“…Happily, this forms the bulk of our findings constituting 42.5% of our studied population (Table 2). This is lower than 81.3% of single uncomplicated viable pregnancy diagnosis seen in another study [4]. Their higher value may be because of their larger sample size which doubled our studied sample.…”

“…It has rapidly replaced all other techniques used to study normal human development especially in the first trimester [ 3 ].The advent of high-resolution trans-vaginal ultrasound (TVS) has corroborated trans-abdominal ultrasonography (TAS) and went further to revolutionize our understanding of the pathophysiology and management of pregnancy [ 3 ]. First trimester pregnancy is defined as twelve weeks after the last menstrual period [ 4 ]. It is known to be the important period of organogenesis but could be fraught with high complication rate [ 4 , 5 ].…”

IntroductionFirst trimester pregnancy is defined as twelve weeks after the last menstrual period. Ultrasonography has revolutionized validation and management of first trimester pregnancies. The aim was to analyze ultrasonographic findings of first trimester pregnancies in University of Uyo teaching hospital (UUTH), Uyo, Nigeria.MethodsThe departmental ultrasonographic records of pregnant women who were referred to Radiology department of UUTH, Uyo, Nigeria. For ultrasound scans were retrospectively reviewed. The period under consideration was from 8th January 2013 to 8th February, 2016. Demographic data and ultrasonographic parameters of first trimester pregnancies like gestational sacs were recorded. Data were statistically analyzed using SPSS Chicago 13. Exclusion criterion included incomplete data and acyesis despite positive βhCG test.Results26.4% (n-645) of the 2438 pregnant women who underwent obstetric ultrasonography had first trimester ultrasonography during the studied period. The peak frequency was seen in the 20-29 age range with 52.2% (n-337) and followed by 30-39 age range with 41.7% (n-269). The commonest first trimester ultrasound findings was viable pregnancy with 42.5% (n-274), followed by incomplete miscarriage with 34.3% (n-221). The least finding was trophoblastic pregnancies 0.3% (n-2). The earliest age at which normal viable pregnancy was diagnosed in this study was 5weeks 5days from the last menstrual period. Only 2.19% (n-6) of the normal viable pregnancies were multiple pregnancies and they were all twins. The highest number of referrals to Radiology Department for first trimester ultrasonography was from accident and emergency unit with 34.42% (n-222) while antenatal clinic referral was only 16.12% (n-104).ConclusionThe commonest first trimester’s obstetric ultrasonographic findings in Uyo, Nigeria are viable pregnancies and are predominantly single gestation. The earliest age of ultasonographic pregnancy detection in Uyo is 5week 5days and peak maternal age is second and third decades.

“…The localization, thickness, and structure of the chorion were also estimated. 12,17,18 Fetometry, measurements of the quantity of amniotic fluid present, and placentometry were performed by ultrasound during the second trimester. The echostructure, location, and thickness of the placenta as well as the state of the intervillous space, the presence of calcification, and the presence of additional placental lobes were described.…”

An excess of maternal androgen adversely affects the implan tation process and contributes to uterine circulatory disturbances and myometrium vessel sclerosis. Placental insufficiency is typi cally diagnosed at the end of the second trimester of pregnancy or at the beginning of the third trimester, when the treatment is not effective.Many researchers have attempted to use early sonographic diagnostics to identify placental failure in various pathological states. Nevertheless, the peculiarities of the formation of the fetal-placental complex during the first and second trimesters are still undefined. In this study, we traced the process of placental formation under conditions of excess maternal androgen using ultrasound and Dopplerometry. Morphological examinations of the сhorion and placental tissue were undertaken to сompare any changes.Unfavorable chorion locations, heterogeneous chorion tis sue structures, and marginal sinus dilatations were revealed by ultrasound. According to a Dopplerometric investigation, a statistically significant increase in peripheral vessel resistance in cases of hyperandrogenism was identified compared with healthy pregnancies. The negative influence of hyperandrogenism on placental formation was confirmed by morphologi cal data (including the presence of immature decidual cells, defec tive villi that covered the epithelium, and the dissociative development of cotyledons).

Background: The purpose of the study is to know the effect of abnormal yolk sac, abnormal gestational sac and abnormal embryonic heart rate on outcome of pregnancy in the tertiary care centre of Chhattisgarh.Methods: This prospective observational study included 50 pregnant females between 6-9 weeks gestation with singleton pregnancy attending antenatal clinic in a tertiary medical institution. Transvaginal sonography was carried out to quantify yolk sac characteristics. Abnormal yolk sac was defined according to Nyberg criteria.Results: Out of 50 cases, 25 cases had abnormal yolk sac, 23 cases had abnormal gestational sac and 22 cases had abnormal embryonic heart rate and heart rate was absent in 23 cases. Out of 50 cases, 32 got aborted and rest 18 cases had ongoing pregnancy beyond 20 weeks. Normal yolk sac diameter (YSD) (2-5 mm) showed 72.2% sensitivity, 62.5% specificity, 52% positive predictive value and 80% negative predictive value in predicting pregnancy outcome. Gestational sac diameter had 66.66% sensitivity, 53.12% specificity, 44.44% PPV and 73.91% NPV and for EHR had 22.22% sensitivity, 96.87% specificity, 80% PPV and 68.88% NPV.Conclusions: The embryos with abnormal YSD are highly associated with poor pregnancy outcome with good sensitivity and NPV. Present study indicates that the yolk sac measurement is reliable prognostic factor in predicting 1st trimester pregnancy outcome.
