Selective cerebral perfusion (SCP) improves outcomes for aortic arch replacement, reducing mortality and neurologic complications. This technique is crucial for managing complex aortic arch aneurysms and dissections.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Thoracic Surgery

Background:

  • Aortic arch replacement is a complex procedure with significant risks.
  • Selective cerebral perfusion (SCP) is a technique used to mitigate these risks.
  • Clinical experience with SCP in aortic arch surgery needs further reporting.

Purpose of the Study:

  • To report clinical experience with aortic arch replacement using SCP.
  • To identify predictors of in-hospital mortality and neurologic outcomes.
  • To evaluate the efficacy of SCP in complex aortic arch procedures.

Main Methods:

  • A retrospective study of 472 patients undergoing aortic arch replacement with SCP.
  • Operations utilized hypothermic extracorporeal circulation and SCP.

  • Data collected on patient demographics, etiologies of aortic disease, and outcomes.

    • Main Results:

    • Overall in-hospital mortality was 9.3%, decreasing to 4.1% in recent cases.
    • Predictors of mortality included early series, ischemia, pump time, age, renal dysfunction, and prior CVA.
    • Neurologic dysfunction rates were 4.7% temporary and 3.2% permanent; CVA history predicted temporary dysfunction, while CVA and pump time predicted permanent dysfunction.

    Conclusions:

    • SCP facilitates complex aortic arch replacement.
    • The technique leads to reduced mortality and morbidity for aortic arch aneurysms and dissections.
    • SCP is a valuable adjunct for improving outcomes in challenging aortic arch surgeries.
