【摘要】 目的:探讨多层螺旋CT三维血管成像(3DMSCTA)作为自发性蛛网膜下腔出血首选病因诊断方法的临床价值。方法:回顾搜集了2002年1月至2005年3月自发性蛛网膜下腔出血患者71例,均行数字减影血管造影(DSA)检查和多层螺旋CT血管造影检查,比较二种影像学方法的优缺点。结果:71例中,DSA发现动脉瘤58例,其中发生在颈内动脉床突上段3例,前交通支20例,大脑前动脉2例,后交通支23例,基底动脉5例,大脑中动脉主干侧裂分叉部3例,多发小动脉瘤2例;动静脉畸形6例;动静脉畸形合并动脉瘤3例;静脉性血管异常2例;阴性2例。3DMSCTA检出大小动脉瘤61个,显示瘤体、瘤颈、载瘤动脉和与周围血管及颅骨的关系清晰、确切。显示畸形血管团的部位大小,供血动脉来源,引流静脉的分支情况,空间立体结构清晰。71例DSA检查者,CTA诊断符合者67例;2例MSCTA发现动脉瘤,DSA检查阴性;MSCTA漏诊2例;2例经CT平扫显示有蛛网膜下腔出血,而MSCTA与DSA均无阳性发现。所有患者中29例行血管内栓塞治疗,手术治疗35例,内科保守治疗7例。结论:3DMSCTA检查诊断蛛网膜下腔出血性疾病的敏感性高,是一种安全、无创、简便、快速、准确的诊断方法。更多还原

【Abstract】 Objective:To compare the accuracy of 3D MSCTA and DSA in the etiological diagnosis of spontaneous subarachnoid hemorrhage (SAH). Methods:Performance of 3D MSCTA and DSA in the etiological diagnosis of 71 cases of spontaneous SAH were reviewed retrospectively and compared.Results:With DSA,58 patients were found had aneurysm,6 had AVM,3 had AVM with aneurysm,2 had malformation of veins and 2 were negative.Etiological diagnoses of MSCTA were consistent with that of DSA in 67 patients.As for the remaining 4 patients,2 aneurysms detected by 3D MSCTA were missed with DSA while 2 aneurysms found with DSA were missed with 3D MSCTA.Conclusion:3D MSCTA has a similar accuracy in the etiological diagnosis of spontaneous SAH to DSA.更多还原
