Lower uterine segment thickness measurement in pregnant women with previous Cesarean section: reliability analysis using two- and three-dimensional transabdominal and transvaginal ultrasound

To evaluate the reliability of two‐ and three‐dimensional ultrasonographic measurement of the thickness of the lower uterine segment (LUS) in pregnant women by transvaginal and transabdominal approaches.

Antenatal diagnosis of unilateral congenital cystic adenomatoid malformation associated with Taussig-Bing syndrome: case report

Aims: To report a rare case of antenatal diagnosis of unilateral congenital cystic adenomatoid malformation associated with Taussig-Bing syndrome. Case description: Patient aged 40 years, four pregnancies with three previous vaginal deliveries, black skin, married, housewife, without prior conditions, was referred to the Fetal Medicine Unit of the University Hospital of Santa Maria due to changes in the thoracic region of the fetus found in routine obstetric ultrasound examination performed at 30 weeks and three days of gestation. At the Doppler ultrasound assessment performed in the reference center, perimembranous ventricular septal defect and transposition of the great vessels were found, characterizing the Taussig-Bing syndrome. Additionally, a unilateral pulmonary congenital cystic adenomatoid malformation type 2 was found. The medical staff decided by a cesarean delivery in a referral center for cardiology, with 37 weeks of gestation. The neonate, weighing 3 kg, presented since the first hours acute respiratory distress with severe cyanosis, and underwent lobectomy. The neonate died within two weeks of life due to respiratory failure during the performance of a surgical procedure to correct the cardiac malformation. Conclusions: There is no description in the literature of association between Taussig-Bing syndrome and congenital cystic adenomatoid malformation. Early ultrasound diagnosis and monitoring in a Fetal Medicine unit is important for planning pre and post-natal interventions and family counseling by a multiprofessional team.

Sensibilidade e especificidade da oximetria fetal de pulso e da cardiotocografia durante o parto: comparação entre os métodos no prognóstico de recém-nascidos Acidóticos

Purpose: to study the sensitivity and specificity based on fetal oxygen saturation (SpO2) values and fetal heart rate (FHR) patterns during labor, for the prognosis of acidotic fetuses at birth. Patients and Methods: SpO2 values were obtained by fetal pulse oximetry technique. A fetal SpO2 value ³30% was considered normal, and an SpO2 which remained <30.0% for more than 10 min between contractions was considered abnormal. Fetal SpO2 and FHR tracings were obtained during the first and second stage of labor. FHR classification used in the study has been derived from the National Institute of Child Health and Human Development19. Results: a total of 72 subjects were studied. The sensitivity and specificity, based on SpO2, were 61.5% and 96.6%, respectively, whereas the sensitivity and specificity based on FHR patterns were 69.2% and 66.1%. Positive and negative predictive values based on SpO2 were 80% and 91.9%, respectively, and based on FHR patterns were 31% and 90.7%, respectively. Conclusions: a good fetal SpO2 specificity for prognosis of acidotic fetuses at birth was found, if compared with FHR pattern specificity, whereas sensitivity was poor for both methods. However, the number of acidotic fetuses was too small to allow more conclusions
