Congenital aortocaval fistula to the superior vena cava: a case report.

ABSTRACT

Various systemic arteriovenous fistulas have been described. The arteriovenous fistula arising from the ascending aorta and draining separately into the superior vena cava is very uncommon. The authors report a case of congenital aortocaval fistula to the superior vena cava in a 22 year-old woman in whom the fistula was closed successfully.
