Intrauterine fetal demise (IUFD) and stillbirth are interchangeable terms to describe a fetal death in the second half of pregnancy. IUFD is defined as the delivery of a fetus showing no signs of life as indicated by the absence of heart rate, breathing, umbilical cord pulsation, or voluntary muscle movements. A thorough evaluation of maternal history and risk factors, fetal evaluation involving autopsy and genetic evaluation, and placental pathology should be offered at the time of IUFD diagnosis. Significant counseling should be provided to patients regarding future pregnancies and the risk of recurrence as well as the need for increased antenatal testing and delivery planning in subsequent pregnancies.  This review contains 5 tables, 10 figures and 55 references.  Keywords: fetal kick counts, intrauterine fetal demise (IUFD), management of intrauterine fetal demise, microarray, placental pathology, risk factors for intrauterine fetal demise

Our objective was to determine whether there is an association between hypercoiling of the umbilical cord and placental maturation defect. From a database comprising 1147 cases, containing data on all placentas examined at our institution during the study period we selected all cases with a gestational age of at least 37 weeks that exhibited hypercoiling of the umbilical cord (coiling density above the 90th percentile, n = 42); we also examined 2 matched controls for each case, one with hypocoiling and one with normocoiling. The mean number of syncytiocapillary membranes (SCM) per terminal villus was calculated. Presence of a placental maturation defect was defined as the mean number of SCM below the 10th percentile. Correlations were assessed using Spearman's rho. Relations between dichotomous variables were tested using logistic regression. Mean number of SCM per terminal villus (±standard deviation) was 1.25 ± 0.65. Difference in mean between hypo- and hypercoiled cords was 0.37 (95% confidence interval [CI], 0.07 to 0.67). The correlation coefficient between mean number of SCM and umbilical coiling index (UCI, coils/cm) was −0.28 ( P = 0.002). The odds ratio (OR) for placental maturation defect in presence of hypercoiling was 2.61 (95% CI, 0.75 to 9.12). The OR for fetal death was 132 (95% CI, 13.2 to 1315) in the presence of a placental maturation defect and 5.49 (95% CI, 1.02 to 29.6) in the presence of hypercoiling. The OR for indication of fetal hypoxia/ischemia was 12.3 (95% CI, 3.0 to 50.3) in the presence of a placental maturation defect and 3.2 (95% CI, 0.95 to 10.9) in the presence of hypercoiling. We found a trend toward placental maturation defect in the presence of hypercoiling and an inverse relationship between the mean number of SCM in the terminal villi and the UCI. We confirmed associations between fetal death and both a maturation defect and hypercoiling and found an association between histological indication of fetal hypoxia/ischemia and a placental maturation defect.

ABSTRACT As a nonreassuring fetal status and intrauterine fetal death are often caused by umbilical cord abnormalities, obtaining an ultrasound diagnosis of umbilical cord abnormalities is required for a safe delivery. We believe that the prenatal detection of umbilical cord abnormalities and appropriate management of the delivery improves perinatal morbidity and mortality rates. In the present review, the protocol for ultrasound diagnosis and management of umbilical cord abnormalities, including abnormalities of cord insertion, hypercoiled cord, nuchal cord and fore-lying umbilical cord, is discussed considering current knowledge regarding the physiological and pathological aspects of these umbilical cord abnormalities.

The umbilical cord represents a unique lifeline between the fetus and mother and contains two arteries and one vein wrapped up in Wharton’s jelly with moderate twists. Umbilical coiling abnormalities can result in fetal growth restriction, fetal distress, or intrauterine fetal death. Hypocoiled umbilical cords are associated with intrauterine fetal death (IUFD), fetal growth restriction, fetal distress, low Apgar scores, fetal congenital anomalies, and abnormal insertion of the umbilical cord. Hypercoiled umbilical cords are associated with IUFD, fetal distress, asphyxia, fetal congenital anomalies, and the presence of a single umbilical artery. The aim of this work is to determine if the umbilical Cord coiling index measurement during second trimester ultrasound scan can predict perinatal outcome. Seventy eight healthy uncomplicated pregnant women who regularly attended the antenatal care clinic for antenatal care and to do anomaly ultrasound scan on her baby in 2nd trimester. All participants were informed about the aims and the procedures of the study and signed an informed consent form prior to beginning.

Seventy eight healthy uncomplicated pregnant women who regularly attended the antenatal care clinic for antenatal care and to do anomaly ultrasound scan on her baby in 2nd trimester. All participants were informed about the aims and the procedures of the study and signed an informed consent form prior to beginning. Regular antenatal care visit was done every two weeks till delivery with assessment of perinatal outcomes regarding: gestational age at delivery, fetal monitoring by CTG, method of delivery, meconium staining amniotic fluid or not, examination by apgar score at 1stand 5th minute, birth weight, admission to NICU or not and perinatal death. According to umbilical cord index, of total 78 pregnant women who completed the study 62 (79.2%) were having normal UC coiling, 10 of cases (12.8%) were having hypocoiling and 6 (7.7%) were having hypercoiling. Our results showed that hypo- and hyper-coiling were associated with increased incidence of preterm labor (32-36 weeks) “22.2%and 40% respectively” while normo-coiling was associated with lesser incidence “2%”. Both hypocoiling “10%” and hypercoiling “16.7%”groups showed higher incidence of IUGR when compared with the normocoiling group “1.6%”. APGAR score at minute one was significantly lower in the both hypocoiling and hypercoiling groups than the normocoiling group with p- value: 0.005. While at minute five, there was no significant difference between the three groups of the study. Conclusion: The abnormal umbilical coiling index “< 10th percentile or > 90th percentile” is associated with adverse perinatal outcomes. Therefore, early evaluation on Umbilical cord Index in the 2nd trimester can identify fetuses who are at risk and thus help in further management.are visit was done every two weeks till delivery with assessment of perinatal outcomes regarding: gestational age at delivery, fetal monitoring by CTG, method of delivery, meconium staining amniotic fluid or not, examination by apgar score at 1stand 5th minute, birth weight, admission to NICU or not and perinatal death.
