Summary

Organ malperfusion in acute aortic dissection significantly increases mortality. An antecedent operation strategy for malperfusion cases demonstrated improved outcomes compared to non-operative management.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Thoracic Surgery

Background:

  • Organ malperfusion is a critical complication of acute aortic dissection.
  • Treatment strategies for acute aortic dissection with organ malperfusion remain controversial.
  • This study investigates the management strategy and outcomes for patients with acute aortic dissection and organ malperfusion.

Purpose of the Study:

  • To evaluate the effectiveness of an antecedent operation strategy in managing acute aortic dissection with organ malperfusion.
  • To compare outcomes between patients with and without organ malperfusion.
  • To identify factors influencing the outcome of acute aortic dissection with organ malperfusion.

Main Methods:

  • Retrospective analysis of 134 acute aortic dissection patients admitted between January 1995 and December 1998.

  • 24 patients (17.9%) presented with organ malperfusion affecting various organs.
  • Management strategy involved prioritizing antecedent operation for malperfusion.

    • Main Results:

    • Overall mortality in patients with malperfusion was 33.3%, with operative mortality at 31.3% for those undergoing antecedent operation.
    • In contrast, overall mortality for patients without malperfusion was 11.8%.
    • The antecedent operation strategy was deemed mandatory for selected malperfusion cases.

    Conclusions:

    • Organ malperfusion is a significant determinant of outcome in acute aortic dissection.
    • An appropriate management strategy, including antecedent operation, is crucial for improving patient outcomes.
    • Timely and effective therapeutic interventions are essential for managing acute aortic dissection with organ malperfusion.
