Compression of the trachea by the innominate artery in a 2-month-old child.

SUMMARY. We utilized improved methods for assessing airway structure and function to define the clinical significance of the innominate artery syndrome. Both infant pulmonary function tests (IPFT) and noninvasive controlled ventilation computed tomography (CVCT) were used, along with traditional diagnostic techniques in a 2-month-old child with compression of the trachea by the innominate artery. These tests provided objective documentation of functional impairment before surgery and improvement postoperatively. These tests should aid in the understanding of this controversial syndrome and help to further define treatment options. Copyright 2001 Wiley-Liss, Inc.
