Objective:

To evaluate the safety and effectiveness of a non-customized modular aortic arch stent-graft.

Key Findings:
  • Technical success rate was 100%.
  • 30-day mortality rate was 3%, and stroke rate was 9%.
  • Overall survival rates were 91% at 12 months, 86% at 24 months, and 81% at 36 months.
  • 10 patients developed endoleaks, none requiring reintervention.
Interpretation:

Modular branched stent-graft repair for aortic arch disease is feasible with safety rates comparable to custom-made devices, hybrid techniques, and open surgery.

Limitations:
  • Limited sample size of 88 patients.
  • Short follow-up duration for long-term outcomes.
Conclusion:

Long-term comparative effectiveness studies are needed to determine if the modular stent-graft is superior to other interventions.
