| 摘 要： | 目的探讨CT血管造影(CTA)对于急性期动脉瘤性蛛网膜下腔出血(SAH)的病因学诊断价值。资料与方法回顾性分析经CT平扫及腰穿明确诊断的自发性SAH38例患者资料,在SAH急性期(3～10天)做CTA并与数字减影血管造影(DSA)全脑动脉造影检查比较。结果38例患者中MSCTA发现动脉瘤32例,显示瘤体、瘤颈、载瘤动脉和与周围血管及颅骨的关系清晰、确切。对动脉瘤的检出敏感性为96.97%,特异性为100%。结论MSCTA是简单、快速、无创、安全、可靠的脑血管成像技术,在一定程度上可替代DSA检查,可作为SAH急性期患者病因诊断的首选筛查方法。

| Abstract: | Objective To analyse the value of CTA in the etiological diagnosis of acute SAH caused by aneurysm.Materials and Methods Thirthy-eight spontaneous SAH patients proved by CT plain scan and lumbar puncture were collected in our study,.CTA was performed at the acute stage (3-10 days after SAH ) and the data was compared with DSA.Results MSCT detected 33 aneurysm in 38 patients.Aneurysm body,aneurysm neck,parent artery and the relationship with surrounding vessels and bone structures were revealed distinctly an... |
