Prenatal diagnosis and outcome of congenital dacryocystoceles.

Objective: To determine the incidence and present our experience with prenatal diagnosis and postnatal outcome of dacryocystocele.

Material And Methods: All cases of congenital dacryocystocele diagnosed in our center between 2020 and 2022 were identified in our database to establish the incidence of these defects. The medical records were then reviewed for gestational age, gender, size, and side of dacryocystocele and postnatal outcome.

A new two-dimensional sonographic approach to the assessment of the fetal hard and soft palates.

Facial clefts are among the most common congenital defects. Ultrasound (US) imaging of secondary fetal palate, especially the detection of isolated defects, remains challenging. Currently described two-dimensional (2D) and three-dimensional methods are technically demanding and impractical for application during routine fetal anatomy evaluation.

Impact of 3D ultrasound on fetal CNS examination.

Objective: An overview of current knowledge about the use of 3D ultrasound examinations for the examination of fetal CNS.

Design: A review article.

Setting: Department of Gynecology and Obstetrics, Faculty of Medicine and Dentistry, Palacký University and Faculty Hospital Olomouc.

Prenatal diagnosis of Pallister-Killian syndrome in pregnancy with normal CVS result and abnormal ultrasound findings in the second trimester.

Objective: To highlight importance of detailed ultrasound examination in fetuses with known normal karyotype (and micro-array result) from CVS. In case of markedly abnormal ultrasound result repeated karyotyping by amniocentesis should be considered. Sample should be analyzed by routine cytogenetic techniques, however also micro-array and targeted FISH should be added in order to achieve most accurate diagnosis.

3-D Volume Assessment of the Corpus Callosum and Cerebellar Vermis Using Various Volume Acquisition and Post-Processing Protocols.

Objectives: To determine which 3-D techniques are most effective for "real time" prenatal ultrasound assessment of the corpus callosum and cerebellar vermis.

Methods: A prospective study involving 100 consecutive normal singleton pregnancies attending routine anomaly scan at 19-23 weeks' gestation. Midsagittal structures of the fetal brain were assessed using six different methods of 3-D image acquisition and three post-processing techniques.
