RESUMO

Background: Most pregnant epilepsy patients need to continue using anti-seizure medications (ASMs) to control epileptic seizures. Objective: This study aimed to evaluate the risk of early abortion in pregnant epilepsy patients exposed to anti-seizure monotherapy. Methods and Material: We prospectively followed up pregnant epilepsy patients treated with anti-seizure monotherapy in our epilepsy center between January 2010 and January 2020 under real-world conditions. Early abortion (spontaneous abortion in the first trimester of pregnancy) was the endpoint. Results: Of 211 pregnancies exposed to monotherapy, including 40% (n = 85) to lamotrigine (LTG), 28% (n = 58) to oxcarbazepine (OXC), 15% (n = 32) to sodium valproate (VPA), 9% (n = 19) to levetiracetam, and 8% (n = 17) to carbamazepine, six ended in early abortion. The overall risk of early abortion in pregnant patients exposed to ASM monotherapy was 2.8% (n = 6) [95% confidence interval (CI) = 0.013-0.073]. The risk of early abortion was 2.4% (n = 2) (95% CI = 0.003-0.082) in women treated with LTG, 3.5% (n = 2) (95% CI = 0.004-0.115) in women treated with OXC, and 6.3% (n = 2) (95% CI = 0.008-0.208) in women treated with VPA. The relative risk of early abortion in the LTG, OXC, and VPA groups did not reach statistical significance. Conclusions: Although the sample size of our study was small, these results indicate that the use of anti-seizure monotherapy in pregnant epilepsy patients may not increase the risk of early miscarriage. Larger prospective studies are needed for sufficient statistical analysis.

RESUMO

OBJECTIVES: To gain a deeper understanding of perspectives on abortion and early abortion bans in a restrictive US state. STUDY DESIGN: We conducted a qualitative study using semistructured Zoom interviews with residents of the US state Georgia's 6th Congressional District. Potential participants first completed a screening tool to recruit people who held "middle-of-the-spectrum" views on abortion based on two abortion questions on a 5-point Likert scale. The interviews focused on participants' thoughts and feelings on abortion and Georgia's early abortion ban. We transcribed, coded, and analyzed the interviews, and present a subset of themes. RESULTS: We interviewed 28 people from March to May 2020. Participants often described holding complex views on abortion shaped by a range of lived experiences, values, and identities. They lamented the "black-and-white" nature of the national abortion discussion, which they felt oversimplified the issue and did not represent their views. Participants discussed the importance of experiences that allowed them to empathize with people who choose abortion, even when they personally felt they would make a different decision in a similar situation. Based on these experiences, many participants emphasized the importance of separating their own views on abortion from what needed to be regulated for others. However, participants often demonstrated a lack of understanding about the extent to which HB481 makes abortion inaccessible in Georgia. CONCLUSIONS: Our results indicate that, even in states traditionally labeled as restrictive or hostile towards abortion, many people express an openness to understand others' experiences and hold complex and multifaceted views. IMPLICATIONS: Our laws and policies at the state level profoundly affect the practice of medicine and access to care. Our study furthers our understanding of how a sample of people in a restrictive US state think and feel about abortion and early abortion bans. These results can be used to support educational efforts, policies, and communication practices that better reflect the complex views of the public.

RESUMO

PURPOSE: To compare aneuploidy rates in early aborted tissues or blastocysts between in vitro fertilization (IVF) cycles after the gonadotropin-releasing hormone (GnRH) antagonist (GnRH-ant) protocol or the GnRH agonist (GnRH-a) long protocol. METHODS: This was a retrospective cohort study from a university-affiliated fertility center. In total, 550 early miscarriage patients who conceived through IVF/intracytoplasmic sperm injection (ICSI) after receiving the GnRH-ant or GnRH-a long protocol were analyzed to compare aneuploidy rates in early aborted tissues. To compare aneuploidy rates in blastocysts, 404 preimplantation genetic testing for aneuploidy (PGT-A) cycles with the GnRH-ant protocol or GnRH-a long protocol were also analyzed. RESULTS: For early miscarriage patients who conceived through IVF/ICSI, compared to the GnRH-a long protocol group, the GnRH-ant protocol group had a significantly higher rate of aneuploidy in early aborted tissues (48.51% vs. 64.19%). Regarding PGT-A cycles, the rate of blastocyst aneuploidy was significantly higher in the GnRH-ant protocol group than the GnRH-a long protocol group (39.69% vs. 52.27%). After stratification and multiple linear regression, the GnRH-ant regimen remained significantly associated with an increased risk of aneuploidy in early aborted tissues and blastocysts [OR (95% CI) 1.81 (1.21, 2.71), OR (95% CI) 1.65 (1.13, 2.42)]. Furthermore, the blastocyst aneuploidy rate in the GnRH-ant protocol group was significantly higher but only in young and normal ovarian responders [OR (95% CI) 5.07 (1.99, 12.92)]. CONCLUSION: Compared to the GnRH-a long protocol, the GnRH-ant protocol is associated with a higher aneuploidy rate in early aborted tissues and blastocysts. These results should be confirmed in a multicenter, randomized controlled trial.

RESUMO

During preparation for early abortion in Norway, an ultrasound examination is usually performed to determine gestation and viability. This article aims to provide a deeper understanding of women's and health care personnel's (HCP) experiences with ultrasound viewing during abortion preparation in the first trimester. Qualitative in-depth interviews with women who had been prepared for early abortion and focus group interviews with HCP from gynaecological units were carried out. A hermeneutic-phenomenological analysis, inspired by van Manen, was chosen. Thirteen women who were pregnant and considering abortion in their first trimester and 20 HCP, namely, 19 registered nurses and one medical doctor, were recruited from gynaecological units at six hospitals. The study was approved by the ethics committee (2014/1276). The essential meaning structure of 'autonomy under pressure' consisted of two themes that expressed the different experiences of both the women and the HCP, namely, expectations versus precautions and choice versus protection. The women and HCP expressed different attitudes before the consultation that affected their experiences of the ultrasound examination. While the women had expectations of a clarification based on their choice to either see or not see the ultrasound image, HCP seemed to be more concerned with predetermined rules that they believed would protect the women. Consequently, the basis for dialogue was not optimal, and women's autonomy was under pressure. Health care personnel are ethically challenged during preabortion ultrasound examinations. Meeting the individual woman's needs and respecting her autonomy during preparation for abortion requires sensitivity, involvement, and dialogue skills by health personnel. According to the woman's desire to be informed about the possibility of viewing the image during the abortion preparations, a dialogue that is focused in this direction should arise before the examination.

RESUMO

OBJECTIVE: To define serum human chorionic gonadotropin (hCG) decline following complete aspiration abortion. STUDY DESIGN: We performed a secondary analysis of 86 patients who underwent uncomplicated aspiration abortion for ultrasound-confirmed pregnancy ≤42 days gestation and had serum hCG at the time of aspiration and within 3 days postprocedure. RESULTS: Median hCG declines were 72.9% by day 1 (n = 14), 87.6% by day 2 (n = 50), and 92.8% by day 3 (n = 22). Ninetieth percentile declines were 67.8%, 81.5%, and 90.8%. Minimum hCG declines were 56.2%, 77.3%, and 83.2%. Trends did not vary by gestational age or by initial hCG <3000 mIU/mL. CONCLUSION: Postprocedure hCG trend varies over the first few days in early gestation. At ≤42 days gestation, serial hCG decline at 1 day after completed aspiration abortion is greater than 50%, consistent with the decline observed in medication abortion. IMPLICATIONS: This study confirms previously estimated human chorionic gonadotropin decline after aspiration abortion of at least 50% at 24 hours for completed procedure in very early gestations. Minimum declines on days 2 and 3 are approximately 70% and 80%.

RESUMO

BACKGROUND: Gestational age estimation is key to the provision of abortion, to ensure safety and successful termination of pregnancy. We compared gestational age based on reported last menstrual period and ultrasonography among a large sample of women in Mexico City's public first trimester abortion program, Interrupcion Legal de Embarazo (ILE). METHODS: We conducted a retrospective study of 43,219 clinical records of women seeking abortion services in the public abortion program from 2007 to 2015. We extracted gestational age estimates in days based on last menstrual period and ultrasonography. We calculated the proportion of under- and over-estimation of gestational age based on last menstrual period versus ultrasonography. We compared overall differences in estimates and focused on discrepancies at two relevant cut-offs points (70 days for medication abortion eligibility and 90 days for ILE program eligibility). RESULTS: On average, ultrasonography estimation was nearly 1 (- 0.97) days less than the last menstrual period estimation (SD = 13.9), indicating women tended to overestimate the duration of their pregnancy based on recall of date of last menstrual period. Overall, 51.4% of women overestimated and 38.5% underestimated their gestations based on last menstrual period. Using a 70-day limit, 93.8% of women who were eligible for medication abortion based on ultrasonography would have been correctly classified using last menstrual period estimation alone. Using the 90-day limit for ILE program eligibility, 96.0% would have been eligible for first trimester abortion based on last menstrual period estimation alone. CONCLUSIONS: The majority of women can estimate gestational age using last menstrual period date. Where available, ultrasonography can be used, but it should not be a barrier to providing care.

RESUMO

OBJECTIVE: To compare adverse outcomes of medication and aspiration abortion among those with intrauterine pregnancy <43 days gestation versus abortions performed at 43-48 days. STUDY DESIGN: We conducted a multicenter retrospective chart review study to review all medication and aspiration abortion of visualized pregnancy <49 days gestation at Planned Parenthood Columbia Willamette (Oregon) and Planned Parenthood of Orange and San Bernardino Counties (California) in 2014-2015. We identified incident cases by billing codes and performed chart review for adverse outcomes (ED visits, incomplete abortion), need for further interventions, or complications (hemorrhage, infection, and uterine perforation), captured up to 90 days post-abortion. RESULTS: The 3930 abortions during the study period at the two sites included 2914 medication abortions and 1016 aspiration abortions, with 1470 medication abortions and 469 aspiration abortions at <43 days gestation. Composite adverse outcomes did not vary by gestation, for either medication abortion (75/1470; 5.1% for <43 days versus 94/1444; 6.5% at 43-48 days, p = 0.10) or aspiration (12/469; 2.6% for <43 days versus 16/547; 2.9% at 43-48 days, p = 0.72). Fewer incomplete abortions (ongoing pregnancy, symptomatic retained tissue, or retained gestational sac) occurred in the earlier gestational group (3.1% for <43 days versus 4.3% at 43-48 days, p = 0.04). Composite adverse outcomes were higher after medication versus aspiration abortion (169/2914; 5.8% versus 28/1016; 2.7%, p < 0.01). CONCLUSION: Medication and aspiration abortion performed either before or during the sixth week of ultrasound-confirmed intrauterine pregnancy have low rates of composite adverse outcomes, including complications or incomplete abortion. However, unplanned interventions are more common after medication compared to aspiration abortions. IMPLICATIONS: Very early medication and aspiration abortion are similarly safe and effective before or during the sixth week of ultrasound-confirmed pregnancy, though subsequent interventions are more likely after medication abortion. Patients with early pregnancy can safely initiate abortion with follow-up to ensure complete abortion.

RESUMO

One of the causes of observed low fertility is embryo loss after fertilization. Previous findings suggested that more than half of fertilizations result in embryo loss before pregnancy is detected. We proposed reinsemination between 49 and 100 d after the first insemination as an indicator trait for early abortion (EA) in dairy cattle based on the mean estrus interval of 21 d. This trait was compared with conception rate from first insemination and conception status, computed as the inverse of the number of inseminations to conception. Animal model variance components were estimated by REML, including parents and grandparents of cows with records. First-parity heritability for first insemination conception rate was 3%. In the multitrait analysis of parities 1 to 3 for putative EA, heritabilities ranged from 8.9% for first parity to 10.4% for second parity. All genetic correlations were >0.9, whereas all environmental correlations were <0.12. The variance component for the service sire effect for putative EA rate was less than half the variance component for conception rate. Thus, genetic control of the 2 traits is clearly different, and analysis of EA rate by a single-trait animal model is justified. Genetic evaluation for putative EA was computed using this model, including all first- through third-parity cows with freshening dates from January 1, 1985, through December 31, 2016, that either became pregnant on first insemination or were reinseminated between 49 and 100 d after the first insemination. All known parents and grandparents of cows with records were included in the analysis. The regression of the breeding value for non-abortion rate on the cows' birth year was 0.083%/yr. The genetic correlation between first-parity EA and conception status was 0.995. The genetic correlations between first-parity EA and milk, fat, and protein production were all negative, whereas the genetic correlation between EA and herd life was 0.33. Inclusion of putative EA in the selection index instead of conception status resulted in 10 to 20% greater genetic gain for both fertility traits. In a genome-wide association study based on 1,200 dairy bulls with reliabilities >50% for abortion rate genotyped for 41,000 markers, 6 markers were found with nominal probabilities of <10-12 to reject the null hypothesis of no effect on EA rate. The markers with the lowest probabilities for EA rate were also included among the markers with the lowest probabilities for female fertility, but not vice versa. The marker explaining the most variance for abortion rate is located within the ABCA9 gene, which is found within an ATP-binding cassette (ABC) genes cluster. The ABC family is the major class of primary active transporters in the placenta.

RESUMO

OBJECTIVE: To assess anti-Müllerian hormone (AMH) levels as a marker of early abortion in the first trimester among women younger than 35 years. METHODS: Prospective study of women aged 18-34 years with a spontaneous pregnancy at less than 12.6 gestational weeks in Lódz, Poland, between January 2017 and November 2018. Cases of anembryonic abortion and assisted conception were excluded. Blood samples were collected and assayed for serum AMH levels. Data were compared between women with an embryo with no cardiac activity by ultrasound (n=30) and those with a normal embryo (n=33) by using Statistica12 software. RESULTS: The 10th and 90th percentiles of serum AMH concentration among control women were used to identify a reference AMH range (1.1-4.5 ng/mL). Risk of pregnancy loss in the first trimester was found to be higher for both low AMH (<1.1 ng/mL; relative risk [RR], 3.66; 95% confidence interval [CI], 2.1-6.4; P<0.001) and high AMH (>4.5 ng/mL; RR, 3.0; 95% CI, 1.61-5.59; P<0.001). CONCLUSIONS: Both very low and very high AMH concentrations were found to significantly increase the risk of abortion in the first trimester of pregnancy. Serum AMH might be a valuable marker to predict the risk of early abortion.

RESUMO

INTRODUCTION: Women are increasingly presenting for abortion at very early gestation. However, providers may be reluctant to conduct abortion at this stage as they may be concerned that they cannot exclude an ectopic pregnancy or that they may terminate a non-viable pregnancy, or may be concerned that both medical and surgical methods may be less effective at this stage of gestation. This provider concern may result in delays in the abortion as additional investigations may be required until an intrauterine pregnancy can be confirmed. Additional unnecessary visits may be distressing for women and waste health service resources. The objective of this systematic review was to determine whether it is safe and effective to initiate abortion before there is ultrasound evidence of an intrauterine pregnancy. MATERIAL AND METHODS: We searched Embase Classic, Embase; Ovid MEDLINE® Epub Ahead-of-Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE® Daily, Ovid MEDLINE®; and Cochrane Library on 25 October 2019. Eligible studies were randomized and non-randomized comparative studies, published in English from 1985, comparing initiation of abortion before there is definitive evidence of an intrauterine pregnancy with initiation afterwards. We assessed risk-of-bias using the Newcastle-Ottowa scale. All outcomes were analyzed as risk ratios (RR) and meta-analyzed using the Mantel-Haenszel method. The quality of the evidence was assessed using GRADE. RESULTS: Two non-randomized studies (n = 3785) showed no differences in "missed ectopic pregnancy" (RR = 0.26, 95% CI 0.03-2.12), "ongoing pregnancy" (RR = 1.06, 95% CI 0.34-3.34), or "complete abortion without surgical intervention" (RR = 1, 95% CI 0.98-1.02) between initiation of medical abortion before or after ultrasound evidence of an intrauterine pregnancy. A third non-randomized study (n = 1530) showed no differences between initiation of surgical abortion before or after ultrasound evidence of an intrauterine pregnancy in "missed ectopic pregnancy" (no events), "ongoing pregnancy" (RR = 0.56, 95% CI 0.03-11.59) or "complete abortion without repeat surgical intervention" (RR = 1, 95% CI 0.99-1.01). The quality of evidence was very low. CONCLUSIONS: Initiation of abortion before there is definitive ultrasound evidence of an intrauterine pregnancy in women without signs or symptoms of an ectopic pregnancy should be considered.

RESUMO

Objective: To examine the cellular distribution and the expression of CD200 and its receptor 1 (CD200R1) in human deciduas in first-trimester pregnant women with spontaneous early abortion (SEA) and normal pregnancy, and to explore their role in the etiology of SEA.Subjects and methods: Thirty-five women at 6-10-week gestation with SA and 30 women of similar gestational age with a healthy pregnancy were recruited. Expression of CD200 and CD200R1 in the deciduas was determined using immunohistochemistry, confocal laser scanning microscope, Western blot, and real-time PCR (RT-PCR).Results: The decidual stromal cells, glandular epithelial cells, and vessel endothelial cells during the first trimester of pregnancy express both CD200 and CD200R1 proteins. During this period, the expression of CD200 in glandular epithelial cells and vessel endothelial cells is significantly higher in normal pregnancy than that in women with SEA (0.3079 ± 0.0674 versus 0.2735 ± 0.0515; 0.4077 ± 0.1366 versus 0.3249 ± 0.0993); the expression of CD200R1 in stromal cells, decidual stromal cells, glandular epithelial cells is significantly higher during normal pregnancy than SEA (0.2574 ± 0.0588 versus 0.2292 ± 0.0415; 0.3617 ± 0.1046 versus 0.2804 ± 0.0640). Western blot analysis showed an approximately 44% decrease in CD200R1expression in decidua in the SEA versus the controls. Finally, in decidua, the expression of both CD200 protein and CD200R1 transcript are significantly higher in healthy first-trimester pregnancy than in SEA (CD200: 2.2089 ± 1.2754 versus 0.7241 ± 0.2143; CD200R1: 15.7843 ± 10.7085 versus 7.3381 ± 5.8529).Conclusions: Women with SEA have a lower level of CD200 and CD200R1 expression in deciduas compared with normal pregnant women suggesting that under physiological conditions, CD200 and CD200R1 expression by deciduas is important to prevent fetal loss ensure a successful pregnancy.

RESUMO

Chemerin is a cytokine that attracts much attention in the reproductive process. This study aimed to explore the effects of chemerin and its receptor chemokine-like receptor 1 (CMKLR1) on the maintenance of early pregnancy. The expression levels of chemerin and CMKLR1 in the decidua tissues of 20 early normal pregnant women and 20 early spontaneous abortion women were examined by Western blot and real-time polymerase chain reaction analyses. CMKLR1 receptor antagonist (α-NETA) was then intrauterinely injected into normal pregnant mice model to assess its effect on the outcome of pregnancy and the phosphorylation rate of ERK1/2 in decidua tissues.We found that the expression level of chemerin in women who had experienced early spontaneous abortion was lower than in those who had experienced normal early pregnancy (P < 0.01); conversely, CMKLR1 expression was higher in the former than in the latter (P < 0.01). In a pregnant-mouse model, the embryo resorption rate of α-NETA group was higher than that in the negative control group (61.5% vs. 10.8%) (P < 0.001). Compared with the control group, ERK1/2 phosphorylation in decidua tissues decreased in the α-NETA-treated group (P < 0.01). These results suggested that the inhibition of the chemerin/CMKLR1 signaling pathway can lead to the abortion of mouse embryos, and that chemerin/CMKLR1 may play an important role in the maintenance of early pregnancy possibly by regulating ERK1/2 phosphorylation.

RESUMO

OBJECTIVE: This guideline reviews the evidence relating to the provision of first-trimester medical induced abortion, including patient eligibility, counselling, and consent; evidence-based regimens; and special considerations for clinicians providing medical abortion care. INTENDED USERS: Gynaecologists, family physicians, registered nurses, midwives, residents, and other healthcare providers who currently or intend to provide pregnancy options counselling, medical abortion care, or family planning services. TARGET POPULATION: Women with an unintended first trimester pregnancy. EVIDENCE: Published literature was retrieved through searches of PubMed, MEDLINE, and Cochrane Library between July 2015 and November 2015 using appropriately controlled vocabulary (MeSH search terms: Induced Abortion, Medical Abortion, Mifepristone, Misoprostol, Methotrexate). Results were restricted to systematic reviews, randomized controlled trials, clinical trials, and observational studies published from June 1986 to November 2015 in English. Additionally, existing guidelines from other countries were consulted for review. A grey literature search was not required. VALUES: The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force for Preventive Medicine rating scale (Table 1). BENEFITS, HARMS AND/OR COSTS: Medical abortion is safe and effective. Complications from medical abortion are rare. Access and costs will be dependent on provincial and territorial funding for combination mifepristone/misoprostol and provider availability. SUMMARY STATEMENTS: Introduction Pre-procedure care Medical abortion regimens Providing medical abortion Post-abortion care RECOMMENDATIONS: Introduction Pre-procedure care Medical abortion regimens Providing medical abortion Post-abortion care.

RESUMO

OBJECTIVES: To investigate whether starting progestin-only contraception immediately after mifepristone reduced the efficacy of early medical abortion with a mifepristone-misoprostol regimen. METHODS: A review of patient records from October 1, 2012 to March 31, 2013 from four Marie Stopes Mexico clinics in Mexico City was conducted. Patients were eligible for inclusion if they had undergone a medical abortion with mifepristone-misoprostol at no later than 63days of pregnancy, had a recorded outcome, and had either started progestin-only contraception immediately after mifepristone administration or had not started contraception. The primary outcome-successful induced abortion-was defined as the complete evacuation of uterine contents without the need for further intervention. A secondary outcome was the number of induced abortions completed without the need for manual vacuum aspiration. RESULTS: Records from 2204 patients were included; 448 (20.3%) patients had started progestin-only contraception, and 1756 (79.7%) had not. Patients not taking progestin-only contraception were significantly more likely to be primigravidas and nulliparous. Medical abortion success did not vary between the two groups; 1890 (85.8%) were successful and 2085 (94.6%) were completed without the need for manual vacuum aspiration. Different methods of progestin-only contraception did not affect medical abortion outcomes. CONCLUSION: Beginning progestin-only contraception immediately following mifepristone for early medical abortion was not associated with reduced medical abortion effectiveness.

RESUMO

BACKGROUND: There is a need to elucidate what affects the implantation and early pregnancy course in pregnancies conceived with assisted reproductive technology (ART) so that pregnancy rates and outcomes can be improved. Our aim was to determine the role of maternal Helicobacter pylori infection. MATERIAL AND METHODS: We did a prospective study of 187 infertile couples undergoing intracytoplasmic sperm injection (ICSI) and segregated those according to underlying infertility etiology. We assessed the status of H. pylori IgG antibodies and anti-CagA IgG antibodies by ELISA assay. All pregnancies were followed for early pregnancy loss (EPL, first 12 weeks). RESULTS: The likelihood of H. pylori infection increased with age (1.01, 95% confidence interval [CI]: 1.0-1.13; P = 0.040) but there was no association with EPL. Women infected with CagA-positive strains were more likely to have EPL (19.39, 95% CI: 1.8-208.4; P = 0.014). Women with tubal factor or ovulatory disorder infertility were more likely to abort early (12.95, 95% CI: 1.28-131.11; P = 0.030, 10.84, 95% CI: 1.47-80.03; P = 0.020, respectively). There was no association between EPL and age, number of embryos formed or transferred, or number of oocytes retrieved. CONCLUSION: Our findings suggest that infection with CagA-positive H. pylori strains is linked to an increase in women's potential to abort early (possibly through increased release of inflammatory cytokines). In addition, tubal factor and ovulatory disorder infertility are linked to EPL after ICSI due to unknown mechanisms. Proposals to eradicate H. pylori infection prior to ICSI could lead to a decrease in EPL after ART.

RESUMO

Early fetal growth delay and early oligohydramnios have been suspected as signs of embryonal jeopardy. However, little information is available for the prediction of early abortion. Sonographic examination of 111 early pregnancies between the sixth and ninth gestational week with regular, 28 day menstrual cycles was performed to investigate predictable sonographic findings of early abortion. Sonographic measurements of the gestational sac (G-SAC), crown-rump length (CRL) and fetal heart rate (FHR) were performed using a linear array real time transducer with Doppler. All measurements of 17 early abortions were compared to those of 94 normal pregnancies to investigate the objective rules for the screening of early abortion. Most of the early aborted pregnancies were classified correctly by discriminant analysis with G-SAC and CRL (G-SAC = 0.5222 CRL + 14.6673 = 0.5 CRL + 15, sensitivity 76.5% specificity 96.8%). With the addition of FHR, 94.1% of early abortions could be predicted. In conclusion, sonographic findings of early intrauterine growth retardation, early oligohydromnios and bradycardia can be predictable signs for the poor prognosis of early pregnancies.
