title: Giant high-flow renal arteriovenous fistula treated by percutaneous embolization.
abstract: We report the case of a giant renal arteriovenous fistula after renal biopsy in a 30-year-old man with hematuria and hypertension. We performed percutaneous endovascular embolization using macrocoils to exclude the fistula. The patient made an uneventful recovery with no further hematuria and progressive reduction of blood pressure. Follow-up by digital subtraction angiography (DSA) at 6 months showed complete occlusion of the fistula with no evidence of renal parenchymal infarction. Although giant renal arteriovenous fistulas are generally treated by nephrectomy, this case shows that embolization is a reasonable alternative to surgery.
