Summary

Surgical treatment for acute aortic dissection type A (AADA) involves replacement or reconstruction. Reconstruction offers lower mortality and reoperation rates, guiding procedure selection based on patient anatomy.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Diseases

Background:

  • Acute aortic dissection type A (AADA) presents complex surgical challenges.
  • Treatment options include aortic valve and ascending aorta replacement, reconstruction, or combined techniques.

Purpose of the Study:

  • To summarize surgical experiences with different AADA treatment methods.
  • To delineate indications for specific surgical procedures in AADA.

Main Methods:

  • Retrospective analysis of 51 patients undergoing surgery for AADA since 1979.
  • Comparison of outcomes for three surgical approaches: reconstruction, composite replacement, and combined techniques.

Main Results:

  • Overall AADA mortality was 25%.

  • Reconstruction showed the lowest mortality (12%), followed by composite replacement (18%), and combined techniques (47%).
  • Reconstruction group had a low reoperation rate (9%) with favorable long-term follow-up.
  • Conclusions:

    • Surgical approach for AADA should be tailored to intraoperative pathoanatomical findings.
    • Graft replacement is indicated for primary annuloectasia.
    • Reconstruction is preferred for patients with a normal ascending aorta and aortic annulus.
