AbstractObjective: Describe the profile of the origin of the supra-aortic trunks at the Niamey general reference hospital.
Material and Methods: Retrospective and prospective study on the anatomical variants of origin of ASD, lasting 18 months from November 1, 2019 to April 30, 2021 in the SRIM of the HGR of Niamey. It was descriptive and analytical and included patients of all ages who had performed a CT examination of the chest with injection of iodinated contrast product. The original anatomical variants of the supra-aortic trunks had been described according to the classification of Natsis et al.
Results: the study population was 428 patients. The male gender represented 55.84% (n=239) with an M/F sex ratio of 1.26. The average age of the patients was 51.86±16.68 years with extremes of 4 years and 98 years. The age group >60 years was the most represented with 34.58% (n=148) of patients. The pediatric population represented 0.70% (n=3) of the total population.
Conclusion: Knowledge of anatomical variants is important in order to distinguish them from pathological conditions. More than 20% of the population studied presented an anatomical variant of the origin of the supra-aortic trunks. This is important preliminary data in the field of interventional radiology in our context.
