Tóm tắt

Objectives: We report two clinical cases that wherein stent graft-induced new entry (dSINE) after frozen elephant trunk (FET) procedure for type A aortic dissection were resolved successfully by additional stent graft placement.


Methods: Describe rare clinical cases.


Results: Two patients were hospitalized after FET procedure for type A aortic dissection treatment. The former had refractory abdominal pain and the latter had sudden chest pain; both their abdominal thoracic CT scanner showed dSINE. We decided to place additional stent grafts to cover the new entry. Both patients recovered well and were discharged after 5 and 12 days, respectively, without any significant complications.


Conclusions: Supplemental stent graft placement is an effective and safe treatment choice for dSINE post-FET procedure.
