<strong>Abstract</strong> <strong>Introduction</strong><strong>:</strong> Umbilical cord is lifeline connecting mother & fetus. About 96% of the umbilical cords have coils. Coiling can be Normocoiled, Hypocoiled or hypercoiled. Adverse perinatal outcome is likely to be associated with abnormal coiling. Hence, this study was an attempt to find the correlation of the abnormal postnatal umbilical coiling index and the perinatal outcome. <strong>Methods:</strong> This study was a cross sectional, non-interventional, observational study, conducted at the department of Obstetrics and Gynaecology

Abstract:

Background: The umbilical cord has pivotal role in the development, well-being, and survival of fetus and is vulnerable to kinking, torsion, and compression affecting perinatal outcome adversely. Aims and Objectives: This study was aimed to correlate the umbilical cord index measured antenatally using ultrasonography with that of the umbilical cord index measured postnatally and the association of this index with adverse fetal outcomes. Materials and Methods: This prospective cohort study was conducted on 124 antenatal cases of age group 18–35 years with term gestation with singleton pregnancy

Background: To correlate the perinatal outcome by noting the umbilical coiling index.Methods: The umbilical cords of the babies born to 500 women, who delivered either vaginally or by lower segment caesarean section, were examined and umbilical coiling index was calculated.Results: There was significant correlation (p value 0.003) between. Hypercoiling (UCI >90th percentile) is associated with IUGR. Hypocoiling (UCI <10th percentile) is associated with: - Meconium staining liquor, high LSCS rates, low Apgar score <7 at 1 min and at 5 min respectively and NICU admissions of babies.Conc

Abstract:

The normal umbilical cord coil index is one coil/5 cm, i.e., 0.2 ±0.1 coils completed per cm. We report the frequency and clinical correlations of abnormally coiled cords among 1329 cases referred to our placental pathology services. Twenty-one percent of cords were over-coiled and 13% were undercoiled. Abnormal cord coiling was seen at all gestational ages. Principal clinical correlations found in overcoiled cords were fetal demise (37%), fetal intolerance to labor (14%), intrauterine growth retardation (10%), and chorioamnionitis (10%). For undercoiled cords, the frequencies of these adverse

Abstract:

The abnormal umbilical cord coiling pattern affects the well-being of the newborn in different ways. Moreover the differentiation of mast cell according to these patterns may also varies. The objective: to investigate the detection and enumeration of mast cells in different patterns in human coiling cords in order to explore their effect on the newborn baby health.Materials and methods. Umbilical cord samples were collected from 105 healthy pregnant women. The cords were collected immediately after labor and kept in formalin (10%), according to coil type. Three major categories of umbilical co

Abstract:

<strong>Background:</strong> The umbilical cord forms connecting link between the fetus and placenta through which the fetal blood flows to and from the placenta. Its three blood vessels pass along the length of the cord in a coiled or helical fashion (spiral course). The aim of the study was to evaluate umbilical cord coiling abnormalities and determine its relationship with maternal and perinatal outcomes. <strong>Material and methods:</strong> The study included 190 patients divided into 2 groups: L1 – 95 patients with UC abnormalities and L0 – 95 with normal UC.
