Abstract：Objective To explore the application value of CTA (Computerized Tomography Angiography) spot signs in prediction of hematoma expansion in patients with acute hypertensive ICH (Intra-Cerebral Hemorrhage). Methods Altogether 76 ICH patients who had been examined in the hospital between January 2013 to December 2014 were selected. All the patients underwent plain CT scanning and CTA when they were hospitalized; then were re-examined by plain CT scanning 24 hours after they were treated. CTA spot signs were utilized to predict hematoma expansion in patients with acute hypertensive ICH and record the sensitivity, specificity, accuracy, positive and negative prediction values. Additionally, the hematoma volume and morphology were analyzed statistically. Results With the deployment of CTA spot signs, the sensitivity, specificity, accuracy, positive and negative prediction values of hematoma expansion were 89.7% (26/29), 93.6% (44/47), 92.1% (70/76), 89.7% (26/29) and 93.6% (44/47). Statistically significant differences were seen in the hematoma volume between Positive Group and Negative Group of CTA spot signs during preliminary examinations and re-examinations (t=5.338, P=0.002; t=7.019, P=0.000). In Positive Group of CTA spot signs, there were 18 cases with regular hematoma morphology and 11 cases with irregular hematoma morphology. While, in Negative Group, there were 42 cases with regular hematoma morphology and 5 cases with irregular hematoma morphology. Statistically significant differences existed between two groups (P<0.05). Conclusion CTA spot signs revealed high effectiveness in prediction of hematoma expansion in patients with ICH, which could be used as an independent predictor.
