ABSTRACT The use of three-dimensional (3D) ultrasonography since the first trimester of pregnancy allows the diagnosis and follow-up of cord entanglement throughout the entire pregnancy and delivery. This technology permits a more accurate diagnosis when compared with two-dimensional (2D) ultrasonography or Doppler The vast majority of cord entanglements observed at the end of the first-trimester will persist during the entire pregnancy; delivery outcome is usually not affected by this finding except for cases in which multiple cord entanglement is diagnosed.

ABSTRACT The introduction of three-dimensional (3D)/four-dimensional (4D) sonography with high-frequency transvaginal transducer has resulted in remarkable progress in ultrasonographic visualization of early embryos and fetuses and development of new fields of 3D sonoembryology. With the proper use of this new diagnostic modality and with experienced examiner, both structural and functional development in the first trimester of gestation can be assessed more objectively and reliable. Indeed, new technology moved embryology from postmortem studies to the in vivo environment. Furthermore, there are good reasons to believe that 3D/4D sonography moved prenatal diagnosis of fetal abnormalities from the second to the first trimester of pregnancy. We will try to illustrate it with the number of convincing figures. How to cite this article Pooh RK, Kurjak A.

Abstract Objectives To establish a practical and valid method for the diagnosis of twin gestation in uteri with Müllerian anomalies in the first trimester of pregnancy. Case presentation This was a prospective cohort study. Two cases with congenital uterine anomalies were followed prospectively from 7 weeks of gestation and compared to eight controls. The longitudinal to transverse uterine lumen diameter ratio (LTDR) was measured in mid-sagittal and coronal planes. The LTDR was compared between unicornuate and didelphys uteri to normal uteri controls weekly. The area under the curve for the coronal and sagittal planes were 1.000 and 0.823, respectively. For the coronal plane, an LTDR of 1.15 was selected as optimal for predicting uteri with a Müllerian anomaly, with a sensitivity of 100%, specificity of 100%. An LTDR of 1.68 in the sagittal plane was selected as optimal for predicting anomalous uteri, with a sensitivity of 100%, specificity of 73%. Conclusions LTDR ratios measured in mid sagittal and coronal planes of unicornuate and didelphys uteri with twin gestation during the first trimester of pregnancy are highly predictive of Müllerian anomalies. Early diagnosis of uterine anomalies could provide a reference to initiate earlier meticulous follow-up.
