Asymptomatic intrarenal arteriovenous fistula accompanying severe renal vein dilatation detected 30 years after percutaneous renal biopsy.
We report on a patient with asymptomatic intrarenal arteriovenous fistula (AVF) accompanying severe renal vein dilatation detected 30 years after percutaneous renal biopsy. The patient was found to have microscopic hematuria. Three-dimensional computerized tomography confirmed the presence of an AVF, and arterial embolization was performed. Three-dimensional computerized tomography is very useful and effective to image the physiology of vascular lesions for the diagnosis of a renal AVF.
