title: Acquired arteriovenous fistulas of the scalp in hemophiliacs.
abstract: The development of arteriovenous fistulas following multiple intravenous infusions in hemophiliacs has been previously reported. In this report, we discuss two patients in whom arteriovenous fistulas developed following the use of scalp veins as sites of infusion. Because of the rich vascularity of this area and the proximity of the arterial and venous systems we recommend that this site not be used for factor infusion.
