Summary

Surgery for acute type A aortic dissection (ATAAD) has high mortality. Arch replacement in ATAAD surgery increases stroke risk, suggesting individualized treatment based on patient condition.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Disease

Background:

  • Acute type A aortic dissection (ATAAD) necessitates surgical intervention, but the extent of repair remains debated.
  • Surgeons differ on conservative versus radical surgical approaches for ATAAD.
  • This study evaluates outcomes and prognostic impact of surgical strategy in ATAAD repair.

Purpose of the Study:

  • To assess surgical outcomes for ATAAD.
  • To determine the prognostic impact of aortic arch replacement in ATAAD surgery.
  • To compare outcomes between ascending/root replacement alone versus those including aortic arch replacement.

Main Methods:

  • Retrospective analysis of 601 patients undergoing ATAAD repair from 2005-2021.
  • Multivariable logistic and Cox regression used for risk factor and survival analysis.
  • Comparison of outcomes based on surgical strategy: with vs. without aortic arch replacement.

Main Results:

  • Operative mortality for ATAAD repair was 24.3%.
  • In-hospital mortality was comparable between ascending/root replacement (23.1%) and arch involvement (28.7%).
  • Arch replacement was associated with a higher rate of cerebrovascular complications (21.9% vs. 7.6%) despite younger patient demographics.

Conclusions:

  • ATAAD surgery continues to have high mortality.
  • Arch replacement in ATAAD patients is linked to increased stroke risk.
  • Individualized surgical strategy based on patient condition and dissection severity is recommended.
