The One

The aim of this study is to assess whether early cervical lymphatic obstruction is associated with a sonographically detectable dilatation of the ventricular system in the 1st trimester of pregnancy. In particular, the objective is to assess whether fetuses with non-immune hydrops fetalis (NIHF), cystic hygroma, or enlarged nuchal translucency (NT) have a greater atrial width/biparietal diameter (AW/BPD) ratio than normal at time of the combined first trimester screening scan. This retrospective study included 96 first trimester fetuses (33 normal and 63 with various degree of cervical lymphatic engorgement). Inclusion criteria were CRL in the 45-84 mm range and availability of one or more three-dimensional volume datasets of the fetal head, acquired from the BPD plane. Each three-dimensional volume dataset was opened and multiplanar correlation employed to align the three orthogonal planes. The ratio between the atrial width and the BPD (AW/BPD ratio) was used to evaluate the possible presence of increased amount of cerebrospinal fluid. Abnormal cases were placed into 4 categories: 1)enlarged non-septated NT 2.5-3.9 mm, no hydrops; 2) grossly enlarged non-septated NT/ edema >3.9 mm; 3) cystic hygroma and/or NIHF; 4) major anomalies with NT <2.5 mm. Presence of dilatation of the latero-cervical jugular lymphatic sacs, karyotype and presence of congenital anomalies were also recorded. The One-way ANOVA test was used to compare means. Intra- and inter-observer variability were also assessed. The AW/BPD ratio was found to be significantly higher in fetuses with grossly enlarged NT/nuchal edema and NIHF/septated cystic hygroma than in normal (p <0.05 and p <0.01, respectively). Also, the AW/BPD ratio was significantly higher in NIHF/septated cystic hygroma than in enlarged NT 2.5-3.9 mm (p <0.05). In case of enlarged NT (2.5-3.9 mm), the AW/BPD ratio is significantly higher in presence of JLS (p <0.01). At the end of the first trimester, presence of cervical lymphatic engorgement, in terms of grossly enlarged NT, nuchaledema, septated cystic hygroma, and NIHF, is statistically associated with a moderate dilatation of the ventricular system. Of note, among fetuses with moderately enlarged NT, those with evidence of dilatation of the JLS show a statistically significant increase in the AW/BPD ratio.

Diagnostic Criterion

Objective: to identify the most effective and affordable method to diagnose various types of fetal cleft lip and palate, the use of which is possible in the majority of specialized obstetric care facilities. Material and methods. The study included the results of ultrasound examination of fetuses (59 cases) in various modes with cleft lip and palate of various types within gestational periods from 16 to 36 weeks. Results. The sensitivity indices of the generally accepted method of two-dimensional B-mode ultrasound have been determined for diagnosing all types of clefts, which amounted to 81.3 %, and the sensitivity for diagnosing cleft palate and cleft lip and palate amounted to 80.3 %. The sensitivity indices of the newly developed diagnostic method (ultrasound elastography of the palate) have been determined, which amounted to 89.8 % in the diagnosis of all types of clefts, and 90.2 % in the diagnosis of cleft palate and cleft lip and palate (46/51). Demonstration of the image of the fetal face obtained during the three-dimensional B-mode reconstruction to its future parents helps the family to make a more balanced and correct decision on further pregnancy tactics. In cases of cleft palate, a new visualization diagnostic criterion has been defined - tongue bifurcation. MRI of the fetal head is not an effective and affordable method for the diagnosis of facial clefts, which can be widely used in practice. Conclusion: It is advisable and necessary to conduct an obligatory study of the karyotype in fetuses with crevices identified during imaging examination at any gestational age. As a new diagnostic criterion for cleft palate, detected by B-mode ultrasound, tongue bifurcation can be used. The utilization of the EN method in combination with the developed coloristic criteria for RHN and RN increases their prenatal detection in general population by 9.9 %. At the same time, the detectability of all types of crevices increases by 8.5 %. In order to objectify the explanations about the essence of revealed defects of the face and structures of the oral cavity, it is necessary to demonstrate a three-dimensional sonogram of the fetal face obtained during three-dimensional B-mode reconstruction to its future parents. MRI of the fetal head cannot be recommended as an effective and affordable method for diagnosing facial clefts due to the impossibility to obtain a satisfactory image in most cases.
