“…Amongst non viable pregnancies, 66.66% were primigravidia. Our Kumari S et al [9] and Warburton D et al [11] reported similar observations. Initial period of conception is most vital, as majority of the abortions occur before 12 weeks gestational age and fewer than 5% occur after identification of fetal heart activity.…”

Background:The introduction of ultrasound into the obstetrical practice has been extremely useful in providing better understanding of the etiology of the first trimester spontaneous abortion and a basis for its clinical classification and management. The aims and objective of this study is to study the ultrasonographic parameters between 6 to 12 week of pregnancy in predicting early abortion, to assess the predictive value of ultrasonographic parameters in predicting early pregnancy and to study the associated maternal factor in present pregnancy in predicting early pregnancy loss. Subjects and Methods: The study included 120 patients attending OPD/emergency within 6-12 weeks of gestation, fulfilling the exclusion and inclusion criteria. Results: Out of 120 pregnancies, 24 pregnancies were non viable, out of which 41.66% were >30years of age. 62.5% of abortions occurred at 8-12 weeks of gestation. 17.5% females had abnormal gestation sac diameter, 6.60% females had abnormal crown rump length, 9.70 % females had abnormal yolk sac and 1 % had abnormal fetal heart rate. Conclusion: This study demonstrated that sonographic parameters, such as abnormal gestational sac diameter, small or large yolk sac diameter, abnormal Crown rump length and decreased fetal heart rate are associated with an increased likelihood of miscarriage. Combining these parameters may provide improved prediction of miscarriage.

“…While the use of first-trimester parameters for gestational age assessment has been vastly popular and widely used, their role in predicting pregnancy outcomes has seen limited exposure. While some investigators have found some of the first trimester ultrasound parameters including mean sac diameter (MSD), crown-rump length (CRL), yolk sac diameter (YSD), embryonic/fetal heart rate (FHR), and subchorionic hemorrhage to be possible predictors of adverse pregnancy outcomes, others have dismissed the significance of such associations [ 4 , 5 , 6 , 7 ]. This study attempts to find out the correlation between the crown-rump lengths (CRL) observed in the first-trimester ultrasound and the birth weight of the neonate upon completion of the pregnancy, with low birth weight (absolute weight of <2500 g regardless of gestational age) being a significant contributor to neonatal morbidity and mortality, especially in the South Asian population.…”

BackgroundUltrasound examination has been a crucial part of the evaluation of fetal health during pregnancy. It has become more accurate over the past few decades as a result of advances in radiodiagnostic imaging. While obstetric ultrasonography in the first trimester has been utilized extensively for gestational age assessment and confirmation of fetal viability, the imaging technique has seen little exposure in predicting pregnancy outcomes. This study was thus undertaken to find out any possible association between one of the first trimester parameters, i.e. crown-rump length (CRL) noted at the beginning of a pregnancy, and the birth weight of the neonate. MethodsThis prospective cohort study conducted at a teaching hospital in India spanning over a period of eighteen months included women with a spontaneously conceived intrauterine pregnancy at six to ten weeks period of gestation as calculated from the last menstrual period. Transvaginal sonography was performed for all such women and the CRL was noted. These CRL values were then compared to a standard nomogram and assigned to either of three categories i.e. CRL <5 th centile, 5 th to 95 th centile, or >95 th centile. The women were then followed up at the hospital with standard care till the end of their pregnancy, and finally, the birth weights were noted. Data were recorded in an MS Excel spreadsheet program and analysis was performed with regard to CRL in the first trimester and birth weights using SPSS v23 (IBM Corp.). ResultsCrown-rump lengths and birth weights of 104 cases were evaluated. The mean age of the study population was 26.6 years and the mean period of gestation (weeks) was 8.28 ± 1.01. The incidence of low birth weight (LBW) in the study was 22.1%. The distribution of LBW was significantly different between the three CRL categories (χ2 = 15.868, p = <0.001), being considerably higher in the CRL <5 th centile category. No embryos with CRL >95 th centile had low birth weight. ConclusionsOur study suggested a congruence between the crown-rump length of an embryo noted in the first trimester and its weight at birth, with low birth weight being a fairly common occurrence in the deficient CRL category. This study highlights the role of a carefully performed first-trimester ultrasound examination in possibly predicting an adverse pregnancy outcome such as low birth weight and the probable inherent tendency of growth restriction in fetuses that are destined to develop the same.

“…Majority of the subjects in the present study were in the age of 21-30 years which was comparable with the previous studies. [14][15][16] One of the most important aspects of obstetric ultrasound in the 1st trimester is the dating of pregnancy; this is accomplished by performing a few simple biometric measurements: the GS diameter, when no embryo is seen;…”

Background: The first trimester begins on the first day of the last menstrual period (LMP) and lasts until the end of 12 weeks of gestation. Transvaginal ultrasound is modality of choice for establishing the presence of an intrauterine pregnancy in the first trimester. The focus of our study is routine early pregnancy ultrasound. The purpose of this study was to diagnose various conditions of pregnancy at an early stage by using ultrasound.Methods: We conducted retrospective data analysis of random 250 pregnant patients who had undergone first-trimester ultrasonography USG) (transvaginal/abdominal) in their first antenatal visit at S.V.P. Hospital, Ahmedabad, Gujarat, India from March 2021 to February 2022. The patient was selected by a simple randomized method. Maternal age, parity, gestational age, and special features regarding maternal gestational history were compared with USG findings. Patients were divided into 13 groups on the basis of ultrasonographic diagnosis.Results: We noted 76.8% of patients had single, viable, intrauterine pregnancies, while 23.2% had complicated pregnancies with uterine anomalies, ovarian cysts, leiomyoma, caesarean scar pregnancy or subchorionic hematomas.Conclusions: Ultrasound measurement of fetus in first trimester is most accurate method to confirm gestational age. It is less expensive and easily available modality. First-trimester ultrasound is useful to define embryonic landmarks in developmental stages with reference to gestational age, early diagnosis of miscarriage, ectopic pregnancy, molar pregnancy, multifetal pregnancy, major fetal malformation. And also, to diagnose pregnancy with leiomyoma, caesarean scar pregnancy, uterine anomaly and pre-eclampsia with the help of uterine artery PI.
