Summary
Open stented elephant trunk (SET) repair for complicated Stanford type B aortic dissection (TBAD) shows promising results. This technique offers a viable alternative treatment option with good long-term outcomes and no mortality in a small patient cohort.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Complicated Stanford type B aortic dissection (TBAD) poses significant therapeutic challenges.
- Open stented elephant trunk (SET) repair, with or without brachiocephalic artery bypass, is an emerging treatment modality for TBAD.
Purpose of the Study:
- To evaluate the clinical outcomes and feasibility of open stented elephant trunk (SET) repair in patients with complicated Stanford type B aortic dissection (TBAD).
Main Methods:
- Ten consecutive patients with complicated TBAD underwent open SET repair between May 2016 and November 2018.
- Clinical data and long-term outcomes were collected via electronic medical records and patient interviews.
Main Results:
- No postoperative mortality was observed in the ten patients (9 males, 1 female; average age 47.3 years).
- Patients experienced manageable postoperative complications, with full recovery at discharge.
- Long-term computed tomography angiography revealed complete aortic remodeling and normal blood supply without anastomotic complications.
Conclusions:
- Open stented elephant trunk (SET) repair is a safe and effective treatment for complicated Stanford type B aortic dissection (TBAD).
- The procedure demonstrates satisfactory clinical outcomes and can be considered an alternative surgical option.
- Further large-scale studies with extended follow-up are warranted to solidify these findings.
