摘　　要：目的探讨CT血管造影(CTA)在脑动脉瘤诊断中的应用价值。方法对26例自发性蛛网膜下腔出血(SAH)患者行CTA,寻找动脉瘤(包括动脉瘤的部位、大小、数目),并经数字减影血管造影(DSA)或手术证实。结果本组26例患者共检出21例22个动脉瘤(1例为2个动脉瘤),其中前交通动脉瘤8个,后交通动脉瘤2个,大脑前动脉瘤4个,大脑中动脉瘤5个,颈内动脉瘤3个,10例患者经DSA证实,15例患者经手术证实,1例患者因病情发展迅速,行DSA及手术前死亡。结论CTA无创伤、费用低、安全可靠、所需时间短、三维立体成像空间分辨率高,对于SAH患者的破裂动脉瘤检出有较高的准确性,可以作为SAH患者筛查动脉瘤的初选方法。Objective To evaluate the clinical diagnostic values of computed tomographic angiography （CTA） for cerebral aneurysns. Methods 26 patients with SAH were examined by CTA and looked for cerebral aneurysns, then confirmed by digital subtraction angiography （DSA） or CT. Results Among the 26 patients there were 21 patients with 22 cerebral aneurysns （1 patient with two cerebral aneurysns）,8 anterior communication aneurysns, 2 posterior communication aneurysns, 4 anterior cerebral artery aneurysns, 5 middle cerebral artery aneurysns, 3 internal carotid artery aneurysns. 10 patients performed by DSA and 15 patients confirmed by operation. 1 patient died defore confirmed by DSA or operation because his condition was extremely danger. Conclusion CTA has the following characteristic： without trauma, low price, relative safe, the time consuming short, triaxiality stereo image and spatial resolution was excellent; the sensitive of diagnosis aneurysns in SAH was better. CTA can be served as the first choice for SAH to look for aneurysns.
