Abstract
Twenty-six arteriovenous fistulas were produced in mongrel puppies. Lengthening of the femur compared with the opposite untreated limb followed in almost every case. The increased growth was associated with elevation of temperature on the surface as well as in the intramedullary portion of the bone. There was a definite increase in the volume of vascular tissue in the femur as indicated by microangiograms. Venous stasis occurred in the limb distal to the arteriovenous fistula. These observations raise the question whether venous stasis was the cause of the increased rate of growth of bone in limbs following surgical preparation of an arteriovenous fistula.
