Study on Ultrasonographic Parameters in Predicting Abortion in Patients between 6-12 Weeks of Pregnancy (original) (raw)
2019, Asian Journal of Medical Radiological Research
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.

Ultrasonographic Prediction of Early Miscarriages
Background: Spontaneous miscarriage is defined as an involuntary termination of pregnancy before 20th week of gestation or spontaneous expulsion of fetus below a fetal weight of 500 gm. Antenatal ultrasonography has been extremely useful in providing better understanding the etiology of first trimester spontaneous abortion and a basis for its clinical classification and management The aims and objective of this study is to identify abnormal ultrasound parameters and correlate the ultrasonic findings with the clinical outcomes. Materials and Methods: The study included 100 pregnant women attending outpatient department or also admitted in inpatient at 5-12 weeks of gestation fulfilling inclusion and exclusion criteria. Results: The abortion rate in our study was 34%. Out of that 18% abortion occurred at< 8 weeks and 16% occurred at 8-12 weeks of gestation. In this study, 30 patients had threatened abortion out of which 23(76 %) had abnormal TVS parameters. In our study 44 patients had abnormal findings in TVS, of which 32 (72.7%) had EPF. Conclusion: This study emphasizes the role of ultrasound in prediction of early pregnancy failure in first trimester. It can also help in taking decision whether to continue, abort or follow conservative management in early pregnancy.

Background: Spontaneous miscarriage is defined as an involuntary termination of pregnancy before 20 th week of gestation or spontaneous expulsion of fetus below a fetal weight of 500 gm. 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 assess the early pregnancy developmental changes in first trimester ultrasound screening, identify abnormal ultrasound parameters and correlate the ultrasonic findings with the clinical outcomes and also to analyze the success of conservative management on patients. Methods: The study included 150 patients attending OPD/emergency within 5-12 weeks of gestation fulfilling the exclusion and inclusion criteria. Results: The abortion rate in our study was 16%. Seventy two percent of abortion occurred at 8-12 weeks of gestation. Threatened abortion was noted in 10% of the patients. Sixteen percent of patients had abnormal USG findings in terms of large yolk sac, abnormal mean sac diameter, crown rump length, embryonic bradycardia, increased resistive index and intrauterine hematoma. Conclusions: This study emphasizes the role of ultrasound in prediction of early pregnancy failure in first trimester. It also stresses on the importance of learning obstetric ultrasound and performing obstetric practice in the community with precision and perfection.

ObjectivesThe aim of this prospective study is to assess the value of ultrasonographic findings in predicting unfavourable outcome in pregnancies between 8 and 10 + 6 weeks' gestation (WG).MethodsThis is a prospective study on live embryos between 8 and 10 + 6 WG performed in a tertiary center by a single fetal medicine specialist. The local research ethic committee approved the study protocol and patients were enrolled after an informed written consent. Embryonic crown–rump length (CRL), heart rate (HR) and yolk sac diameter (YSD) were measured and new ultrasonographic findings (embryonic skin edema and hydrothorax) were evaluated transvaginally. Fetal outcome was evaluated at 22 WG. Miscarriages, chromosomal abnormalities and fetal malformations were recorded and considered as unfavourable outcome. Logistic regression analysis was used in order to evaluate if the continuous variables CRL, HR and YSD and the categorical variables skin edema and hydrothorax have a significant ef...

Purpose. To determine whether gestational sac volume (GSV) or amniotic sac volume (ASV) and/or the difference between them can predict abortion in women with first-trimester threatened abortion. Methods. Ninety patients between 6 and 12 weeks of gestation presenting with vaginal bleeding were studied. Seventy-six delivered after 24 weeks of gestation (group A) and 14 aborted before 20 weeks of gestation (group B). All patients had a singleton viable pregnancy demonstrated by transvaginal ultrasound. Gestational sac and amniotic sac volumes were measured in all the patients using three-dimensional transvaginal ultrasound with Virtual Organ Computer-aided Analysis software, and the gestational sac volume 2 amniotic sac volume (GSV 2 ASV) was calculated. Results. The groups did not differ in terms of age, parity, number of previous abortions, or term deliveries. The GSV (group A: mean 32.0 6 27.7 cm 3 ; group B: 26.7 6 29.1 cm 3) and the ASV (group A: 21.1 6 25.5 cm 3 ; group B: 20.6 6 26.0 cm 3) were not statistically different, while the GSV 2 ASV was significantly smaller in group B (aborting before week 20) (group A

Background: We sought to establish the accuracy of abdominal ultrasonography in determining gestational age and identifying the presence of a gestational sac and embryonic pole before and after medical abortion. Methods: We included all 120 women enrolled in a study of simultaneous oral mifepristone and buccal misoprostol for abortion through 63 days' gestation. Vaginal and abdominal ultrasound examinations were performed before and 24 h after medication administration. Visualization of a gestational sac and embryonic pole and presence or absence of cardiac activity were recorded. Sensitivity and specificity were calculated with the results from vaginal ultrasonography as the gold standard. The effect of body mass index (BMI) on ultrasound findings was also assessed. Results: Before treatment, the sensitivities of abdominal ultrasonography were 100% (95% CI 97-100) and 68% (95% CI 58-77) for presence of a gestational sac and an embryonic pole, respectively. Overall, abdominal imaging underestimated mean gestational age by 1.6 days (95% CI 1.0-2.2). After treatment, abdominal ultrasonography missed three of 34 retained gestational sacs (sensitivity 91%, 95% CI 76-98%). Fourteen women had gestational cardiac activity by vaginal ultrasound at follow-up. Abdominal imaging identified the gestational sac in all cases, but cardiac motion was only visible in 10 (71%, 95% CI 42-92%). For every 10-point increase in BMI, the odds ratio for missing an embryonic pole at baseline was 2.8 (95% CI 1.5-5.0). Conclusions: Abdominal ultrasonography is sensitive for diagnosing the presence or absence of a gestational sac, but less sensitive at detecting an embryonic pole. This may lead to a small underestimation of gestational age and missing a continuing pregnancy at follow-up when one exists.

Role of ultrasonography in third trimester pregnancy for early diagnosis of embryonic demise
International Journal of Reproduction, Contraception, Obstetrics and Gynecology, 2016
Background: The objective of antenatal care is to assure that every wanted pregnancy culminates in the delivery of healthy baby without impairing the health of the mother. The first trimester of intrauterine life is the most crucial period which needs careful eyes on the growing fetus inside. The aim and objective of this study was visualization & localization of the gestational sac and early identification of embryonic demise and other forms of nonviable gestation. Methods: A prospective study of 500 randomly selected patients with first trimester pregnancy at Dr. S. N. Medical College and attached group of hospitals, Jodhpur during May 2013-November 2014. Ultrasound examination of these patients was performed to screen for fetal abnormalities & uterine anomalies and identify those embryos that are still alive but at increased risk for embryonic and fetal demise. Results: Out of 500 cases studied, 196 (39.2%) pregnancies were normal. 304 cases had abnormal Ultrasonography findings. Out of these 304 cases, 87 had missed abortion, 70 had incomplete abortion and 53 cases had threatened abortion. Conclusions: Ultrasonography has an important role in screening of early pregnancies for early diagnosis of fetal demise, fetal abnormalities and uterine anomalies With recent advances in technology, first trimester sonography can now detect, or at least suggest, many structural abnormalities.
