Echocardiography and perfusion scintigraphy in the diagnosis of pulmonary arteriovenous fistula.
The echocardiographic and perfusion scintigraphic evaluation of an adolescent boy with a pulmonary arteriovenous fistula is reported. Contrast echocardiography following the rapid intravenous injection of indocyanine green dye was utilized to document extracardiac right-to-left shunting. Perfusion lung scintigraphy demonstrated the presence of a single large pulmonary arteriovenous fistula. Contrast echocardiography and perfusion scintigraphy are minimally invasive, safe and easily performed techniques for the rapid diagnosis of pulmonary arteriovenous fistula.
