多通道主动脉夹层（MCAD）的血流动力学功能需要密切监测和有效管理，以避免潜在的灾难性后遗症。本报告描述了一位47岁的男性，根据MCAD的四维（4D）流磁共振成像结果接受血管内修复。获得的4D血流数据显示假腔内复杂的双向血流模式，压缩后的真腔内血流加速。塌陷的腹部真腔在初次撕裂修复后扩张不理想，需要进一步用裸支架重建。本病例研究表明，利用四维血流磁共振成像进行血流动力学分析有助于了解MCAD复杂的病理变化。
The hemodynamic function of multichanneled aortic dissection (MCAD) requires close monitoring and effective management to avoid potentially catastrophic sequelae. This report describes a 47-year-old man who underwent endovascular repair based on findings from four-dimensional (4D) flow magnetic resonance imaging of an MCAD. The acquired 4D flow data revealed complex, bidirectional flow patterns in the false lumens and accelerated blood flow in the compressed true lumen. The collapsed abdominal true lumen expanded unsatisfactorily after primary tear repair, which required further remodeling with bare stents. This case study demonstrates that hemodynamic analysis using 4D flow magnetic resonance imaging can help understand the complex pathologic changes of MCAD.
