目的探讨64层螺旋CT血管造影(computed tomography angiography,CTA)对颅内动脉瘤的诊断价值,以及对动脉瘤夹闭术后评价的价值。方法回顾性分析25例临床拟诊为颅内动脉瘤的临床资料,患者均进行了64层CTA检查,其中21例行手术治疗,术后再行CTA复查,比较两次CTA结果,评价动脉瘤夹闭情况。结果在25例患者中64层螺旋CTA共发现21例25个动脉瘤,CTA可清楚显示动脉瘤位置、大小、形态及与周围结构的关系,与手术所见一致(符合率100%)。动脉瘤夹闭术后CTA能够清楚显示动脉瘤体消失,显示载瘤动脉与动脉瘤夹之间关系及动脉瘤夹的数量和位置。结论64层螺旋CTA在诊断颅内动脉瘤及动脉瘤术后随访中具有重要临床价值。
Objective To investigate the diagnostic value of 64-slice computed tomography angiography (CTA) for intracranial aneurysms and evaluate the value of postoperative evaluation of aneurysm clipping. Methods The clinical data of 25 cases diagnosed as intracranial aneurysms were analyzed retrospectively. All the patients underwent 64-slice CTA. Among them, 21 cases underwent surgical treatment and CTA after operation. The results of two CTAs were compared and evaluated for aneurysm Closure situation. Results Twenty-five aneurysms of 21 cases were found in 64 patients with CTA. The location, size and shape of the aneurysm and the relationship with the surrounding structures were clearly shown by CTA. The findings were consistent with the surgical findings (with a coincidence rate of 100%). Aneurysm CTA can clearly show the disappearance of aneurysm, showing the relationship between the parent artery and aneurysm clips and the number and location of aneurysm clips. Conclusion 64-slice CTA has important clinical value in the diagnosis of intracranial aneurysms and follow-up of aneurysms.
