ABSTRACTObjectives: Intrauterine growth restriction (IUGR) is one of the common conditions that interfere with the growth of the fetus accounting for 10-15%of pregnant woman. Literature explores a wide range of incidence of perinatal complication including mortality among IUGR pregnancies. Limiteddata available on these complications confined to coastal Karnataka and its association with abnormal arterial Doppler flow pattern. To study theperinatal complications associated with IUGR pregnancies and its prevalence in comparison to healthy controls of comparable gestational age.Methods: This cohort study screened 53 IUGR fetuses by an antenatal scan at gestational age of 27 weeks or more. The diagnosis of IUGR was madeaccording to established criteria from SOGC clinical practice guidelines August 2013. The data also included 48 appropriate for gestational age fetuseswith healthy mothers with the comparable gestational week. Experienced cardiac sonographer and gynecologist performed fetal echocardiography(ECHO) using Vivid 7, GE health-care system ECHO machine with the convex transducer of frequency 1.7-2.4 MHz. The study was conducted at southIndian tertiary care center.Results: This study included 53 IUGR cases and 48 non-IUGR controls. The mean age was 27±4.37 and 26.88±3.14 years in IUGR and non-IUGRgroups, respectively. Fetal Doppler study variables showed a significant decrease in peak aortic velocity and velocity time integral which was notevident on other valves, though mitral antegrade flow during atrial contraction was found to be lower among IUGR group. In two-dimensional chamberquantification of IUGR group revealed significant increase in pulmonary artery dimension, right ventricular (RV) dimension and RV thickness than thecontrol group (p<0.05). The anthropometric parameters such as weight and length; abdomen circumference was significantly lower in IUGR group,whereas head circumference found to be more in IUGR group (p<0.001). The gestational weeks at delivery was significantly different among twogroups with IUGR group depicting the early delivery group. p<0.001(35.58±2.92 and 38.5±0.96 in IUGR and non-IUGR groups, respectively). IUGRgroup also had prolonged neonatal intensive care unit stay when compared to controls (p<0.001).Conclusions: IUGR carries profound course in altered Doppler indices and cardiac function which explore its prediction on mortality and adverseperinatal outcome. This study showed significant perinatal mortality accounting for 5.6% among IUGR cases when compared to normal. Althoughtissue Doppler indices show normal variants, IUGR possesses significant adverse perinatal outcome, however with lesser incidence compared tosevere form of IUGR subsets who show altered tissue annular velocities.Keywords: Intrauterine growth restriction, Echocardiography, Doppler, Perinatal.

Preeclampsia and Intrauterine growth restriction (IUGR) remains as the important causes for the neonatal and maternal complications leading to even death in some cases. Uterine artery Doppler USG can be done transvaginally or trans abdominal and performed in the 1st or 2nd trimester of the pregnancy to detect these complications Doppler waveform suggested the high vascular resistance to blood flow. In our present study, we conclude uterine artery Doppler indices as prognostic procedure for the preeclampsia and intrauterine growth restriction. A cross-sectional survey design with convenient sampling technique was used. Mixture of standardized and self-modified structured questionnaire was undertaken to determine the indices of pre eclampsia and IUGR by uterine artery. The data was collected from Bahria International Hospital, Lahore during the period of 9 months. This study was included 162 pregnant females with identification of the main uterine artery on a longitudinal scan lateral to the uterus.  Initial diastolic notch of right and left side of the uterine artery waveforms was recorded. At every antenatal checkup, urine was tested for protein and blood pressure readings were taken to identify preeclampsia. Further analysis was done dividing patients as normotensive and those patients developing hypertension after 30 weeks of gestation. After delivery neonates observed for IUGR by head circumference and body weight. The study was concluded that from the total sample size of 162 pregnant females who undergoes uterine artery Doppler, 34% females shows diastolic notch and almost all of these later diagnosed with preeclampsia and 19.8% deliver babies with IUGR. So, based on the study, we have concluded that uterine artery Doppler is helpful to provide diagnosis of preeclampsia and IUGR in early pregnancy.

Abstract Background Placental elasticity varies in different diseases. Our objective was to evaluate placental elasticity using point shear wave elastography (pSWE) in pregnancies with intrauterine growth restriction (IUGR). Methods A total of 66 pregnant women with IUGR and 81 healthy pregnant women were enrolled. Placental elasticity was measured using the transabdominal pSWE method. Ten measurements were made, and the mean was accepted as the mean placental elasticity value in each case. The results for IUGR pregnancies and controls were compared. Results The mean pSWE values were significantly higher in pregnancies with IUGR, which means that women with IUGR have stiffer placentas (P < 0.001). Furthermore, the pSWE values were significantly and positively correlated with Doppler indices and adverse perinatal outcomes. Conclusion The pregnancies with IUGR had stiffer placentas than the healthy controls. The utilization of pSWE for placental elasticity may be useful in the diagnosis and management of IUGR as a supplement to the existing ultrasonography methods.

Biomarker Analysis

IntroductionPre-eclampsia (PE) and intrauterine growth restriction (IUGR) are two major pregnancy complications, related to chronic uteroplacental hypoperfusion. Nowadays, there is no screening or diagnostic test for uteroplacental vascularisation deficiency in pregnant women. Since 2004, 3 three-imensional power Doppler (3DPD) angiography has been used for the evaluation of uteroplacental vascularisation and three vascular indices are usually calculated: Vascularisation Index (VI), Flow Index (FI) and vascularisation-FI (VFI). A high intraobserver and interobserver reproducibility and a potential interest for placental function study were reported by our team and others.The main objective of our study is to determine differences in 3DPD indices at first trimester between pregnancies defined at their outcome as uncomplicated pregnancy, PE (mild and severe) and IUGR in nulliparous women.Methods and analysisThis is a national multicentre prospective cohort study conducted in four French maternity units. We expect to include 2200 women in a period of 36 months. The nulliparous pregnant women will be recruited during their first trimester consultation (11–13+6 gestation week (GW)).The 3DPD and uterine artery Doppler acquisition will be included in the current routine 11–13+6 GW ultrasound. Also, additional blood samples will be taken for biomarker analysis (PAPP-A and P1GF) and biological collection. Uteroplacental VIs (FI and VFI) will be measured. For each subgroup (uncomplicated pregnancy, PE and IUGR), mean values in 3DPD indices will be computed and compared using a pairwise t test with a Bonferroni correction p value adjustment.Ethics and disseminationThe study was approved by the French Ethics Committee, the Comité de Protection des Personnes SUD MEDITERRANEE IV on 13 February 2018 with reference number 17 12 03. The results of this study will be published in a peer-reviewed journal and will be presented at relevant conferences.Trial registration numberNCT03342014; Pre-results. PHRCN-16-0567.
