Abstract: ［Abstract］ Objective Research and sum up of clinical application of MSCTA in diagnosis of cerebral aneurysms. Methods The clinical data of 60 patients with suspected subarachnoid hemorrhage who underwent MSCTA in our hospital from October 2014 to January 2017 were selected, Among them, 15 cases underwent conservative treatment, and the remaining 45 cases underwent MSCTA got surgical treatment, which including 41 cases underwent DSA endovascular treatment and 4 cases underwent craniotomy. The diagnostic accuracy, application value and the author’s experience of CTA were analyzed. Results A total of 47 cerebral aneurysms were diagnosed by MSCTA in 45 patients, while 49 cerebral aneurysms were detected by DSA and craniotomy. The diagnostic coincidence rate was 95.9%. There was no significant difference between CTA and DSA that used to analyze the long axis of the tumor, the short axis of the tumor, and the neck of the tumor, P>0.05. Conclusion For patients with intracranial aneurysms, the detection of MSCTA has important clinical significance. It is helpful, safe and reliable to show the tumor size and neck of the patients intracranial aneurysm.

摘要： ［摘要］目的 研究多层螺旋CT血管造影（MSCTA）诊断脑动脉瘤的临床应用。方法 选择我院2014年10月~2017年1月收治的60例蛛网膜下腔出血疑似脑动脉瘤患者进行的MSCTA检查的临床资料，其中15例行保守治疗；其余45例行MSCTA患者经过外科处理，包括41例经DSA血管内处理，4例经开颅手术治疗。分析CTA的诊断准确性、应用价值和作者的使用经验。结果 CTA：所有患者中45例MSCTA诊断脑动脉瘤共47个，DSA及开颅术发现脑动脉瘤49个，诊断符合率为95.9%；CTA与DSA对瘤体长轴、瘤体短轴与瘤颈进行分析显示，两种检测方法的检测数据均无明显差异，P>0.05。结论 对于颅内动脉瘤患者采取MSCTA检测的临床意义重要，有利于显示出患者颅内动脉瘤的瘤体大小与瘤颈，诊断方法安全、可靠。
