Characterization of Fetal Nuchal Translucency Thickness using Ultrasonography

Abstract

This is a crossectional descriptive study which was done during june- 2018 to December

-2018 and was carried out in( Elsaudi hospital and Bashaier universal hospital) Khartoum-Sudan.

The study discusses the characterization of fetal nuchal translucency thickness in

Khartoum state. Atotal of 60 pregnant women were selected with age range 18-40 year

and gestational age fetus range 11-14 weeks.any pregnant women with fetus gestational

age less or more than this age were excluded. All of them were subjected to be examined

by ultrasound scanning using fukuda denshi and sonoscape scanners with 3.5 megahertz

probe. Transabdominal scanning were performed for all 60 pregnant women to measure

nuchal translucency thickness and different other variables which were gestational age ,

crown rump length and amniotic fluid , data was collected using data collection sheet

and for data analysis ,statistical package for social sciences (spss) was used.

significance tests and correlation between variables was done. The study showed that the

age range of women under study was 18-40 years with mean age 28.47 years. The total

of them were 1-9 gravida with mean 3.32. crown rump length range 32.6-70.5

millimeter with mean 52.118 millimeter. gestational age took at 11.00 -14.00 week with

mean 12.0738 week . nuchal translucency thickness range were 1.1-2.6 millimeter with

mean1.795 millimeter. The study found that there was weak linear association between

gestational age, crown rump length ,gravida and nuchal translucency, R2= o.02 and no

significant correlation was found between them when

P>0.05. The study found that there was weak linear association between nuchal

translucency thickness and maternal age when R2=0.12( for every year nuchal

translucency increased o.17 millimeter), but there was moderate significant correlation

between maternal age and nuchal translucency when P < 0.01 and R =0.35.

in addition to that amniotic fluid the study found that, 100 percent have average

amniotic fluid ,so no relation between and nuchal translucency. The study recommended

that Pregnant women in different ages must do ultrasound scanning routinely and

nuchal translucency thickness should be taken as a routine measurement for all pregnant

women with pregnancy gestational age 11-14 weeks to exclude any chromosomal

abnormalties ,also more care and followup should be done for pregnant women in

advance ages above 35 years.

Lastly, the study put recommendation for further studies to be carried out in this field on

many aspects such as increasing the sample volume or by taking big sample that concentrate on pregnant women in advance age above 35 years.
