Age, ruptured aortic aneurysms, and renal dysfunction significantly increase mortality and disability risks in aortic arch operations with selective cerebral perfusion. These factors are key predictors for patient outcomes.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Aneurysm Repair
  • Cerebral Perfusion Techniques

Background:

  • The risks associated with aortic arch operations using selective cerebral perfusion for nondissecting aneurysms remain unclear.
  • A need exists to determine factors influencing mortality and disability in these complex procedures.

Purpose of the Study:

  • To evaluate the predictors of mortality and disability in patients undergoing aortic arch surgery with selective cerebral perfusion.
  • To identify patient characteristics and conditions that impact outcomes after thoracic aneurysm repair.

Main Methods:

  • A multicenter, retrospective study involving 143 patients undergoing aortic arch or extensive aortic reconstruction.
  • Procedures included graft replacement, extensive aortic reconstruction, and patch repair.

  • A mean follow-up of 19 months was conducted.

    • Main Results:

    • Hospital mortality was 25.2% (36/143 patients).
    • Independent predictors for vascular death included aneurysmal rupture and renal dysfunction.
    • Neurologic deficits occurred in 10.5% of patients, with reoperation needed for 13 patients.

    Conclusions:

    • Age, aneurysmal rupture, and renal dysfunction are significant predictors of mortality and disability.
    • These findings are crucial for risk stratification in aortic arch operations.
    • Selective cerebral perfusion for nondissecting thoracic aneurysms requires careful patient selection and management.
