Histological Study of Umbilical Cord at Different Stages of Gestation
THE EGYPTIAN JOURNAL OF EXPERIMENTAL BIOLOGY, 2013
The umbil ical cord is the l ifel ine between the foetus and placenta. It is formed by the fi fth week of development and it functions throughout pregnancy to protect the vessels that travel between the foetus and the placenta. In the present study, 60 term placenta were studied. Out of these 28 were of female and 33 of male babies from healthy looking mothers aged between 25 35 years and the parity from one to five. All cords obtained were of normal vaginal deliveries and aborted foetuses. For l ight microscopy, two cm. of t issue was taken from each cord and fixed in 10% formalin for one week. Grossly the attachments of umbil ical cord to the placenta were observed which showed that the eccentric site of insertion was 64.99%, the central insertion 28.33% and the marginal insertion 6.66% from the total observed placenta. The tunica intimae consist of a single continuous wavy layer of small oval or rounded shaped, which bulges into the lumen of arteries. A thick tunica medium which ...
A Study of Microscopic Abnormalities of Human Umbilical Cord
IAHS Medical Journal
Background: Umbilical cord act ascable that links the fetus to the placenta. Fetal wellbeing depends much on the normal structure andfunction of umbilical cord. Blood vessels in it connect the uterine vasculature and the fetal vascular tree and are essential part of fetal circulation. A number of structural abnormalities, macroscopic and microscopic, can affect the umbilical cord and the ultimate effect is disturbance of the lifeline & derangement of blood flow to the fetus. Hence, structural changes of umbilical cord have been found to be a marker of intrauterine complications of fetus. The aim of the study is to find out the microscopic abnormalities of human umbilical cord in normal pregnancies. Materials and methods: A descriptive cross sectional study was done in the Department of Anatomy, Chittagong Medical College on 60 human umbilical cord sample from August 2012 to January 2013. Results: Among the 60 samples endothelial erosion was found in 11.7% cases, extravasation of blo...
Objectives:-To evaluate the perinatal outcome with the abnormal umbilical cord thickness, cross sectional area and index. Study Design:-This prospective study was carried out in Benha university hospital faculty of medicine Obs and Gyna department. Two hundred women were in active labour at term gestations, and irrespective of their parities, they were having singleton pregnancies with live babies , were delivered by vaginal root Umbilical cord coiling index , thickness and cross sectional area were calculated and were correlated with various perinatal parameters like birth weight, meconium stained liquor, Apgar score, ponderal index and foetal growth restriction. Results:-There was a significant correlation between the hypercoiled cords (UCI >90 th percentile) and meconium staining (p value < 0.001) and Apgar score at 1 min of <4 and at 5 min of <7 (p value 0.001) and there was a significant correlation between hypocoiling and meconium stainging p<0.001 FBW and apgar score at 1<4 and at 5 mint >7 (P–value 0.001). Conclusion:-Hypercoiled cords or UCI which was > 90 th percentile was associated with meconium staining and low apgarscore at one and five minute. While hypocoiled cord or UCI which was <10th percentile was associated with low birth weight, meconium staining and apgerscore at 1 min <4 and at 5 min of <7.
