Arteriovenous aneurysm of kidney after open renal biopsy

Renal arteriovenous fistula following percutaneous renal biopsy is being reported frequently in the literature. For this reason, open renal biopsy has gained popularity as a safer alternative procedure. We present a case of a large arteriovenous fistula seen two years after open renal biopsy. The presentation was highly atypical, mimicking an acute gastrointestinal event, rather than sudden hemorrhage in a previously asymptomatic fistula.
