title: [Two cases of renal arteriovenous fistula].
abstract: The first case was a congenital renal arteriovenous fistula in a 33-year-old woman and the second case was a secondary renal arteriovenous fistula in a 67-year-old man. Both cases were seen with asymptomatic gross hematuria without any cardiovascular symptoms. In case 1, the arterial stage of right selective renal angiogram demonstrated a cirsoid type arteriovenous fistula in the right kidney; then, partial nephrectomy was performed. Angiogram of case 2 demonstrated arteriovenous fistula in the lower part of the right kidney. In this case arterial embolization was performed. After reviewing the literature, we believe that partial nephrectomy or arterial embolization is the most useful operative procedure to treat almost all cases of the cirsoid type renal A-V malformation. Conservative treatment of arteriovenous fistula has increased during the post 10 years.
