Key result
Thoracic false lumen-perfused branches perpetuate false lumen flow, highlighting the need for novel devices.
Why the study?
Persistent thoracic false lumen flow and aortic expansion after thoracic endovascular aortic repair or aortic arch replacement are common, but robust imaging evidence of false lumen-perfused branches is lacking.
This review highlights the role of thoracic false lumen-perfused branches in perpetuating false lumen flow after aortic dissection repair, emphasizing the need for advanced imaging and novel therapeutic devices.
May guide branch-focused imaging in aortic dissection surveillance; leaves open device strategies for flow reduction.
Persistent thoracic false lumen flow and subsequent aortic expansion are common complications following thoracic endovascular aortic repair for type B aortic dissection, as well as aortic arch replacement with the elephant trunk technique for type A aortic dissection. Although thoracic false lumen-perfused branches are known to contribute to thoracic false lumen backflow, robust imaging evidence is still lacking. This review illustrates how these branches perpetuate thoracic false lumen flow through detailed imaging analysis, emphasizing the critical need for advancing rapid, accurate, and minimally invasive imaging techniques and novel therapeutic devices to address this persistent clinical challenge.

Ge et al. (2025) conducted a review in Aortic dissection (Type A and Type B) post-repair. Imaging analysis of thoracic false lumen-perfused branches was evaluated. Detailed imaging analysis illustrates that thoracic false lumen-perfused branches perpetuate false lumen flow, emphasizing the need for advanced imaging and novel therapeutic devices.
