Introduction: The ductus venosus is a small funnel shaped vessel found posterior to the fetal liver connecting the intra-abdominal umbilical vein and the inferior vena cava. It is one of the three physiological shunts in the fetus. The main objective of this study is to construct the reference table and normogram for fetal ductus venosus Pulsatility Index and diameter with gestational age. Methods: This was a prospective cross sectional study conducted during August 2011 to July 2012 taking 294 uncomplicated pregnancies using systemic random sampling method. Three measurements were made for ductus venosus diameter and Pulsatility Index in each fetus during period of fetal quiescence. Results: The ductus venosus diameter at <20weeks, 20-25 weeks, 25-30 weeks, >30 weeks were 1.16, 1.31, 1.62, 1.81 and Pulsatility Index at <20weeks, 20-25 weeks, 25-30 weeks, >30 weeks were 0.41, 0.44, 0.41 and 0.41 respectively. Conclusions: The mean diameter of the ductus venosus was linear across gestational age. The Pulsatility Index shows a scattered distribution across the gestational age. Keywords: ductus venosus diameter; gestational age; Pulsatility Index.

This cross sectional study was carried out on 60 pregnant Bangladeshi women in the department of Radiology and Imaging, BIRDEM for measurement of Pulsatility Index (PI) of umbilical artery of their fetuses by duplex colour Doppler sonography during 2nd and 3rd trimester of pregnancies. Considering total 2nd and 3rd trimesters the mean PI value of umbilical artery was 1.24 (SD±0.27). While considering the gestational in separate trimesters, study showed that the value of PI in 2nd trimester was 1.33 (SD±0.29) and in 3rd trimester PI was 1.18 (SD±0.25). Paired t test shows there was a highly significant (t=35.79, df=59, Level of significance=0.001) difference between mean values of PI in different gestational ages. It was observed that there was gradual decrease of PI value with increase of gestational age (r= -0.207) but this decrease of PI was not statistically significant (p=0.113). Regression analysis between dependent PI value and independent gestational age showed linear negative relationship but this was not statistically significant (p=0.11). This study revealed that the Pulsatility index of umbilical artery was decreased with increase of gestational age from 2nd to 3rd trimester.

Background: Ultrasonographic assessment of gestational age by using different foetal parameter such as BPD, FL, AC are highly reliable in first and second trimester in pregnancy. In third trimester reliability of any single parameter has limitations. Methods: This was a hospital based comparative cross-sectional study done in the Department of Obstetrics and Gynaecology, S.M.S. Medical College and attached hospitals, Jaipur, Rajasthan. The period of study was from June 2018 to October 2019. Results: The mean TCD at 15 weeks and 40 weeks was 15.00 ± 0.00mm and 53.33±1.155mm respectively. The mean BPD at 16 weeks and 40 weeks was 33.50±0.70mm and 93±1.528mm respectively. The mean HC at 15 weeks and 40 weeks was 111.00±1,41mm and 340±2.00mm respectively. The mean FL at 15 weeks and 40 weeks was 18.50±0.70mm and 77.67±1.528mm respectively. The mean AC at 15 weeks and 40 weeks was 99.00±1.41mm and 365.33±8.32mm respectively. Conclusion:  We conclude that foetal transcerebellar diameter can thus be used as an alternative foetal parameter to assess gestational age and can be used in cases of wrong dates or when other routine parameters are not conclusive or did not accurately predict gestational age for e.g. in cases of hydrocephalus, brachycephaly, dolicocephaly, intrauterine growth restriction, achondroplasia or short limb dwarfism.

Background: The amniotic fluid is fundamental for proper fetal development and growth. Ultrasound visualization of the amniotic fluid permits both subjective and objective estimates of the amniotic fluid. Objective: The objective of this study was to determine the reference values of normal single deepest pocket (SDP) – upper and lower limits, mean SDP and variation of the SDP with gestational age among Igbo women of South-Eastern Nigeria extraction carrying uncomplicated singleton pregnancy. Methodology: This was a prospective cross sectional study involving 400 women carrying uncomplicated singleton pregnancies and who were sure of the date of the first day of their last menstrual period. The single deepest pocket / maximum vertical pool were determined once at presentation at the hospital.. The study was conducted from January 1st to December 31st 2015. The second author carried out all the scanning. The SDP was obtained. Results: The womens’ mean and median ages were the same at 28 years. The gestational age range of the pregnancies was 14-41 weeks. The mean SDP was 5.8cm, while the 5th and 95th percentiles were 3.3cm and 8.5cm respectively. There was no difference in the mean SDP in both term and preterm. There was irregular but continuous rise of mean SDP to a peak of 6.8cm at gestational age of 39 weeks. In conclusion, the participants had a mean SDP of 5.8cm. There was also a positive correlation between SDP and Gestational age. We therefore recommend a longitudinal study to assess perinatal outcome and abnormal amniotic fluid volume among Igbo women of South-Eastern Nigeria. Key words: Single Deepest Pocket, Uncomplicated Singleton Pregnancy, Igbo Women.

Background: Foetal Binocular Distance in Second & Third Trimester of Pregnancy and correlation with Gestation Age is important. Objective: The purpose of the study was to sonographically measure the foetal binocular distance, determine the foetal gestational age & to find out relationship between them in 2nd & 3rd trimester of gestation. Methodology: This cross sectional study was carried out in the department of radiology and imaging Mymensingh Medical College Hospital, Mymensingh and Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period of July 2012 to June 2013. In all the cases BPD, FL, AC, Binocular distance (BD) in cm and gestational age in weeks were measured by USG. Each patient was voluntary enrolled into the study without any specific indication. The measurement was performed only once for each patient. The foetal outer binocular distance was identified in the occipito-transverse or occipito-posterior-foetal positions. With the head in the occipito-posterior position, the transducer was placed in a plane that transected the occiput, orbits, and nasal processes. Measurements were obtained only when the fetal face was directly perpendicular to the uterine wall, since measurements in an oblique plane were considered to be unreliable. Result: The correlation between binocular distance (BD) in cm and gestational age (GA) in wks was calculated. This correlation was highly significant (r = 0. 973; p<0.001).Conclusion:Excellent correlation was found to exist between binocular diameter and gestational age. In the absence of known date of last menstrual period or where fundal height does not agree with dates, these parameters are valuable in estimating the gestational age of the foetus.Journal of Current and Advance Medical Research, 2016;3(1):10-15

Background: Amniocentesis, like other invasive methods, has complications such as abortion, premature rupture - second pregnancy and at 29 weeks of membranes, infection, bleeding, etc. Here, we aimed to study the complications of amniocentesis in pregnant women. Methods: This descriptive cross-sectional study was included 409 women with positive first and second stage screening or required amniocentesis referred to Baghaeipour Clinic in 2017. Data was collected by a pre-prepared questionnaire. Results: The mean age of the patients and gestational age was 33.49 ± 6.51 years and 17.39 ± 1.36  weeks, respectively. 132 patients (32.2%) had a history of abortion. Regarding the frequency of needle passage through the placenta, the results showed that in 369 people (90.2%) the needle did not pass through the placenta and in 40 people (9.8%). The needle has passed through the pair. Regarding the frequency distribution of amniocentesis complications, fetal death in (2.4%), bleeding in (2.2%) and PROM (1.7%) were observed in patients and no case of infection and abortion was observed. In terms of age, gestational age, gestational number, placental location, needle passage, aspirated fluid color, history of abortion and type of delivery, there were no significant differences. Conclusion: In this study the most common complication of amniocentesis was fetal death (2.4%), followed by bleeding and Spotting (2.2%), PROM (1.7%), infection and abortion, respectively.

Purpose. To investigate the association of birth parameters with refractive status in different age groups of Caucasian children.Materials and Methods. This cross-sectional study included 564 eyes of 282 children aged 4 to 17 years. All children underwent complete ophthalmologic examination. The children were divided into three groups according to their refractive status (emmetropia,myopia, and hyperopia), ages (4–7, 8-9, 10–12, and 13–17), and appropriateness for gestational age, respectively.Results. The mean age of the children was9.2±2.8(age range 4–17 years). The mean spheric equivalent was+0.3±1.7(range: (−10.0)–(+10.0) diopters). The mean birth weight and gestational age were2681.1±930.8grams (750–5000 grams) and37.2±3.7weeks (25–42 weeks). According to multinominal logistic regression analysis, children with myopia were more likely to have higher birth weights than emmetropic children (OR: 1.0, 95% CI: 1.000–1.001, andP=0.028). The hypermetropes were found to be significantly small for gestational age between 13 and 17 years of age.Conclusion. Birth weight and appropriateness for gestational age as birth parameters may have an impact on development of all types of refractive errors. The hypermetropic children tended to be small for gestational age.

ABSTRACT Objective To ascertain that acrania can lead to anencephaly Materials and methods We commenced a cross-sectional study for a period of 41 months from 2013 to 2017. During routine ultrasound examination, we observed multiple cases of acrania in second trimester and third trimester. We followed 26 cases who failed to terminate their pregnancies and visited for reexamination. Changes in the brain matter, amniotic fluid volume, and echogenicity of the acrania fetuses were recorded and compared with the previous examination. Development of anencephaly was correlated with maternal age and advancement of gestational age. All the patients were examined transabdominally according to the American Institute of Ultrasound in Medicine (AIUM) guidelines for obstetrical ultrasound. Data were collected from the previous report and recent examination, by evaluating data with the help of IBM Statistical Package for the Social Sciences (SPSS) version 24 package, and the results were summarized. Results Pregnant women with diagnosed acrania fetus visited second time with a lapse of more than 4 weeks and were enrolled with mean age 25.73 ± 8.80. We observed 4 (15.4%) acrania patients developed into anencephaly. Development of anencephaly was observed to be correlated with the advancement of gestational age. It was observed that acrania is more common in below 20 and above 30 age groups. Haziness of amniotic fluid is also observed to be related with acrania. Conclusion Anencephaly could be caused by multiple factors but acrania can lead to anencephaly with continuous exposure of brain matter and meninges to mechanical trauma and chemical activities of the amniotic fluid. Clinical significance To test the hypothesis of acrania to anencephaly and make a roadmap for upcoming researches on association of acrania with physical, environmental, and genetical factors.

Objective To externally validate the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) formula developed from the National Fetal Growth Studies-Singletons and compare with 1984 Hadlock regression in a general obstetrical population. Study Design Cross-sectional study of nonanomalous singletons with a crown-rump length (CRL) and ≥1 additional ultrasound (US) with complete fetal biometrics. CRL established the referent estimated due date to calculate the error at every examination from both formulas. Error was the difference between the CRL-derived gestational age (GA) and each method's predicted GA. Comparisons were also made in three GA intervals: 1 (140/7–206/7), 2 (210/7–286/7), and 3 (≥290/7). Odds ratios evaluated the likelihood of errors outside the prespecified (±) day ranges. Repeated measures analysis of variance and generalized estimating equations controlled multiple US in the same patient. Results A total of 6,043 patients produced 16,904 USs for evaluation. The NICHD formula yielded significantly smaller mean errors in all GA ranges compared with the Hadlock formula (p < 0.01). In interval 3, the NICHD formula had significantly lower odds of discerning examinations outside the prespecified error range (odds ratio: 1.27). Conclusion The NICHD formula is a valid estimate of estimating GA in a general obstetrical population and was superior to the Hadlock formula, most notably in the third trimester.
