Deep seated giant arteriovenous malformations in infancy

Area of Science:

• Neurology
• Pediatric Cardiology
• Vascular Surgery

Background:

• Arteriovenous malformations (AVMs) involving the vein of Galen are rare congenital vascular anomalies.
• These malformations can lead to significant hemodynamic disturbances, including high-output heart failure.
• Diagnosis in infancy necessitates prompt and specialized management strategies.

Observation:

• Two infant cases of deep cerebral venous system AVMs are presented.
• One patient required a ventriculo-peritoneal shunt for obstructive hydrocephalus.
• Progressive heart failure was observed in both patients, requiring intervention.

Findings:

• Surgical intervention on the AVM was performed in one patient to manage heart failure.
• The patient not requiring a shunt was managed medically with digitalis for heart failure.
• Both cases illustrate the complex interplay between cerebral AVMs and cardiac function in infants.

Implications:

• Early diagnosis and tailored treatment are crucial for managing pediatric cerebral AVMs.
• Cerebral AVMs can present with severe systemic complications like heart failure, requiring multidisciplinary care.
• Understanding the hemodynamic impact of these AVMs informs therapeutic decision-making and improves patient outcomes.
