摘要

目的:探讨64层螺旋CT血管造影（CTA）在蛛网膜下腔出血（SAH）病因诊断中的作用。方法:对2005年9月到2006年9月收治入院的89例SAH患者行64层螺旋CT血管造影检查

其中49例同时接受数字减影血管造影（DSA）检查。分析CTA检查结果并与DSA检查结果比较。结果:89例患者中CTA检出动脉瘤70例

动静脉畸形9例

静脉窦血栓2例

阴性8例;在同时接受DSA检查的49例患者中

发现动脉瘤41例

动静脉畸形4例

阴性4例

其中除1例CTA发现并经临床证实的动脉瘤DSA检查为阴性外

其余全部证实CTA诊断。CTA对SAH病因诊断中的敏感性和特异性都为100%

DSA分别为98%和100%。结论:64层螺旋CTA对SAH的病因诊断是一种无创、快速、便捷的影像学检查方法

可显示血管的空间立体结构及周边关系

有助于治疗方法的选择和难度的评估。

Abstract

Objective:To evaluate of value of 64-slices spiral CT angiography(CTA)in the etiological diagnsis of subarachnoid haemorrhage(SAH).Methods:CTA was performed in 89 cases with spontaneous SAH admitted from September 2005 to September 2006

49 of whom also underwent digital subtracted angiography(DSA).The findings of CTA were compared with the results of DSA.Results:Among the 89 patients

CTA revealed 69 cases with cerebral aneurysm

9 arteriovenous malforma- tion(AVM)

2 thrombus of venous sinues

8 negative findings.Among the 49 patients who underwent both CTA and DSA

all but 1 lesions showed by CTA

either cerebral aneurysms(n=41)or AVMs(n=4)

were confirmed by DSA.DSA failed to show one case of small anterior communicating aneurysm demonstrated by CTA.It was found that CTA sensitivity and specificity was 100% and that DSA sensitivity was 98% and specificity was 100% in diagnosis of intracranial aneurysms in etiological diagnosis of SAH.Conclusion:64-slices spiral CTA is a non-invaise

fast convenience imaging modality for etiological diag- nosis of the SAH and also play an important role in selecting therapy and assessing difficulties of treatment.
