Aspects tomodensitométriques des accidents vasculaires cérébraux diagnostiqués chez 500 patients reçus pour une suspicion d’AVC dans le service d’imagerie médicale et radiologie interventionnelle du Centre Hospitalier Universitaire de Bogodogo

Introduction: Stroke is a major public health problem, and brain computed tomography (CT) remains the first-line investigation to distinguish ischaemic from haemorrhagic stroke. This study aimed to describe the CT findings of stroke at Bogodogo University Hospital (Ouagadougou, Burkina Faso) and their associated factors. Methods: We conducted a prospective, descriptive and analytical cross-sectional study from 5 February to 4 September 2023 among patients aged 18 years or older who underwent brain CT for suspected stroke. Associated factors were assessed by binary logistic regression. Results: Among 500 patients (mean age: 57.07 ± 16.4 years; sex ratio: 1.36), hypertension was the main medical history (51.6%). Only 5% of patients presented within 3 hours, and 92.4% underwent CT within 24 hours of admission. CT confirmed stroke in 72% of cases (246 ischaemic and 113 haemorrhagic strokes) and was normal in 25.6%. The middle cerebral artery was the most frequently involved territory (80.6% of ischaemic strokes with a specified territory). In multivariable analysis, male sex was inversely associated with haemorrhagic stroke (aOR = 0.38; 95% CI: 0.19–0.75); no independent factor was associated with ischaemic stroke. Conclusion: Ischaemic stroke predominates and pre-hospital delay remains long. A stroke unit and access to thrombolysis are needed.
