目的评价16层螺旋CT对急性主动脉综合征的诊断价值.方法对34例急性主动脉综合征患者先行CT平扫,再进行追踪触发增强扫描和后处理,分析其CT表现.结果主动脉夹层23例,均可见真、假腔和内膜片,且可显示累及范围及并发症.壁内血肿6例,表现为主动脉周围环形或新月形低密度无强化影.穿透性溃疡5例,表现为突出于主动脉腔外的龛影.结论 16层螺旋CT能准确、全面的诊断急性主动脉综合征,为临床制定正确的治疗方案提供依据.

Objective To evaluate the value of 16-slice spiral computed tomography(SCT)in diagnosing acute aortic syndrome.Methods Thirty-four cases with acute aortic syndrome underwent 16-slice SCT,performed with unenhanced,contrast-enhanced scanning of bolus tracking and three-dimensional reconstruction.The CT findings of these cases were analysed.Results Twenty-three of them were confirmed Aortic Dessection(AD),the true and false lumen,intimal flap,extent involved and complications of which were all revealed.Six cases were confirmed intramural aortic hematoma(IMH),with features of ring or crescent-shaped non-enhanced thickening wall around the aorta.Five cases were confirmed penetrating atherosclerotic ulcer(PAU),with features of niche sign outstanding the lumen of the aorta.Conclusion Acute aortic syndrome can he diagnosed exactly and completely by 16-slice SCT,which can provide valuable information to select therapeutic methods.
