Peripheral congenital arteriovenous fistulae: observe, operate, or obturate?
In 1976, we presented our experience in the surgical management of patients with peripheral congenital arteriovenous fistulae (CAVF). This report updates our experience and specifically describes subsequent experience with intraarterial embolization therapy. Twenty-six infants and children with CAVFs have been treated at Children's Hospital of Los Angeles from 1966 to 1990. The majority of lesions were lower extremity (12), followed by upper extremity (8), shoulder girdle (3), and thorax/neck (3). Seventeen patients had lesions in multiple locations. All patients under 1 year of age had upper extremity lesions, all in the 5- to 10-year age group had lower extremity lesions, and all over 15 years of age at presentation required amputation. Twelve patients had initial embolization therapy and 12 had surgery. Seven of eight patients followed after embolization have improved. Embolization is not effective in large or ulcerated lesions. All patients with embolization alone have residual disease and three of eight have discrepancy in extremity length. Surgery has a 50% complication rate and 7 of 10 followed surgery patients have residual disease. Radiologic catheter techniques and embolization provide a valuable alternative therapy for CAVFs and should be used as the primary form of treatment in most cases.
