Intraoperative Diagnosis of Bilateral Upper Limb Arteriovenous Fistulae in a Child: A Case Report.

Arteriovenous fistulae have not been extensively reported in pediatric patients and are rare for pediatric anesthesiologists to encounter in their routine practice. Awareness of these lesions enables clinicians to avoid giving medications through the anomalous vascular connections. We report a child scheduled for an excision of a sacrococcygeal mass in whom we incidentally diagnosed the presence of arteriovenous fistulae in both his upper limbs. The affected limbs should be avoided and the vessels of the lower limbs should be cannulated for administration of fluid and medications during surgery.
