Abstract:
To explore the correlation between hematoma expansion within 24 hours of hypertensive intracerebral hemorrhage and signs on nonenhanced computed tomography(NECT). Methods The clinical data and CT images of 185 patients with hypertensive intracerebral hemorrhage were retrospectively analyzed.The differences in CT parameters were compared between the expansion group and the unexpanded group.Binary logistic regression analysis was performed on the indicators with statistical significance between the two groups to identify the potential correlation between CT parameters and hematoma expansion.The roles of blend sign,lobulation sign,and black hole sign in predicting early hematoma expansion were assessed. Results The CT quantitative data including initial volume,maximum diameter,minimum diameter,maximum CT value,mean CT value,difference between maximum diameter and minimum diameter showed no significant difference between these two group(all >0.05).CT qualitative data including blend sign,lobulation sign,and black hole sign were significantly different(<0.05)but the differences became not significant after the hematoma broke into the ventricles.Binary logistic regression analysis showed that blend sign,lobulation sign,and black hole sign were independent risk factors for early hematoma expansion,with sensitivity,specificity,positive predictive value,and negative predictive value of the combined signs and the early hematoma expansion calculated by the four-fold table method being 78.4%,59.0%,42.1%,and 87.8%,respectively,and the Youden index was 0.374.Its Youden index was closer to 1 than the blend sign,the black hole sign,and the lobulation sign. Conclusion The blend sign,lobulation sign,and black hole sign in NECT can be used to predict hematoma expansion within 24 hours after hypertensive cerebral hemorrhage.
