64层螺旋CT血管成像在脑动脉瘤术前评价中的临床应用

目的：探讨64层螺旋CT血管成像在脑动脉瘤术前评价中的临床应用价值。方法：对52例患者行64层螺旋CT血管成像检查。运用容积再现、最大密度投影及多平面重组评价动脉瘤的大小、形态和位置。结果：52例患者共发现动脉瘤59个,其中6例患者为多发;后交通动脉瘤31个,前交通动脉瘤16个,基底动脉瘤9个,前动脉动脉瘤3个。59个动脉瘤呈囊状41个,梭形5个,不规则形13个。动脉瘤平均直径为7.2 mm,瘤体大小平均为6.5 mm,瘤颈平均宽度为4.1 mm。29例患者伴有蛛网膜下腔出血。结论：64层螺旋CT血管成像能能准确提供关于脑动脉瘤的信息,指导外科手术夹闭及栓塞治疗,降低治疗风险,提高治疗成功率。

Clinical Application of 64-Slice Spiral CT Angiography in Preoperative Evaluation of Cerebral Aneurysms

Objective To explore the clinical application value of 64-slice spiral CT angiography in the preoperative evaluation of cerebral aneurysms.Methods 52 cases of patients were examined by 64-slice spiral CT angiography.Volume rendering,maximum intensity projection,multiplanar reformation were used to evaluate the size,shape and position of the cerebral aneurysms.Results Among the 52 patients,there were 59 aneurysms with cases of 6 patients being multiple,31 posterior communicating artery aneurysm,16 anterior communicating artery aneurysm,9 basilar artery aneurysm and 3 artery aneurysm.Among the 59 aneurysms,there were 41 cystic,5 spindle and 13 irregular-shape.The average diameter of aneurysm was 7.2mm,the average size was 6.5mm and the average width of aneurysmal neck was 4.1mm.In addition,there were 29 cases accompanied by subarachnoid blood.Conclusion 64-Slice Spiral CT Angiography can provide accurate information on cerebral aneurysms and guidance on surgical clipping and endovascular embolization to reduce the risk of treatment and improve the success rate of treatment.
