Why the study?
Patients with type B aortic dissection lacking optimal landing zones still pose significant challenges for thoracic endovascular aortic repair.
Does surgical stent-graft implantation combined with supra-aortic vessels transposition improve outcomes in patients with type B aortic dissection lacking optimal landing zones?

Surgical stent-graft implantation with supra-aortic vessel transposition via median sternotomy is a viable alternative for type B aortic dissection patients lacking optimal landing zones for TEVAR.

May offer an alternative for type B aortic dissection without optimal landing zones; hypothesis-generating and should not yet change practice.
Thoracic endovascular aortic repair (TEVAR) has been considered as a first-choice treatment for type B aortic dissection (TBAD). However, some patients that is lack of optimal landing zones (<15 mm in dissected Z₂, Z₃ or the presence of a lusorian artery) still pose significant challenges for TEVAR. We utilized a surgical stent-graft implantation in the descending aorta combined with supra-aortic vessels transposition through median sternotomy for these special TBAD patients. The short- and mid-term results showed that our procedure is a good and alternative therapy for such kind patients.
