Objective: to search for the relationship between the transverse diameter of the cerebellum and gestational age in the Burkinabe fetus.
RESUME
Methodology: descriptive cross-sectional study carried out from November 2016 to December 2018. The population consisted of Burkinabe pregnant women who had consulted for a fetal ultrasound. Inclusive monofetal pregnancies, with no obvious fetal or annexal morphological abnormalities, no known maternal pathology, with a known date of last menstrual period. The data collected were maternal age, gestational age, and transverse diameter of the cerebellum.
Results: We included 537 cases during the study period. The average age of gestants was 28.89 years. Mean gestational age 29.19 years. The average transverse diameter of the cerebellum was 36.44 ± 10.98 mm, with extremes of 17 and 59 mm. There was a linear increase in the transverse diameter of the cerebellum with gestational age. The Pearson correlation coefficient was measured at 0.96.
Conclusion: The measurement of the transverse diameter of the cerebellum can be used for the dating of even late pregnancies in our context.
Objectif : rechercher la relation entre le diamètre transversal du cervelet et l’âge gestationnel chez le fœtus burkinabè.
Méthodologie : étude transversale descriptive réalisée de novembre 2016 à décembre 2018. La population était constituée de patientes burkinabè, ayant consulté pour une échographie fœtale. Ont été incluses les grossesses mono fœtales évolutives, sans anomalie morphologique fœtale ou annexielle évidente, sans pathologie maternelle connue, avec une date de dernières règles connue. Les données recueillies étaient l’âge maternel, l’âge gestationnel et la mesure du diamètre transversal du cervelet.
Résultats : Nous avons colligé 537 cas durant la période de l’étude. L’âge moyen des gestantes était de 28,89 ans. L’âge gestationnel moyen de 29,19 ans. Le diamètre transversal moyen du cervelet était de 36,44 ± 10,98 mm, avec des extrêmes de 17 et 59 mm. Il existait une augmentation linéaire du diamètre transversal du cervelet avec l’âge gestationnel. Le coefficient de corrélation de Pearson était mesuré à 0,96.
Conclusion : La mesure du diamètre transversal du cervelet peut être utilisée pour la datation des grossesses même tardives dans notre contexte.
