目的总结分析螺旋CT血管造影(CTA)技术在颅内动脉瘤诊断和术后评价中的应用价值。方法 95例颅内动脉瘤患者为研究对象,采用螺旋CTA检查,对照手术结果来评价螺旋CTA诊断动脉瘤的效果。结果 95例患者在螺旋CT平扫下可见蛛网膜下腔出血,最常见的为鞍上池出血,螺旋CTA共检测出108个动脉瘤,其中13例为2个瘤体。后交通动脉瘤52个(48.15%)、前交通动脉瘤32个(29.63%)、大脑中动脉瘤10个(9.26%)、颈内动脉颅内段动脉瘤8个(7.41%)、椎动脉瘤6个(5.56%);囊状动脉瘤75个(69.44%)、梭形动脉瘤21个(19.44%)、不规则动脉瘤12个(11.11%);瘤体直径2~21mm,平均瘤体直径(5.2±5.3)mm。95例患者中65例接受了夹闭术,螺旋CTA可清楚显示瘤夹数量及位置、动脉瘤闭塞情况、瘤颈残留情况、载瘤动脉与大血管通畅情况、载瘤动脉和动脉瘤夹间关系。可见瘤夹金属伪影。结论螺旋CTA技术能对颅内动脉瘤可进行准确诊断,为临床诊治提供可靠信息,也是颅内动脉瘤术后评价的重要方法 ,值得推广应用。 Objective To summarize and analyze the value of spiral CT angiography (CTA) in the diagnosis and postoperative evaluation of intracranial aneurysms. Methods Ninety-five patients with intracranial aneurysm were enrolled in this study. The results of spiral CT angiography (CTA) and spiral CT angiography (CTA) were used to evaluate the effectiveness of spiral CT angiography in the diagnosis of aneurysms. Results 95 patients showed subarachnoid hemorrhage under spiral CT scan, the most common was suprasellar hemorrhage. A total of 108 aneurysms were detected by helical CTA, of which 13 were two. 52 (48.15%) were posterior communicating aneurysms, 32 (29.63%) were anterior communicating aneurysms, 10 (9.26%) were cerebral aneurysms, 8 (7.41%) were intracarotid intracranial aneurysms, There were 6 tumors (5.56%), 75 (69.44%) saccular aneurysms, 21 (19.44%) saccular aneurysms, 12 aneurysms (11.11%), 2 ~ Body diameter (5.2 ± 5.3) mm. Of the 95 patients, 65 received clipping, and the CTA clearly demonstrated the number and location of aneurysm, the occlusion of the aneurysm, the remaining tumor neck, the presence of the parent artery and the great vessels, the gap between the parent artery and aneurysm relationship. Visible tumor clip metal artifacts. Conclusion Spiral CTA technique can accurately diagnose intracranial aneurysms and provide reliable information for clinical diagnosis and treatment. It is also an important method for postoperative evaluation of intracranial aneurysms and should be widely applied.
