État des lieux des échographies obstétricales au service d’imagerie du Centre Hospitalier Universitaire Bogodogo du 1(er) janvier 2016 au 31 décembre 2018

Obstetric ultrasound performed according to standards from its prescription to the report is a guarantee of quality. The aim of our study was to take stock of obstetrical ultrasounds in order to make rational the ultrasound follow-ups of pregnancy. This was a descriptive cross-sectional study with retrospective data collection through the reports of obstetrical ultrasounds performed from the 1(st) January 2016 to 31(st) December 2018. Of the 13,487 ultrasounds in the study period, 2,355 were obstetric ultrasounds, constituting 1746% of the ultrasound activity. The mean gestational age was 27.54 years (± 6.19). The CHU Bogodogo was the requesting structure for 86.88%. Paramedics were prescribers in 66.47%. Third trimester ultrasounds made up 57.06%. Gestational age in 12.99% was greater than 37 weeks while in 66.37% gestational age was greater than 24 weeks. Prenatal follow-up was indicated in 54.48%. Pregnancies were progressive in 97.49%. Twin pregnancies represent 2.72% and ultrasound pathological pregnancies 11.80%. Obstetric Doppler was performed in 2.12% with pre-eclampsia as the main indication (52%). There was 1.18% malformation with nervous system involvement in 60.71%. Through this inventory, the training of prescribers of obstetric ultrasound appears essential. The establishment of an observatory of obstetric ultrasound practices would be an asset for the quality of these medical examinations.
