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 fukudadenshi 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.
