Insights

Cerebral infarction in children undergoing VA ECMO may occur due to an incomplete circle of Willis. This study highlights 3 cases of cervical cannulation-related cerebral infarction potentially linked to this anatomical variation.

Area of Science:

  • Pediatric Cardiology
  • Neurology
  • Cardiovascular Surgery

Background:

  • Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is a critical support for critically ill children.
  • Cervical cannulation, using the right carotid artery and right internal jugular vein, is a common VA ECMO approach in pediatrics.
  • Cerebral infarction is a recognized complication in pediatric VA ECMO patients.

Purpose of the Study:

  • To investigate the potential link between incomplete Circle of Willis anatomy and cerebral infarction in pediatric patients undergoing VA ECMO with cervical cannulation.
  • To present clinical cases illustrating this association.

Main Methods:

  • Retrospective review of 3 pediatric cases undergoing VA ECMO with cervical cannulation.
  • Analysis of neurological outcomes, focusing on cerebral infarction.
  • Consideration of Circle of Willis patency in relation to observed complications.

Main Results:

  • Three pediatric patients developed cerebral infarction during VA ECMO with cervical cannulation.
  • The cerebral infarction in these cases is hypothesized to be associated with an incomplete Circle of Willis.
  • This anatomical variation may compromise cerebral perfusion during VA ECMO.

Conclusions:

  • An incomplete Circle of Willis may be a predisposing factor for cerebral infarction in pediatric patients receiving VA ECMO via cervical cannulation.
  • Further investigation into pre-procedural anatomical assessment is warranted.
  • Understanding this association can inform strategies to mitigate neurological injury.
