摘　　要：目的探讨CT血管造影(CTA)对颅内动脉瘤破裂的预测价值。方法对38例颅内动脉瘤患者进行CTA扫描诊断,以数字减影血管造影(DSA)、CTA确诊为动脉瘤破裂者设为破裂组,测量动脉瘤的长度、瘤颈宽度,计算动脉瘤体颈比(AR)和入射夹角,并对动脉瘤破裂的CTA相关参数进行回归分析。结果 CTA诊断颅内动脉瘤破裂的灵敏度为86.7%、特异度为93.1%、准确性为90.9%。破裂组和未破裂组患者瘤体长度、瘤颈宽度、AR值、入射夹角比较,差异均有统计学意义(P<0.05)。瘤体长度>3.65mm、瘤颈宽度>3.35mm、AR值>1.14、入射夹角>110.5°为动脉瘤发生破裂的危险因素。结论 CTA能准确诊断颅内动脉瘤破裂,通过瘤体长度、高度、AR值及入射夹角可准确评估动脉瘤破裂风险,早期预测动脉瘤破裂。Objective To investigate the predictive value of CT angiography （CTA） for ruptured intracranial aneurysms. Methods 38 cases of patients with intracranial aneurysms CTA scan diagnostics to digital subtraction angiography （ DSA）, CTA diagnosis of ruptured aneurysm rupture set group, who set unruptured unruptured group, measure the length of the aneurysm, aneurysm neck width, neck artery aneurysm calculated ratio （AR）, the incident angle, and the CTA aneurysm rupture parameters regression analysis. Results CTA diagnosis of intracranial aneurysm rupture sensitivity was 86. 7%, specificity was 93. 1%, and accuracy was 90. 9% ; tumor length, width of the aneurysm neck, AR, the incident angle between two group showed statistically significant （ P 〈 0. 05 ） ; tumor length 〉 3.65 mm, aneurysm neck width 〉 3.35 mm, AR values 〉 1.14, the incident angle 〉 110. 5° were risk factors for aneurysm rupture. Conclusion CTA can accurately diagnose intracranial aneurysm rupture, and through the tumor length, height, AR value and accurate assessment of the incident angle of aneurysm rupture risk, early prediction of aneurysm rupture.
