First-Trimester Ultrasound Imaging for Prenatal Assessment of the Extended Cardiovascular System Using the Cardiovascular System Sonographic Evaluation Algorithm (CASSEAL).

Introduction And Objectives: To compare fetal images obtained at the first- and second-trimester ultrasound scan when applying the Cardiovascular System Sonographic Evaluation Algorithm (CASSEAL).

Methods: Using the CASSEAL protocol, nine sequential axial views were acquired in B-mode and color Doppler at the first- and second-trimester ultrasound scans, visualizing the main components of the extended fetal cardiovascular system. Images were compared qualitatively between both trimesters.

Uterine Artery Embolization of Uterine Arteriovenous Malformation: A Systematic Review of Success Rate, Complications, and Posterior Pregnancy Outcomes.

Uterine Arteriovenous Malformation (UAVM) is a rare but life-threating cause of uterine bleeding. The clinical management of this condition is challenging, and there is a need to describe the most adequate approach for these patients. Uterine artery embolization (UAE) is the most widely-published treatment in the literature in recent years, although there is a need to update the evidence on this treatment and to compare it with other available therapies.

Patients with Invasive Lobular Carcinoma Show a Significant Increase in IRS-4 Expression Compared to Infiltrative Ductal Carcinoma-A Histopathological Study.

Breast cancer (BC) is the first diagnosed type of cancer and the second leading cause of cancer-related mortality in women. In addition, despite the improvement in treatment and survival in these patients, the global prevalence and incidence of this cancer are rising, and its mortality may be different according to the histological subtype. Invasive lobular carcinoma (ILC) is less common but entails a poorer prognosis than infiltrative ductal carcinoma (IDC), exhibiting a different clinical and histopathological profile.

Effects of Sex, Age and Height on Symphysis-Ischial Spine Distance Measured on a Pelvic CT.

Objective: To examine the influence of age, sex and height on the symphysis-ischial spine distance (SID) measured on pelvic Computed tomography (CT)images in subjects of reproductive age, and to determine the interobserver reproducibility. This measurement (SID) is of great importance because the use of intrapartum ultrasound is based on the assumption of a specific value (30 mm) of such a measurement.

Methods: This was a cross-sectional descriptive study in which SID was measured in subjects aged 20 to 44 years who had been scheduled for pelvic CT at our centre from January 2018 to May 2021 for different reasons.

Maternal, Perinatal and Neonatal Outcomes of Triplet Pregnancies According to Chorionicity: A Systematic Review of the Literature and Meta-Analysis.

Triplet pregnancies are rare events that affect approximately 93 in 100,000 deliveries in the world, especially due to the increased use of assisted reproductive techniques and older maternal age. Triplet pregnancies are associated with a higher risk of fetal and maternal morbidity and mortality compared to twins and singletons. Chorionicity has been proposed as a major determinant of perinatal and maternal outcomes in triplet pregnancies, although further evidence is needed to clarify the extent and real influence of this factor.

Workshop on Blood Loss Quantification in Obstetrics: Improving Medical Student Learning through Clinical Simulation.

Purpose: To assess whether a clinical simulation-based obstetric blood loss quantification workshop for medical undergraduate trainees improves theoretical-practical knowledge, along with self-assurance and self-confidence.

Methods: This was a quasi-experimental pre-post learning study conducted at the Gynaecology and Obstetrics Unit of the Hospital Gregorio Marañón, Madrid, Spain. Participants were volunteer students in their fourth year of a 6-year degree course in Medicine.

Maternal-Perinatal Variables in Patients with Severe Preeclampsia Who Develop Acute Kidney Injury.

At present, we are witnessing an increase in preeclampsia, especially the most severe forms, which are associated with an increased risk of maternal-perinatal morbidity and mortality. As a severity criterion, acute kidney injury (AKI) has been associated with a worse prognosis, and for this reason, the maternal and perinatal variables associated with AKI in patients with severe preeclampsia (SP) were analysed in this study. An observational, retrospective, single-centre study of patients with SP treated at a tertiary hospital between January 2007 and December 2018 was conducted.

Comparing Infection Profiles of Expectant Mothers with COVID-19 and Impacts on Maternal and Perinatal Outcomes between the First Two Waves of the Pandemic.

During 2020, Coronavirus Disease-19 (COVID-19) incidence fluctuated in two clear waves across the spring and autumn periods. This study was designed to compare the maternal and perinatal clinical outcomes in obstetrics patients with COVID-19 between the two waves of infection in Spain. We conducted an observational, analytical, ambispective cohort study with longitudinal follow-up of mothers with confirmed SARV-CoV-2 infection from different hospitals in our country between March-November 2020.

Factors Associated with Failure of Bakri Balloon Tamponade for the Management of Postpartum Haemorrhage. Case Series Study and Systematic Review.

Background: Postpartum haemorrhage (PPH) is an unpredictable obstetric emergency that requires a multidisciplinary approach. Bakri balloon tamponade (BBT) is recommended when PPH does not respond to medical treatment. Nowadays few published studies have performed a multivariate analysis to determine the variables independently associated with BBT failure.

[Ultrasound scan of the fetal thymus].

There is an increased interest nowadays on ultrasound analysis of the fetal thymus. Abnormal fetal thymic growth have been associated with DiGeorge syndrome, conotruncal cardiac malformations, chromosomal abnormalities and adverse outcome in different perinatal conditions as intrauterine growth restriction, preterm birth and others. Different methodologies that measure the fetal thymus by ultrasound have been published, however there is not a consensus of which one is the most useful.

[Perinatal outcome after prenatal diagnosis of intra-abdominal umbilical vein varix].

Background: Increased number of cardiovascular disorders diagnosed prenatally is not a consequence of a spontaneous growing, but of the advance in echographic techniques, specifically, high-resolution echography, color Doppler, a higher knowledge and systematization in exploring fetal anatomy.

Objective: To describe the sonographic findings and perinatal outcomes in cases with prenatal ultrasound diagnosis of intraabdominal umbilical vein varix (UVV).

Methods: Retrospective study of cases with prenatal ultrasound diagnosis of UVV.

[Perinatal outcome after prenatal diagnosis of intra-abdominal umbilical vein varix].

Background: Progress in echographic techniques, particularly, high-resolution echography and color Doppler, as well the higher deep on knowledge and systematization in fetal anatomy exploration, are the main responsible of the increased number of cardiovascular anomalies diagnosed prenatally.

Objective: To describe the sonographic findings and perinatal outcomes in cases with prenatal ultrasound diagnosis of intra-abdominal umbilical vein varix.

Material And Methods: A descriptive and retrospective study of cases with prenatal ultrasound diagnosis of umbilical vein varix.

[Diagnosis of isolated fetal aberrant right subclavian artery].

Unlabelled: A case of a fetal isolated aberrant right subclavian artery (ARSA) diagnosis and discuss its clinical implications and the methodology used to assess the fetal right subclavian artery by transabdominal ultrasound in normal cases and those with ARSA is reported.

Clinical Case: A 35-year-old pregnant woman in her twentieth week of pregnancy was evaluated at our Fetal Medicine Unit. An isolated ARSA was detected by a transabdominal ultrasound scan of the fetus.
