摘要
目的评价16层螺旋CT血管成像(CTA)在颅内动脉瘤急诊外科夹闭治疗中的临床应用价值。方法43例颅内动脉瘤的患者纳入本研究,全部行16层螺旋CTA检查。运用最大密度投影和容积再现技术评价动脉瘤的形态、大小、位置和瘤颈形态及动脉瘤与颅骨和周围血管的关系,并根据16层螺旋CTA结果行急诊外科治疗。结果16层螺旋CT三维重建图像能够准确地提供颅内动脉瘤的部位、瘤体、瘤颈大小和动脉瘤与载瘤动脉的关系,并且,能够帮助神经外科医师顺利找到动脉瘤后成功夹闭。结论16层螺旋CTA是一种准确微创的诊断颅内动脉瘤的方法,并能够提供足够的信息指导动脉瘤的急诊外科治疗。
Objective To assess the clinical value of 16-slice CT angiography in emergent surgical clipping ofintracranial aneurysms. Methods 3 patients with intracranial aneurysms were included in the study and successively underwent 16-slice CTA examination. Using maximum-intensity projections and volume-rendering techniques, neuroradiologist performed the morphology, size and location of the aneurysms, neck geometry, and the relationship of aneurysms to bone structures and adjacent branch vessels. Emergent surgical procedure based on 16-slice CTA images. Results The 16- slice three-dimensional images clearly provided the location of aneurysms, the size of the sac and the neck, and the relationships between aneurysms and parent arteries, and the information would help the neurosurgeons fred the aneurysms and clip them successfully. Conclusion Sixteen-slice CTA is an accurate and noninvasive imaging examination for the diagnosis of intracranial aneurysms, and it can provide sufficient diagnostic information in guiding the emergent surgical clipping of aneurysms.
