摘要:
目的探索血流动力学因素在DeBakeyⅢ型主动脉夹层发生、发展以及临床预后评估中的作用。方法通过CT扫描获取临床常见典型形态的DeBakeyⅢ型主动脉夹层断层图像序列，重建出三维主动脉夹层血流动力学分析计算机模拟模型，采用计算流体力学数值模拟方法对主动脉夹层真假腔内的血液流场进行数值模拟分析。结果①单破口型夹层假腔压强持续高于真腔压强，呈现“吹气球”效应；②当DeBakeyⅢ型主动脉夹层真腔受压狭窄时，真腔内压强将低于假腔内压强，夹层真腔内血流流线也会出现部分中断；③夹层撕破口附近的动脉管壁局部血流动力学因素可出现失衡现象。结论DeBakeyⅢ型主动脉夹层真假腔压强失衡可导致假腔持续扩张、压迫真腔。夹层管壁局部血流动力学改变可能是慢性期B型夹层破裂的危险因素。
