Regional perfusion during aortic arch anomaly repair is feasible and reduces complications. This technique may improve outcomes for neonates and infants undergoing complex cardiac surgery.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Medical Technology

Background:

  • Deep hypothermic circulatory arrest carries risks of neurological and myocardial injury during aortic arch anomaly repair.
  • Regional cerebral and myocardial perfusion strategies aim to mitigate these potential side effects.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of regional perfusion in neonates and infants undergoing aortic arch anomaly repair.
  • To assess the impact of regional perfusion on neurological and myocardial complications.

Main Methods:

  • A cohort of 48 neonates/infants with complex aortic arch anomalies underwent surgery using regional perfusion.
  • The technique involved arterial cannulation via the innominate artery and simultaneous myocardial perfusion.

  • Cardioplegia was administered during intracardiac repair procedures.

    • Main Results:

    • Operative mortality was 0% in Group I (coarctation/interruption with VSD) and 18.2% in Group II (complex intracardiac defects).
    • Late mortality was 0% in Group I and 11.1% in Group II.
    • Complications included low cardiac output (8 cases), transient neurological issues (2 cases), and transient renal insufficiency (2 cases).

    Conclusions:

    • Regional perfusion is a viable technique for aortic arch reconstruction, yielding acceptable results.
    • This method may decrease complications associated with circulatory arrest.
    • Complex intracardiac defects in conjunction with aortic arch repair remain associated with significant mortality and morbidity.
