摘要
目的探讨64层螺旋CT血管成像(CTA)在自发性蛛网膜下腔出血患者病因诊断中的临床价值。资料与方法回顾性分析118例急性原发性蛛网膜下腔出血患者的资料,分别进行64层螺旋CT检查及数字减影血管造影,并进行容积再现、最大密度投影、曲面重组、多平面重组等后处理。结果 CTA发现动脉瘤合并动静脉血管畸形3例,动静脉畸形19例,动脉瘤88例(单个瘤体83例,2个瘤体5例),CTA阴性8例。动脉瘤直径1.5～32mm;CTA能够清楚地显示动脉瘤瘤体的大小、瘤颈、瘤轴指向、载瘤动脉与血管的关系及三维空间关系等。结论 CTA诊断动脉瘤所致自发性蛛网膜下腔出血病因的准确率较高,能够指导临床诊断及治疗。
Purpose To evaluate 64-slice CT angiography （CTA） in the etiological diagnosis of spontaneous subarachnoid hemorrhage （SAH）. Materials and Methods 118 patients with acute SAH underwent 64-slice CTA and digital subtraction angiography （DSA）. Three-dimensional post-processing techniques including volume rendering （VR）, maximum intensity projection （MIP）, curved planar reformation （CPR） and multi-planar reconstruction （MPR） were underwent. Results CTA indicated 3 patients had aneurysm and arteriovenous malformation, 19 patients had arteriovenous malli^rmations, 88 patients had aneurysm （including 83 cases of single tumor and 5 cases of double ttnnors）, 8 patients showed negative CTA results. The diameter of arterial aneurysm was 1.5-32 ram. CTA could clearly display the size, the neck and axis direction of the detected aneurysms, and their three-dimensional spatial relationship with parental arteries. Conclusion CTA can accurately diagnose the etiology of SAH, and can guide the diagnosis and therapy in clinic.
