Abstract

A case of renal arteriovenous fistula is presented in which radioisotope renography and differential studies of renal function strongly suggested the presence of ipsilateral renal ischemia, subsequently confirmed. Another case, due to hypernephroma, is described in which aorticorenal arteriography revealed vascular lakes within the tumor, together with marked extrarenal venous dilation. Fifty-three previously reported cases of renal arteriovenous fistula are reviewed in detail, with special attention to the relationship of diastolic hypertension to the renal and vascular pathology.
