[Giant congenital paravertebral arteriovenous fistulas in children]

Area of Science:

• Vascular Surgery
• Pediatric Cardiology
• Congenital Abnormalities

Background:

• Giant congenital paravertebral arteriovenous fistulas are rare vascular malformations.
• Understanding their embryologic origins is crucial for diagnosis and management.

Observation:

• Six pediatric cases of giant congenital paravertebral arteriovenous fistulas were analyzed.
• Presentations included jugulocarotid, vertebral artery-jugular vein, thoracic, and subclavian fistulas.
• One neonate case resulted in mortality.

Findings:

• The study describes the principal embryologic and clinical features of these complex anomalies.
• Varied anatomical locations and presentations were observed.
• The mortality in one neonate highlights the potential severity.

Implications:

• This case series informs the differential diagnosis of congenital vascular lesions in children.
• It provides insights into the management of paravertebral arteriovenous fistulas.
• The discussion on surgical versus embolization treatment, considering new materials, aids clinical decision-making.
