摘要

目的:探讨三维CT血管造影（Three dimensional-computed tomography angiography

3D-CTA）在颅内动脉瘤病因诊断和治疗中的临床价值。方法:对2007年9月至2008年8月就诊的115例自发性蛛网膜下腔出血患者先进行头部3D-CTA检查

后进行DSA检查

检出动脉瘤89例

动脉瘤瘤颈夹闭术（81例）和介入栓塞术（8例）

行手术和血管介入患者1周后全部行CTA复查

比较术前3D-CTA与DSA结果。结果:89例患者CTA检出颅内动脉瘤97个

DSA检出颅内动脉瘤93个。其中5例CTA发现并经手术证实的前交通动脉小动脉瘤和3例后交通动脉小动脉瘤DSA检查为阴性;4例CTA检查阴性

DSA检查发现颅内动脉瘤并经手术证实

3D-CTA对颅内动脉瘤病因诊断的敏感性为95.6%

特异性为100%

准确性为96%

与DSA或/和手术诊断符合率为88.1%。结论:3D-CTA诊断结果与2D-DSA或/和手术诊断符合率较高

应灵活地结合CTA和DSA检查对颅内动脉瘤达到最大程度上的正确诊断。

Abstract

Objective:To explore of clinical value of three-dimensional computed tomography angiography(3D-CTA) in the etiological diagnosis and management of intracranial aneurysm.Methods:One hundred and fifteen patients with spontaneous SAH admitted from September 2007 to August 2008 were examined with 3D-CTA

and were examined with digital subtracted angiography(DSA)

and eighty nine patients were found suffering from intracranial aneurysm which underwent DSA.Repeated 3D-CTA was performed 1 week after clipping in eighty one patients or embolization in eignt cases.The findings of 3D-CTA were compared with the results of DSA.Results:A total of ninty seven aneurysms in eighty nine cases were detected by 3D-CTA

but DSA revealed ninty three anurysms.DSA confirmed the findings of CTA except for five cases of small anterior communicating aneurysms and three cases posterior communicating aneurysms which were demonstrated by 3D-CTA and verified by surgery but missed by DSA and four cases which were found by DSA and verified by surgery but missed by 3D-CTA.The sensitivity of 3D-CTA to diagnose the intracranial aneurysms is 95.6% and the specificity is 100% and the accuracy is 96%.The diagnose accordance rate among 3D-CTA and DSA and/or surgery is 88.1%.Conclusion:3D-CTA and 2D-DSA and/or surgery have high diagnose accordance rate

and we should combine the two diagnostic techniques to examine intracranial aneurysms accurately.
