This study introduces a novel cerebral protection technique using cooled blood during aortic surgery. The method shows promise for effective brain protection without causing blood clotting issues.

Area of Science:

  • Cardiovascular Surgery
  • Neurology
  • Hypothermia Research

Background:

  • Aortic arch aneurysm repair necessitates robust cerebral protection strategies.
  • Maintaining adequate blood flow and temperature to the brain is critical during complex aortic surgeries.
  • Existing methods for cerebral protection may carry risks such as coagulation disorders.

Observation:

  • A new technique for retrograde cerebral perfusion was developed.
  • Blood for perfusion was cooled to 10°C.
  • Moderate systemic hypothermia was maintained concurrently.

Findings:

  • The technique was successfully applied in two patients undergoing ascending and aortic arch graft replacement for dissecting aneurysms.
  • Excellent cerebral protection was achieved.

  • No coagulation disorders were observed in the patients.

    • Implications:

    • This innovative cooling method offers a potentially safer alternative for cerebral protection during aortic surgery.
    • It may reduce the incidence of neurological complications and coagulopathy.
    • Further research is warranted to validate its efficacy in a larger patient cohort.
