Dynamic scintigraphy in renal arteriovenous fistula.

Radiographic contrast aortography and radionuclide dynamic scintigraphy were used to diagnose a congenital renal arteriovenous fistula in a 33 year old woman who presented with hypertension, cardiac decompensation and abdominal bruit. Since dynamic scintigraphy is a noninvasive, nontraumatic, low risk and easily repeatable procedure, it is invaluable for the diagnosis of the fistula and for monitoring patients who are managed without surgery.
