title: The role of angiography in the diagnosis of tracheal--innominate artery fistula.
abstract: When a tracheal-innominate artery fistula is suspected, angiography is essential if the patient's condition is stable. An aggressive  angiographic approach is needed to demonstrate the fistulous tract. Multiple injections in different degrees of obliquity and subtraction views should be obtained for early accurate diagnosis and for optimal demonstration of the pathologic anatomy.
