Background: Initial haematoma volume is one of the strongest predictors of prognosis in haemorrhagic stroke. The aim of this study was to analyse the factors associated with haematoma volume in haemorrhagic stroke at the Sour？ Sanou University Hospital in Bobo-Dioulasso. Methods: This was a prospective cross-sectional study of patients admitted from 16 July to 15 October 2022 for haemorrhagic stroke. Data were analysed using STATA 17.0 software. Results: The study included 60 patients. Hypertension was the main cardiovascular risk factor (83.3%). The sex ratio was 1.2. The mean age was 58.1 ± 15.6 years. The mean arterial pressure at admission was 179.4 ± 31.8 mmHg for systolic and 112.7 ± 26.2 mmHg for diastolic. The NIHSS score at admission was greater than 15 in 27 (45%) patients. The mean length of hospital stay was 7.3 ± 9.7 days. The mean haematoma volume was 29.97 ± 31.35 cc with extremes ranging from 0.2 to 158 cc. Factors associated with haematoma volume greater than 60 mL were diastolic blood pressure (p = 0.008; OR = 1.05; 95% CI: 1.01 - 1.10) for each unit increase in diastolic blood pressure and NIHSS score (p = 0.02; OR = 1.11; 95% CI: 1.01 - 1.20) for each unit increase in NIHSS score. Conclusion: This study shows that the NIHSS score and diastolic blood pressure were the independent factors associated with haematoma volume. These therapeutic targets should make it possible to avoid expansion of haematoma volume and improve the prognosis of haemorrhagic stroke.
