Introduction: Placenta previa is an obstetric emergency that can be life-threatening for both mother and foetus. Despite the progress made in diagnosis and treatment, it continues to be feared by obstetricians because of high maternal and perinatal mortality and increased morbidity. This study aims to investigate the diagnostic, therapeutic and prognostic aspects of placenta previa at the Sourô Sanou University Hospital in Bobo-Dioulasso. Method: This was a descriptive cross-sectional study with retrospective data collection from January 1, 2016 to December 31, 2018. Included were 142 pregnant women admitted to the maternity ward of the Sourô Sanou University Hospital (CHUSS) and diagnosed with placenta previa during pregnancy, labor, or in the postpartum period. Result: The frequency of placenta previa was 0.89%; the average age of patients was 28.51 years with extremes of 16 and 44 years. The multigestations represented 28.17% and the pauciparous 31.69%. Patients with a uterine scar represented 15.49%. Ultrasound diagnosis was made in 38 patients (26.76%). Placenta previa was recovered in 56.34% of cases. Patients with severe anaemia were 28.87%, and 57.04% of the anaemic cases received blood transfusion. Caesarean section was performed in 93.66% of patients. Four maternal deaths (2.81%) and 30 stillbirths (27.02%) were reported. Conclusion: Placenta previa remains a fairly frequent pathology with a nonnegligible lethality rate and perinatal mortality in the maternity ward of the
