摘　　要：目的分析烟雾病的CT平扫及CT血管成像(CTA)特征,旨在提高对烟雾病的认识。方法12例烟雾病患者均行CT平扫和CTA检查,在ADW4.4(或4.5)工作站上做最大密度投影(MIP)、多面重建(MRP)、容积重现(VR)。结果本组12例,平均年龄(43±25)岁,缺血型4例、其中2例表现为多发脑梗死,1例表现为腔梗、1例表现为软化灶,出血型8例,脑实质出血4例、脑室出血2例,脑实质出血并蛛网膜下腔出血1例、蛛网膜下腔出血1例。CTA均能清晰显示发生狭窄、闭塞的颈内动脉,Willis环血管远段明显增多、扩张的脑底部侧支血管,一侧颈内动脉C3~5段明显狭窄1例,一侧大脑前动脉A1及M1段狭窄4例,双侧大脑前A1段,双侧中动脉M1段及双侧大脑后动脉P1段狭窄闭塞4例,双侧大脑前动脉A1段及双侧大脑中动脉M1段狭窄闭塞3例,12例患者有10例见到颅底异常血管网。结论MSCT平扫及CTA对烟雾病的诊断具有重要价值。Objective To analyze the CT scan and CTA characteristics of moyamoya disease,aiming to improve the understanding of moyamoya disease.Methods Twelve patients with moyamoya disease underwent CT plain scan and CTA examination.Maximum density projection(MIP),multifaceted reconstruction(MRP),and volume(VR)were performed on the ADW4.4(or 4.5)workstation.Results There were 12 patients with an average age of(43±25)years old,4 patients with ischemic type,2 patients with multiple cerebral infarction,1 patient with luminal infarction,1 with softening lesion,8 with hemorrhage,and 4 with hemorrhage.For example,2 cases with intraventricular hemorrhage,1 case with parenchymal hemorrhage and subarachnoid hemorrhage,and 1 case with subarachnoid hemorrhage.CTA can clearly show the stenosis,occlusion of the internal carotid artery,the distal segment of the willis ring,and the collateral vessels in the bottom of the brain,which increased and dilated-The internal carotid artery on one side of the C3~5 segment was significantly narrowed in one case,the anterior cerebral artery on one side was A1 and M1 stenosis in four cases,the bilateral anterior cerebral A1 segment,the bilateral middle artery M1 segment,and the bilateral posterior cerebral artery P1 segment were occluded.In 4 cases,stenosis and occlusion of bilateral anteri-or cerebral artery A1 segment and bilateral middle cerebral artery M1 segment occurred in 3 cases,and abnormal vascular network of the skull base was seen in 10 of 12 patients,collateral vessels and their branches were thick,tor-tuous,and increased.Conclusion MSCT plain scan and CTA have important value in the diagnosis of moyamoya disease.
