Diploid fetus with partially triploid placenta: case presentation and management strategy.

Multiple placental cysts are a common finding in obstetric ultrasound imaging. Although they have benign differential diagnoses, such as hydropic degeneration of the placenta or placental mesenchymal dysplasia, it's important to consider significant pathologies, such as benign gestational trophoblastic disease or hydatidiform mole. A challenging issue in obstetrics is pregnancies with a placenta that has a bipartite texture.

Fetal intracranial hemorrhage and infarct: Main sonographic and MRI characteristics: A review article.

Early detection of fetal intracranial hemorrhage and infarct during pregnancy is crucial for preventing lethal and debilitating complications in neonatal life. Every radiologist must be aware of the imaging features of these conditions to refer patients to specialists. Sonographic and MRI features of fetal intracranial hemorrhage and infarct have been discussed in many previous articles.

Severe fetal hemolytic disease due to anti-M alloimmunization: A case report and literature review.

Fetal hemolysis is caused by maternal antibodies that cross the placenta. Anti-M antibodies can rarely cause severe forms of alloimmunization in the fetus and newborn. We present a case of severe anti-M alloimmunization requiring a total of 8 intrauterine transfusions, in a patient with a prior poor obstetrical history.

Pregnancy outcomes of normal karyotype fetuses with increased nuchal translucency.

Background: Although the association between first-trimester increased nuchal translucency (NT) and chromosomal defects is well-defined, there is little knowledge about the importance of increased NT in fetuses with normal karyotypes. Hence, this study was designed to evaluate outcomes of normal karyotype fetuses with increased NT.

Methods: This observational retrospective study was conducted on 720 pregnancies with increased NT (>3mm) at 11 to 13 weeks of gestational age in Yas Hospital, Tehran, Iran, from 2016 to 2020.

Radiofrequency Ablation and Intrauterine Transfusion in a Delayed Diagnosed Acardiac Twin Pregnancy.

Twin reversed arterial perfusion (TRAP) sequence or acardiac twin is a rare and severe complication of monochorionic multiple pregnancies. Acardiac twin accounts for 10% of all TRAP sequences, which is the most morphologically developed acardius. We present an undiagnosed TRAP sequence case up to 24 weeks of gestation who underwent successful amnioreduction, radiofrequency ablation (RFA), and intrauterine transfusion (IUT).

Materials And Methods: This prospective cohort study was conducted among pregnant women in the second trimester that were classified as having a high or low risk according to their prenatal aneuploidy screening outcome.

Relationship between fetal middle cerebral artery pulsatility index and cerebroplacental ratio with adverse neonatal outcomes in low-risk pregnancy candidates for elective cesarean section: A cross-sectional study.

Background: The cerebroplacental ratio (CPR) is an important factor for predicting adverse neonatal outcomes in appropriate-for-gestational-age fetuses.

Objective: To evaluate whether there is an association between the CPR level and adverse neonatal outcomes in appropriate-for-gestational-age fetuses.

Materials And Methods: This cross-sectional study included 150 low-risk pregnant women candidates for elective cesarean sections at the gestational age of 39 wk.

Postmortem Magnetic Resonance Imaging of In Utero Fetuses and Its Relationship With Postmortem Interval: A Multi-Organ Observational Study on Reduced Fetuses of Complicated Multiple Pregnancies.

Background: Despite technological advancements in perinatal imaging, autopsy examination is still regarded as the reference standard to determine the time and reason of the fetal death.

Purpose: This study was conducted to identify the intrauterine postmortem magnetic resonance imaging (PMMR) findings of fetuses, who underwent radiofrequency ablation (RFA).

Study Type: Prospective.

Early detection of ischemic brain injuries by diffusion-weighted imaging after radiofrequency ablation for fetal reduction in monochorionic pregnancies.

Background: This study aimed to investigate the additional advantages of magnetic resonance imaging (MRI), particularly diffusion-weighted imaging (DWI) over fetal ultrasound in the detection of acute ischemic cerebral injuries in complicated monochorionic (MC) pregnancies that underwent selective reduction by radiofrequency ablation (RFA).

Methods: This prospective cohort study was conducted on 40 women with complicated MC pregnancies who were treated by RFA. Fetal brain imaging by DWI and conventional MRI was performed either in the early (within 10 days after RFA) or late phase (after 3-6 weeks) in the surviving fetuses to detect both acute and chronic ischemic injuries.

Predictive role of Doppler indices of cerebral-placental-uterine ratio and umbilico-cerebral ratio for late-onset fetal growth restriction: a prospective cohort study.

Predicting late-onset foetal growth restriction (FGR) has proven to be rather challenging. In this study, we propose a new parameter, cerebral-placental-uterine (CPU) ratio and umbilico-cerebral (UC) ratio for this matter. Results of this study which included a total of 227 nulliparous women showed that an increase in CPU ratio (OR = 0.

Prenatal blood levels of some toxic metals and the risk of spontaneous abortion.

High-level toxic metal exposure has become rare in the recent years. Although, it has not known whether relatively lower exposure may adversely affect human reproductive system. Spontaneous abortion (SA) is a serious reproductive problem, which, in many cases, the cause(s) is not clearly understood.
