摘要

本文对一名50多岁的Budd-Chiari综合征患者在CT上诊断为肝上下腔静脉阻塞，在球囊血管成形术前后应用4D Flow MRI进行评估。在两个呼吸期获得的4D血流MRI，描绘了复杂的血流动力学和呼吸变异性，以及膜性下腔静脉狭窄通道处的急流。介入后4D血流MRI显示，经血流方向校正后，下腔静脉血流增加。

Assessing the Complicated Venous Hemodynamics and Therapeutic Outcomes of Budd-Chiari Syndrome with Respiratory-gated 4D Flow MR Imaging During the Expiratory and Inspiratory Phases.

A man in his 50s with Budd-Chiari syndrome diagnosed with the suprahepatic inferior vena cava (IVC) obstruction on CT was assessed using 4D Flow MRI before and after balloon angioplasty. 4D Flow MRI acquired in two respiratory phases, depicted complex hemodynamic and respiratory variability, and a jet stream at the narrowed channel of the membranous IVC. Post-interventional 4D Flow MRI showed that the IVC blood flow increased with corrected flow directions in the infrarenal IVC.
