Distal reentry as a functional primary entry: Insights from blood flow simulation in residual DeBakey IIIb aortic dissection after thoracic endovascular aortic repair

Thoracic endovascular aortic repair (TEVAR) is a common intervention for dissecting thoracoabdominal aortic aneurysms; however, long-term aortic dilation remains a concern. We report a case of residual type B aortic dissection treated with 2 TEVARs, where computational fluid dynamics (CFD) highlighted the hemodynamic role of distal reentries.
