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

We utilized improved methods for assessing airway structure and function to define the clinical significance of the innominate artery syndrome. Both i nfant pulmonary function tests (IPFT) and noninvasive controlled ventilatio n computed tomography (CVCT) were used, along with traditional diagnostic t echniques in a 2-month-old child with compression of the trachea by the inn ominate artery. These tests provided objective documentation of functional impairment before surgery and improvement postoperatively. These tests shou ld aid in the understanding of this controversial syndrome and help to furt her define treatment options. (C) 2001 Wiley-Liss, Inc.
