Summary

A 17-year-old boy developed circling and hand stereotypies after aortic coarctation repair. An MRI revealed a putaminal infarct, suggesting a link between the injury and the observed neurological symptoms.

Area of Science:

  • Neurology
  • Cardiology
  • Developmental Pediatrics

Background:

  • Aortic coarctation repair is a complex cardiovascular procedure.
  • Neurological complications can arise following cardiac surgery, particularly in pediatric patients.
  • Stereotyped movements and gait disturbances are significant neurological signs.

Observation:

  • A 17-year-old male presented with new-onset circling behavior affecting his gait.
  • Complex, stereotyped hand movements were also observed postoperatively.
  • These symptoms emerged after a complicated surgical repair of aortic coarctation.

Findings:

  • Magnetic Resonance Imaging (MRI) revealed an infarct in the right putamen.
  • The putaminal infarct is a potential cause of the observed motor and behavioral changes.

  • The patient's behavioral phenotype showed similarities to autistic traits.

    • Implications:

    • This case highlights a potential association between putaminal injury and specific neurological deficits after aortic coarctation repair.
    • Understanding these associations is crucial for managing pediatric patients with congenital heart disease.
    • Further research may elucidate the specific pathways linking putaminal damage to behavioral changes resembling autism.
