摘　　要：为了探究64排螺旋CT脑血管造影在动脉瘤性蛛网膜下腔出血诊断中的应用价值,本文选取了152例动脉瘤患者,分析了64排螺旋CT脑血管造影对动脉瘤性蛛网膜下腔出血的诊断结果,评价了其诊断的灵敏度、特异性和准确性。结果显示,与数字减影血管造影检查结果相比,64排螺旋CT脑血管造影对动脉瘤性蛛网膜下腔出血患者的诊断灵敏度、特异性、准确率、阳性预测值和阴性预测值均无显著性差异(P>0.05);CT脑血管造影结果与手术中实际测量的动脉瘤各项数据也无显著性差异(P>0.05);而且对患者动脉瘤细节的显示优于数字减影血管造影,差异具有统计学意义(P<0.05)。本研究揭示了64排螺旋CT脑血管造影对于动脉瘤性蛛网膜下腔出血的诊断具有良好的效果,而且能够更好地展示患者的动脉瘤细节,对于指导制定脑动脉瘤手术方案有一定帮助,适合在临床推广使用。In order to explore the diagnostic effect of 64-slice spiral CT angiography in aneurysmal subarachnoid hemorrhage,152 cases of patients with aneurysms were performed with 64 row spiral CT cerebral angiography and digital subtraction angiography.We analyzed the results of 64 row spiral CT cerebral angiography on the diagnosis of aneurysmal subarachnoid hemorrhage,and evaluated its diagnostic sensitivity,specificity and accuracy.The clinical data showed that there was no significant difference between 64-slice spiral CT angiography and digital subtraction angiography in their diagnostic sensitivity,specificity,accuracy,positive predictive value and negative predictive value in patients with aneurysmal subarachnoid hemorrhage(P>0.05).In addition,the results of 64-slice spiral CT cerebral angiography showed no significant difference with the aneurysm data measured during surgery(P>0.05).Moreover,64-slice spiral CT angiography showed better aneurysm details than digital subtraction angiography(P<0.05).It was indicated that 64-slice spiral CT angiography has a good application value for the diagnosis of aneurysmal subarachnoid hemorrhage,and can better display the details of patients’aneurysms,which is helpful for guiding the development of surgical plans for brain aneurysms and suitable for clinical promotion.
