regresyon denklemi: FL=-5.2381+0.2100xCRL, r=0.8336, p<0.001 olarak saptandı. Sonuç: 11-14. hafta düşük risk grubundan elde edilen fetusa ait BPD ve FL uzunluğuna ait nomogramlar, kendi toplumumuzda gebelik haftasının doğru saptanması ve fetal gelişimin izlenmesi için oluşturuldu.
