INTRODUCTION: To evaluate the performance of first trimester nuchal translucency scan screening among pregnant women in Nigeria.Methods: A prospective observational and questionnaire based study involving 510 pregnant women between 11+0 and 13+6 weeks.Routine counselling and nuchal translucency measurement was conducted using the FMF, London guidelines.

Chorionic villous sampling was done at NT = 2.5 mm or = 95th centile.METHODS: A prospective observational and questionnaire based study involving 510 pregnant women between 11+0 and 13+6 weeks.

Routine counselling stop tool and nuchal translucency measurement was conducted using the FMF, London guidelines.Chorionic villous sampling was done at NT greater than 2.5 mm or greater than 95th centile.

RESULTS: Five hundred and ten out of 542 (94.1%) were analysed, mainly referred by health care workers (87.2%) and from predominantly private facilities (94.

3%).The number of NT scans performed increased in successive years with corresponding decrease in the mean scanning time.Scan was successfully completed at first attempt in (96.

5%), with mean scanning time of 28.3 minutes.Nuchal translucency increases with gestational but not maternal age.

The median and 95th centile at 11+0 week was 1.2mm and 1.7 mm and at 13+6 weeks was 1.

5 mm and 2.2 mm.Using a cut-off of 2.

5 mm or 95th centile, 17 (3.3%) screened positive.Three out of the 17 had invasive testing and 2 (DR = 66.

7%) were confirmed trisomy 21, with a false positive rate of 5.9%.Although majority Course a pied - Homme - Vetements - Chandail - Long sleeves (86.

4%) were willing to have invasive testing, only few (3 or 17.6%) of the high risk group had testing.CONCLUSION: The study demonstrated that NT scan is feasible as a screening tool in pregnancy in Nigeria.

Measures of improving utilization include wider dissemination of information, provision of dedicated NT clinics and manpower training.
