Summary

Total aortic arch replacement is an acceptable procedure for distal aortic arch aneurysms. This technique, utilizing antegrade ascending aortic perfusion, effectively avoids thromboembolic complications.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Thoracic Surgery

Context:

  • Distal aortic arch aneurysms pose significant surgical challenges.
  • Traditional surgical approaches carry risks of complications.
  • Advancements in surgical techniques are crucial for improving outcomes.

Purpose:

  • To evaluate the efficacy and safety of total aortic arch replacement for distal aortic arch aneurysms.
  • To assess the utility of antegrade ascending aortic perfusion in this procedure.
  • To report outcomes including mortality and cerebral complications.

Summary:

  • 13 patients underwent total aortic arch replacement using a four-limbed artificial graft.
  • The procedure involved median sternotomy, cardiopulmonary bypass, selective cerebral perfusion, and open distal anastomosis.

  • Mortality was 16% (2 patients), primarily in those with ruptured aneurysms and preoperative shock. No severe cerebral complications occurred.
  • Impact:

    • Total aortic arch replacement is a viable and acceptable surgical option for distal aortic arch aneurysms.
    • Antegrade ascending aortic perfusion is a beneficial method to prevent thromboembolic events associated with retrograde perfusion.
    • The study highlights the importance of surgical technique in managing complex aortic pathologies.
