Pseudotumor cerebri following an atrial septal defect repair in a child

Area of Science:

• Pediatric Neurology
• Cardiovascular Surgery
• Ophthalmology

Background:

• Pseudotumor cerebri (PTC), or benign intracranial hypertension, is uncommon in children.
• Altered cranial venous drainage is a known risk factor for PTC development.
• Open-heart surgery for atrial septal defect (ASD) repair is a common pediatric procedure.

Observation:

• A 7-year-old child developed symptoms of PTC 18 days post-open-heart surgery for ASD repair.
• The child's clinical presentation included signs and symptoms consistent with elevated intracranial pressure.
• No other predisposing factors for PTC were identified in this patient.

Findings:

• This case represents the first documented instance of PTC occurring in a pediatric patient following open-heart surgery.
• The temporal association suggests a possible connection between the surgical intervention and the subsequent development of PTC.
• Further investigation into potential mechanisms, such as venous drainage alterations, is warranted.

Implications:

• This case underscores the importance of considering PTC in pediatric patients presenting with neurological symptoms after cardiac surgery.
• It may prompt further research into the relationship between cardiovascular procedures and intracranial pressure regulation in children.
• Clinicians should maintain a high index of suspicion for PTC in this specific patient population.
