title: A reasoned approach to a case of suspected arteriovenous fistula.
abstract: The case of an 82-year-old female patient with severe tricuspid regurgitation come to the authors' observation for suspected arteriovenous fistula, is reported. Color-Doppler US was performed for re-evaluation. It documented the presence of systemic venous and portal pulsatility associated with severe ectasia and varicosity of infracardiac systemic venous system due to systemic venous hypertension. Color-Doppler study allowed a correct diagnostic approach, excluding the presence of an arteriovenous fistula.
