    Abstract:
    UNLABELLED: Bronchoscopy is the diagnostic gold standard in patients with airway malformations. Helical CT scan has produced studies such as virtual bronchoscopy or 3-D reconstruction of the airway. The purpose of this study is to analyze the correlation between fiberoptic bronchoscopy, virtual bronchoscopy and 3-D reconstruction of the airway in patients with airway malformations. METHODS: From January 2001 to March 2002 we evaluated the airway of 17 patients with airway malformations by means of a diagnostic protocol consisting on fiberoptic bronchoscopy, and Helical CT scan with 3-D reconstruction of the airway and virtual bronchoscopy. The radiologist had no access to bronchoscopic information. Age at study, associated cardiovascular anomalies, indications, localization, degree of diagnostic concordance, etiology and influence in treatment were analyzed. RESULTS: 20 studies were done to 17 patients whose mean age was 1.64 +/- 0.48 years (7 days-7 years). Twelve patients had associated anomalies of the aorta, pulmonary arteries or supraortic vessels. Excellent concordance was obtained in 13 cases (65%), good in 6 (30%) and poor in one (5%). 3-D reconstruction of the airway and adjacent vascular structures provided additional information in 14 cases (70%): in 3 exact length of the tracheal lesion and in 11 defined the cause of the compression. In all the cases, absolute concordance in localization was obtained. CT scan information modified treatment in 6 patients (35%). In 7 patients with associated vascular anomalies, no further image studies were done, confirming the anatomy concordance during surgery. CONCLUSIONS: 3-D reconstruction of the airway and virtual bronchoscopy are excellent diagnostic tools in patients with airway malformations, and contribute to define the etiology, length and diameter of the lesion. Excellent diagnostic correlation was obtained between analogic and virtual bronchoscopies, although further multicentric studies should be conducted.
