MATERIAL and METHODS: A total of 150 patients with sICH were enrolled, and 44 had early hematoma expansion. According to the selection and exclusion criteria, the study subjects were screened, their NCCT characteristic signs and clinical data were analyzed statistically. The established prediction score was applied to the follow-up study cohort to conduct a pilot study, and the t-test and ROC curve were used to evaluate its predictive ability.

RESULTS: Statistical analysis found that initial hematoma volume, GCS score, and NCCT special signs were independent risk factors for early hematoma expansion after sICH (p<0.05). Thus, a score table was established. Subjects with ?10 were divided into high-risk group, 6-8 comprised the medium-risk group, and ?4 were divided into low-risk group. Among 17 patients with acute sICH, 7 developed early hematoma enlargement. The prediction accuracy was 92.41% in the low-risk group, 98.06% in the medium-risk group, and 84.61% in the high-risk group.

CONCLUSION: This optimized prediction score table based on the special signs of NCCT shows the high prediction accuracy of sICH early hematoma. Keywords : Spontaneous intracerebral hemorrhage, Early hematoma enlargement, Prediction rating table, Computed tomography
