Summary
The Y-graft technique simplifies aortic arch replacement, a complex surgery. This method shows favorable early outcomes with low stroke risk, improving patient survival rates.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Aortic arch replacement is a high-risk cardiovascular operation.
- The Y-graft technique simplifies arch reconstruction and reduces cerebral ischemia.
- Early outcomes of Y-graft variations were examined.
Purpose of the Study:
- To evaluate the early outcomes of aortic arch replacement using the Y-graft technique.
- To assess the safety and efficacy of single and double Y-graft variations.
- To compare the Y-graft technique with traditional methods.
Main Methods:
- Aortic arch replacement was performed in 55 patients using the Y-graft technique.
- Axillary cannulation and hypothermic circulatory arrest with antegrade cerebral perfusion were utilized.
- A first-stage elephant trunk repair was performed in 84% of patients.
Main Results:
- No in-hospital deaths and a 2% 30-day mortality rate were observed.
- The stroke rate was 5%, with only one transient event.
- Actuarial 2-year survival was 77.6% ± 5.7%.
Conclusions:
- The Y-graft technique offers favorable early results for aortic arch replacement.
- It facilitates effective antegrade cerebral perfusion during complex procedures.
- The technique is associated with a low risk of neurologic complications.
