Usefulness of selective contrast echocardiography and selective scintigraphy for the evaluation of pulmonary arteriovenous fistula in a patient with systemic arterial supply to a normal lung

To determine a surgical procedure for the correction of a systemic arterial supply to a normal lung, it is important to evaluate whether the patient has a pulmonary arteriovenous fistula. In this article, the authors report for the first time a patient in which selective contrast echocardiography and selective perfusion scintigraphy from an abnormal artery clearly demonstrated and quantified the pulmonary arteriovenous fistula. The authors believe that these methods are useful in determining the appropriate operative procedure for this condition.
