目的探讨64排螺旋CT血管造影(CTA)对颅内动脉瘤早期诊断的临床意义. 方法选取疑似颅内动脉瘤的蛛网膜下腔出血患者42例,在病情允许条件下首先进行64排螺旋CTA检查,随后进行DSA检查,采用自身配对四格表卡方检验,分析CTA与DSA检查结果的差异性. 结果 39例患者经CTA检查证实为颅内动脉瘤(瘤体直径2～26mm),1例患者CTA检查疑似动脉瘤,1例患者CTA检查阴性.41例患者经DSA检查发现动脉瘤,1例患者DSA检查阴性.CTA与DSA动脉瘤检出率比较差异无统计学意义(X2=0.263,P=0.608). 结论 CTA对于直径不小于2 mm动脉瘤的早期诊断较准确.

Objective To assess the clinical value of CT angiography (CTA) in early diagnosis of intracranial aneurysms. Methods Forty-two patients with subarachnoid hemorrhage suspected to arise from intracranial aneurysms underwent 64-slice spiral CTA followed by digital subtraction angiography (DSA). Chi-square test was employed to analyze the differences between the results by CTA and DSA. Results CTA confirmed the diagnosis of intracranial anenrysms (2-26 in diameter) in 39 patients, with suspected aneurysm in 1 patient and negative result in another. DSA identified intracranial anenrysms in 41 patients and showed negative result in 1 patient. The aneurysm detection rate showed no significant difference between CTA and DSA (X<'2>=0.263,P=0.608). Conclusion CTA can accurately diagnose aneurysm with diameter no less than 2 mm.
