Acute neurologic complications after pediatric cardiac catheterization occur in 0.38% of cases. Risk factors include prolonged procedures, with embolism and hypoxia being key causes of brain injury.

Area of Science:

  • Pediatric Cardiology
  • Neuroscience
  • Medical Complications

Background:

  • Congenital heart disease (CHD) necessitates cardiac catheterization in children.
  • Cardiac catheterization, while diagnostic and therapeutic, carries potential risks.
  • Neurologic complications following these procedures require careful evaluation.

Purpose of the Study:

  • To determine the incidence of acute neurologic complications in children undergoing cardiac catheterization for congenital heart disease.
  • To identify the types of neurologic complications observed.
  • To explore the risk factors and potential mechanisms underlying these complications.

Main Methods:

  • Retrospective analysis of cardiac catheterization procedures in a university cardiac center.

  • Inclusion of children with acyanotic and cyanotic congenital heart disease.
  • Documentation and categorization of all reported acute neurologic complications.

    • Main Results:

    • An incidence of 0.38% (14 of 3,648 procedures) for acute neurologic complications was observed.
    • Common complications included seizures, stroke, and intracranial hemorrhage.
    • Prolonged procedure duration and interventional manipulation were identified as main risk factors.

    Conclusions:

    • Neurologic complications are infrequent but significant following pediatric cardiac catheterization.
    • Cerebral embolism and hypoxia are primary mechanisms of brain injury.
    • While stroke prognosis is often good, hypoxic-ischemic encephalopathy can lead to severe sequelae like developmental delay and epilepsy.
