Introduction: Haemorrhages in the third trimester of pregnancy are nowadays a frequent situation that can jeopardize the maternal-fetal prognosis. Given its scale and degree of seriousness, this work was initiated to assess the contribution of ultrasound in its management. Material and Methods: This was a descriptive cross-sectional study with retrospective data collection which took place at the Kalabancoro Reference Health Center from May 1, 2022 to October 31, 2022. Its objective was to study the contribution of ultrasound in the management of haemorrhage in the third trimester of pregnancy. Results: During the study, 154 cases of haemorrhage in the third part of pregnancy out of 2,546 pregnancies were recorded, representing a frequency of 3.4%. The average age of the patients was 27 ± 3.5 years with extremes of 16 and 38 years. Married women were the most represented with 84.4%. Out-of-school women were the most represented, accounting for 63.6% of cases. Multiparous women were the most represented with 39.6% cases. Arterial hypertension was the most common medical history, i.e. 66.6%. Bleeding during pregnancy was the most frequent reason for consultation with 87.6%. Retroplacental hematoma was the predominant etiology, i.e. 67.5%. In utero fetal death was found in 54.5% of cases. Conclusion: The contribution of ultrasound was very important in the therapeutic decision-making. Emergency caesarean section was performed in 66.7% of cases.
