<b><i>Purpose:</i></b> The objective of this study was to estimate the accuracy of 22 fetal weight estimation formulas in diabetic pregnancies uncomplicated and complicated by fetal macrosomia. <b><i>Methods:</i></b> Retrospectively collected data of 317 pregnancies complicated by gestational diabetes mellitus and 78 cases of fetal macrosomia were used in this study. Study inclusion criteria were women diagnosed with gestational diabetes mellitus, full-term singleton pregnancy, and an interval from the ultrasound to delivery of ≤7 days. The estimated fetal weight was calculated using 22 formulas. The mean absolute percentage error (MAPE) and two-way random interclass correlation coefficient were chosen for statistical analysis. <b><i>Results:</i></b> In the group of gestational diabetes, MAPE ranged from 8.43 ± 10.17 to 54.01 ± 9.50%. Most of the formulas showed a tendency to estimate a lower fetal weight in comparison to the actual birth weight. In the group of fetal macrosomia, the correlations were poor. Only three formulas reached the threshold of MAPE &#x3c;10%. <b><i>Conclusions:</i></b> The formula by Hsieh might be considered the best for fetal weight estimation in diabetic pregnancies. The combination of the best formulas might improve the accuracy of estimation. None of the formulas were accurate enough to predict fetal macrosomia.

Background. Mother’s attachment to her unborn child has a strong impact on a pregnant woman’s attitude towards her health, postnatal attachment, and the child’s physical and emotional growth. The purpose of our study was to identify the factors that impact the maternal-foetal relationship. Materials and methods. The study was conducted at the Centre of Obstetrics and Gynaecology of the tertiary-level Vilnius University Hospital Santaros Klinikos in Vilnius, Lithuania. An original questionnaire of nine parts was developed that the questionnaire included information on demographical data, gynaecological and obstetrical history, a relationship assessment scale, the index of happiness, an antenatal depression risk questionnaire, and the Maternal-Antenatal Attachment Scale. Results. The study included 388 pregnant women. It was found that the level of education, obstetrical issues during pregnancy, and the risk of postnatal depression negatively impacted the maternal-foetal relationship (p < 0.05). Mothers who were elder in family birth order, also those whose pregnancy was of a longer duration, who had a better-quality romantic relationship with partner, and whose socioeconomic fulfilment was higher were all found to have a better quality of maternal-foetal bonding (p < 0.05). Conclusions. The early recognition of low attachment and right application of various means of psychologic intervention might improve the quality of pregnancy, maternity, and childhood.

Background.Placenta percreta is a very rare, but extremely life-threatening obstetrical pathology for the mother and the child, especially in the cases when it is not diagnosed before the birth and when it results in massive bleeding and a dramatic deterioration of condition. It is extremely important to diagnose this pathology as early as possible and plan further optimal care of patients in order to minimize life-threatening complications.Case report.The paper presents an illustrated clinical case of placenta percreta determined before the birth. Features of visual diagnostics are discussed.A 32-year-old pregnant woman with a history of two caesarean deliveries arrived at the tertiary level hospital at 22 weeks of gestation due to abdomen pain. Placenta previa was diagnosed and ultrasound, magnetic resonance imaging suggesting placenta percreta were seen. On the 32nd week, the planned caesarean hysterectomy was performed. The balloon catheters to occlude the internal iliac arteries and minimize bleeding during the surgery were used.Conclusions.Antenatal diagnosis of placenta percreta is especially important. Methods of visual diagnostics are complementary. The optimal surgical approach during caesarean hysterectomy remains controversial. In the case of the slow oozing without a clearly identified source of bleeding after hysterectomy and internal iliac arteries balloons deflation, ligation of one of the internal iliac arteriescan be reasonable to avoid residual haemorrhage and relaparotomy.
