摘要 目的:探讨主动脉壁内血肿的64层螺旋CT血管成像(MSCTA)的诊断价值及影像特征。方法:临床怀疑主动脉夹层行多排螺旋CT扫描确诊为主动脉壁内血肿9例,采用多平面重建(MPR),曲面重建(CPR),最大密度投影(MIP)等方法显示壁内血肿及血管壁溃疡并按Stanford分型。结果:9例主动脉壁内血肿,3例为A型,6例为B型。CT主要表现为:①主动脉壁呈环壁增厚或偏侧性新月形增厚,增厚血肿壁≥5mm(9例);②主动脉内壁溃疡形成(4例);③内膜瓣钙化、内移征(3例);④并发胸腔积液、心包积液(7例)。结论:CTA薄层轴位结合MPR、CPR及MIP均可清楚显示血肿的部位、累及范围、血肿程度以及并发症,64-MSCTA检查可对主动脉壁内血肿进行明确诊断及鉴别诊断。
