Aortic arch surgery, including hypothermia and circulatory arrest, shows acceptable risk. Experience and strategy improved outcomes, reducing mortality from 13.9% to 8.0% since 1987.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • Aortic arch interventions are complex procedures.
  • Aneurysms and dissections pose significant risks.

Purpose of the Study:

  • To evaluate the outcomes of aortic arch interventions.
  • To assess the impact of hypothermia and circulatory arrest on patient mortality.

Main Methods:

  • 133 aortic arch interventions performed between 1980 and 1991.
  • Procedures utilized hypothermia and circulatory arrest.
  • Aortic valve replacement was frequently combined with arch repair.

Main Results:

  • Early mortality was 13.9%, with higher rates in acute aortic dissection (20.5%).

  • Neurological and cardiac events were leading causes of early death.
  • Overall mortality decreased to 8.0% after 1987.

    • Conclusions:

    • Aortic arch operations can be performed with acceptable risk.
    • Growing experience, proper indication, and operative strategy are crucial.
    • Hypothermia and circulatory arrest are valuable tools in aortic arch surgery.
