We review the angiographic and CT findings, precipitating factors and clinical features in nine patients with ten intracranial arterial dissections. The internal carotid artery was involved in five cases, the vertebral artery in four and the posterior inferior cerebellar artery in one. Angiography revealed irregular stenosis in four cases, irregular stenosis and a pseudoaneurysm in two, irregular stenosis and irregular dilatation in one, arterial occlusion in two and a pseudoaneurysm in one. CT demonstrated an infarct in four cases, a dense middle cerebral artery in two and subarachnoid haemorrhage in one. A possible precipitating factor was identified in five cases. Six patients recovered well, while three had persisting neurological deficits.
我们回顾了9例患者10处颅内动脉夹层的血管造影和CT表现、促发因素及临床特征。其中5例累及颈内动脉，4例累及椎动脉，1例累及小脑后下动脉。血管造影显示，4例为不规则狭窄，2例为不规则狭窄合并假性动脉瘤，1例为不规则狭窄合并不规则扩张，2例为动脉闭塞，1例为假性动脉瘤。CT显示，4例有梗死灶，2例大脑中动脉高密度影，1例蛛网膜下腔出血。5例确定了可能的促发因素。6例患者恢复良好，3例有持续性神经功能缺损。
