Background: To evaluate the risk of uterine rupture during pregnancy, researchers use two-dimensional (2D) transvaginal ultrasound to assess lower uterine segment (LUS) thickness in the third trimester of pregnancy. This study aimed to compare the thickness of the LUS provided in a 2D transvaginal ultrasound with the findings during a cesarean section (C/S) of pregnant women with a history of previous C/S.
Materials and Method: This cross-sectional study was performed on 40 pregnant women referred to Izadi Obstetrics and Gynecology Hospital in Qom. All the women underwent transvaginal ultrasound followed by C/S within a maximum of one week later. Also, an expert gynecologist classified LUS thickness into four grades in the operation room.
Results: The mean age of women was 31.58 ± 4.56 years, and the mean thickness of the LUS was 2.17 ± 0.51 cm. Moreover, 57.5% of the women have grade I of LUS based on intraoperative findings. Results indicated that the mean thickness of the LUS measured by ultrasound significantly differed between the three grades detected by the gynecologist (P=0.04). However, there were no significant differences between maternal age, gestational age, parity, and time of last C/S among women with different LUS grades (P˃0.05). Transvaginal ultrasound could be helpful in evaluating the risk of scar dehiscence and uterine rupture among women with LUS grades I and II with a history of previous C/S.

Introduction: Determining the correct date of pregnancy and fetal age has a very important role in the management of pregnancy from the first trimester to delivery, which makes it necessary to know the exact method in this field. Therefore, this study aimed to compare the accuracy of ultrasound at 8-16 weeks with Naegele’s Revised Rule of the delivery date.Methods: This study was performed on 50 pregnant women. After recording demographic information and age of delivery, sonography of weeks 8-16 and Naegel’s Revised Rule were also recorded. A Paired t-test was used to compare data.Results: The results of our study showed that the average difference between the Naegele’s Revised Rule and real age was 3.52 days, which is a significant difference. However, the average difference between the estimated date by ultrasound and real age is 0.58 days, which is not a significant difference. Ultrasound is more accurate than the Naegele’s Revised Rule, which still did not differ significantly from the actual date of delivery by grouping by age, sex of the fetus, number of pregnancies, and deliveries.Conclusion: Ultrasound has more accuracy in accurately estimating the date of delivery, and therefore using this method and relying on it has more reliability than the Naegele’s Revised Rule.

Background and Objective: Infertility in women can be attributed to a wide variety of factors, including inherited and acquired abnormalities of the uterus. Ultrasonography is used for determining the thickness of the endometrium during various phases of the menstrual cycle. The purpose of this study is to determine the thickness of the endometrium in women who are unable to conceive using ultrasound imaging during the secretory phase.Methods: A total of 134 adult females between the ages of 22 and 45 were examined by means of an endo-vaginal and transabdominal approach with EVN 4-9 MHZ and CA1-7AD probes, respectively, during the course of this research project, which took place in Imam Al-Hujjah Charitable Hospital, Karbala, Iraq, between February 2021 and April 2022.Results: The findings showed that primary infertility accounted for 69.4% of cases, which was significantly higher than women with secondary infertility, which accounted for 30.6% of cases. There were 68.8% of women who presented with primary infertility who had endometrial thickness between 9-12 mm, and there were 31.1% of women who presented with secondary infertility who had this thickness. 65.8% of women who are experiencing primary infertility and 34.1% of women who are experiencing secondary infertility have an endometrial thickness of 14-18 mm. Our study showed that 40% of women who suffer from primary infertility and 60% of those who have secondary infertility have an endometrial thickness of 19-23 mm.Conclusion: When it comes to diagnosing and treating infertility, ultrasound is a crucial tool for measuring the thickness of the endometrium in women.

Fraser syndrome is a rare genetic disorder characterized by multiple structural abnormalities, above all of which are cryptophthalmos and syndactyly. According to reviews of reported cases, diagnostic criteria have been established. Here, we report a case of 18 weeks pregnancy diagnosed with Fraser syndrome presenting with cryptophthalmos, syndactyly, kidney agenesis, and hyper-echogenic lungs during an ultrasound examination. The pregnancy was terminated, and diagnostic features of the syndrome were confirmed afterward. Since the imaging characteristics are unique, it is of value that clinicians become familiar with the appearance of the syndrome to provide families with the opportunity to make timely decisions regarding pregnancy termination and use the prenatal diagnostic tools to have healthy children in subsequent pregnancies.

Perivascular epithelioid cell tumors (PEComas) are a group of mesenchymal neoplasms with different biological presentations from benign to malignant types. Hence, we report the first description of PEComa presenting with an acute surgical abdomen. Her definite diagnoses were made based on the histomorphology results at Imam Khomeini Hospital, Tehran University of Medical Sciences, in 2020.Considering different clinical presentations, unknown characteristics of imaging, and rarity of PEComa, preoperative diagnosis of it seems impossible. However, IHC can play an important role in its diagnosis.

Background & Objective: IUGR (intrauterine growth restriction) fetuses have been known as a significant concern in clinical practice. It is associated with fetal mortality and morbidity and prenatal adverse cardiac remodeling. The aim of this study is the evaluation of the relation between MPI (myocardial performance index) abnormalities and doppler findings in both normal and IUGR fetuses.Materials & Methods: In this cross-sectional study, 400 consecutive pregnant women in Shariati Hospital, Tehran, Iran, in 2019 and 2020 underwent ultrasound assessment at 28-40 weeks, in which among the 400 performed ultrasounds, 47 fetuses with IUGR were selected as a case group, and 47 fetuses with normal weight were selected based on AGA (appropriate gestational age). Cardiac function was evaluated by measuring MPI in diastolic and systolic function in two groups. The results were compared to the IUGR (case group) and control group by SPSS software version 20.Results: In receiver operating characteristic (ROC) analysis, the AUC (area under the curve) for left ventricular MPI (LV MPI) was 0.929 (CI95%: 0.868-0.991; P < /em>=0.001), and the sensitivity and specificity values were 87% and 69.4% with a cut-off point of 0.2850. In ROC analysis, the area under the curve for RV MPI was 0.842 (CI95%: 0.741-0.942; P < /em>=0.001), and the sensitivity and specificity values were 78.3% and 63.9%, with a cut-off point 0.2850. Left and right ventricular MPI showed a significant difference statistically between the case and the control groups.Conclusion: The study showed a significant rise of MPI in IUGR fetuses. MPI can be considered as a useful parameter for evaluating the severity of growth restriction in IUGR fetuses.

Currently, ultrasound is a well-known clinical modality for pregnancy management and has a prominent role in clinical decision-making. Accordingly, developing guidelines to outline the minimum performance standards of using ultrasound is necessary for different areas of obstetric ultrasound. The fetal brain is one of the most important assessments in anomaly scan. For a basic brain assessment, 3 axial planes are routinely defined. According to most guidelines, the fetal skull’s integrity, shape, and bone density should be assessed while measuring the head size. In this paper, we present 2 cases of skull bony defect with normal routine 3 axial planes. For better detection of CNS anomalies, it is necessary to add other views such as sagittal view to three routine planes. It leads to early detection of anomalies especially in first and early second trimester. Consequently, it helps in deciding for termination, planning interventions and further management.
