摘　　要：目的探讨多层螺旋CT血管造影(MSCTA)对自发性蛛网膜下腔出血病因诊断的临床价值。方法经CT平扫诊断为自发性蛛网膜下腔出血39例,进行MSCTA检查及三维图像后处理,并均与DSA检查对照,适合介入治疗的病例,进行介入栓塞治疗。结果全部39例自发性蛛网膜下腔出血的病例共检查出动脉瘤23例,脑动静脉畸形1例,脑动脉硬化1例,未见异常14例。其中颈内动脉动脉瘤5例,前交通动脉动脉瘤7例,大脑中动脉动脉瘤5例,大脑前动脉动脉瘤1例,基底动脉动脉瘤1例,椎动脉动脉瘤1例,多发动脉瘤1例,23例患者中共检出24个动脉瘤,有1例为2个动脉瘤。脑血管病变的阳性率为64.3%。结论MSCTA检查是自发性蛛网膜下腔出血病因检查的一种简单、快速、无创及有效的方法。Objective To evaluate multi-slice spiral computed tom og raphy angiography (MSCTA) on the etiological diagnosis of spontaneous subarachno id hemorrhage (SAH). Methods Thirty-nine patients, who were initially diagnose d as SAH, underwent MSCTA and digital subtraction angiography (DSA). The MSCTA w as compared with DSA on the etiological diagnosis. Intervention was performed on proper patients. Results The lesions found by MSCTA included cerebral aneurysms ( n=23) , vascular malformation ( n=1) , arteriosclerosis( n=1) . The 23 aneurysms were located at: anterior communicating artery (n=7), internal carotid artery (n=8), middle cerebral artery (n=5), anterior cerebral artery (n=1), bas ilar artery (n=1), vertebral artery (n=1), multiple arteries (n=1). Conclusion M SCTA was a simple, quick, noninvasive and effective modality to determine the fu ndamental lesions of spontaneous subarachnoid hemorrhage.
