RESUMO
OBJECTIVE: Improvement in prenatal diagnosis of Down syndrome imposes to sonographers to realize good quality nuchal translucency measurements, which can be used for assessment of combined risk. The aim of our study was to evaluate a training program of 109 sonographers for measuring nuchal translucency and scoring their own image. STUDY DESIGN: After a proximity training program, trainees submitted 20 images scored by themselves with Herman image-scoring method. All images were reviewed by two experts. RESULTS: One hundred and nine sonographers have accomplished the training program (87.3%), collecting 2162 images. After reviewing, the mean score was 6.8+/-1.8. The rate of inacceptable scan (score< or =3) was in 6.0%. On the other hand, 48.1% of scans were excellent (score> or =8). Only 6.5% of scores were discordant for at least three points between self-scoring and reviewing. After the fourth scan, there was no significant scoring difference between self-scoring and reviewing. Finally, 84% of trainees were very satisfied of this program. CONCLUSION: As part of HAS evaluation of practitioners practices, it is possible to realize proximity training program for measuring nuchal translucency. Learning curve seems to be fast. Good handling of Herman scoring method by sonographers allows their accreditation after this kind of training program.

Echographic changes in ectopic pregnancy can affect uterus, annexes and cul-de-sac of Douglas. They are inconstant and quite variable according to the anatomic stage. Echographic aspects of 50 proved ectopic pregnancies and their frequency are reported. The echographic signs are then evaluated according to their viability and possible errors (differential diagnosis).
