“…Transabdominal and transvaginal examinations have their own set of advantages and disadvantages. 21 Transabdominal imaging is best suited for measurement of Nuchal translucency due to the panoramic view and scope for manipulation. Transvaginal examination helps in high resolution imaging of fetal anatomy.…”

Background: Prenatal identification of cardiac defect gives families the opportunity to receive counselling regarding the anticipated fetal and neonatal outcomes. Screening and diagnosis of congenital heart disease in the first trimester has increased over the past decade as almost all CHDs are already established by that time. Objective was to assess the feasibility of screening through first trimester echocardiography by a trained observer in low-risk populations. Methods: The study was conducted on a sample of 500 antenatal mothers of gestational age between 11-13 weeks+6 days attending a teaching hospital. Maternal age, weight, height, body mass index, parity, gestational age, obstetric history and past history were recorded. In addition to first trimester ultrasound screening for aneuploidy in foetuses, a simplified echocardiographic examination was performed. After obtaining the appropriate fetal position, Crown-rump length was documented. Nuchal translucency thickness was recorded. After examination with 2-dimensional sonography, the operator obtained the tricuspid flow and ductus venosus flow. Color flow mapping was applied for evaluating the 4-chamber view and three vessel tracheal views. Specific criteria developed for the 4-chamber view, 3 vessel trachea view, tricuspid flow and ductus venosus flow was used to assess feasibility. Results: Good feasibility was observed for all the views, with tricuspid flow showing 96% feasibility, Ductus Venosus showing 95% feasibility, 3VT view showing 90.1% feasibility and 4CV view having 89.7% feasibility. There was no significant association found between maternal BMI, CRL and the feasibility of fetal cardiac screening. Conclusions: Encouraging results of this study indicates the feasibility of fetal cardiac screening in low-risk population.

“…A recent systematic review encompassing both transabdominal and/or transvaginal POCUS examinations performed by emergency physicians reported a sensitivity of only 90% 8 . Secondly, transabdominal ultrasound demonstrates lower diagnostic accuracy compared to transvaginal ultrasound, particularly in cases of ectopic tubal pregnancy 9 , 10 , 11 . Third, it typically can only confirm the diagnosis of intrauterine gestation after the 6-8 th week of pregnancy, particularly when the fetal heart rate becomes detectable around the 8 th week 12 .…”

Managing multiple pregnancies is challenging and requires careful evaluation. Point of care ultrasound (POCUS) has emerged as a potentially crucial tool in assessing suspected first-trimester pregnancies. However, its role in evaluating multiple pregnancies remains uncertain. We present the case of a 36-year-old Ghanaian female who presented with acute vaginal bleeding after undergoing in vitro fertilization. A bedside transabdominal POCUS identified four intrauterine gestations with fetal poles and cardiac activity, suggesting a quadruplet viable pregnancy. A subsequent transvaginal ultrasound confirmed the findings. The patient was discharged with a follow-up appointment with an Obstetrician-Gynecologist. This case highlights the significance of POCUS in early pregnancy diagnosis, facilitating accurate identification and appropriate referral for further management. It also demonstrates the utility of POCUS in determining gestational age and viability. To our knowledge, no published case reports specifically address the diagnosis of a quadruplet pregnancy, emphasizing the role of POCUS in optimizing care for high-risk multiple pregnancies.

“… 10 Therefore, patients who were suspected ectopic pregnancy should be recommended to have close observation and regular follow-ups, and doctors may consider the use of transabdominal sonography in combination with transvaginal sonography to complement information, improve detection rate, and reduce or avoid misdiagnosis and missed diagnosis, which provides a scientific basis for the formulation of clinical treatment scheme. 11 In addition, 3 cases of scar pregnancy were misdiagnosed as inevitable abortion and cervical pregnancy at night; the reason was that there were similarities in the sonogram of these diseases, but their clinical management measures were quite different, so ultrasound doctors should pay attention to differential diagnosis. Riaz et al 12 summarized the key points of ultrasonic diagnosis of scar pregnancy as 1) no gestational sac was found in the uterus cavity; 2) gestation sac attaching to anterior wall of uterus in the lower section, surrounded by abundant blood flow signals, which was the key point to identify inevitable abortion; and 3) the muscular wall between the gestational sac and the bladder was thin, which could be used to further differentiate cervical pregnancy.…”

BackgroundUltrasonography, the preferred adjunct examination method and the differential diagnostic tool for gynecologic emergency, can reflect the change pattern of gynecological diseases in daytime and at night. The purpose of this study was to analyze the diseases through gynecological emergency ultrasound in daytime and at night and to evaluate the day–night difference in the accuracy of ultrasound diagnosis.Materials and methodsRetrospective analysis was performed on the 2016 clinical data of the patients who had undergone gynecological emergency ultrasound at The First Affiliated Hospital of Guangxi Medical University, and the results of the ultrasound diagnosis were compared with the clinical diagnosis.ResultsThe following categories of gynecologic emergency diseases during the daytime and at night have significant statistical differences in the constituent ratio (P<0.001); ectopic pregnancy, intrauterine pregnancy, acute pelvic inflammatory disease, no organic lesion in uterine and adnexa; while the constituent ratio of abortion and trophoblastic diseases, ovarian tumor, uterine and endometrial lesions, was no statistical difference during the daytime and at night (P>0.05). The overall coincidence rate of ultrasound diagnosis was 96.3% (daytime, 97.9%; night, 86.4%). The coincidence rates of ectopic pregnancy ultrasonography diagnosis in daytime and at night were 96.4 and 75.4%, respectively; the difference was statistically significant (P<0.001).ConclusionSince the different constituent ratio of disease between daytime and night gynecological emergency ultrasound was significantly different, and the diagnostic accuracy of ultrasound at night was low; hence, the ultrasound doctor at night should pay attention to improve the accuracy of diagnosis and the ability of differential diagnosis of ectopic pregnancy, and it is suggested that some suspected cases during the night should be reexamined again in the daytime to eliminate the errors resulted from subjective factors.
