PURPOSE: This retrospective study was performed in order to determine if patients with very severe chronic obstructive pulmonary disease (COPD) have larger main bronchi than patients with less severe disease. METHODS: Charts of patients having had a spirometric evaluation of their COPD and a digitized thin-slice computed tomography (CT) scan between January 2004 and September 2007 were reviewed. Adequate CT scans of male patients [i.e., those allowing a multiplane reconstruction (MPR) of the upper tracheobronchial tree using a double orthogonal oblique method] were divided into two groups: group 1 [forced expiratory volume in 1 s (FEV(1)) ranging from 30% to 80%] and group 2 (FEV(1) < 30%). RESULTS: Intraobserver and interobserver coefficients of repeatability were 1.79 and 2.51 mm, respectively. Median values and interquartile ranges of minimum right main bronchial diameter were 11.0 (9.6-12.7) mm versus 12.7 (10.8-13.9) mm in groups 1 (27 patients) and 2 (10 patients), respectively (P = 0.048); values for the minimum left main bronchial diameter were 10.7 (8.9-11.9) mm versus 11.8 (11.2-12.4) mm in groups 1 and 2, respectively (P = 0.040). The difference between the groups in median values of the minimum right and left main bronchial diameters was 1.2 mm. Other values were similar in both groups. CONCLUSION: The difference in minimum main bronchial diameters between our two groups corresponded to a difference of two or three sizes of a double-lumen tube. This difference must be taken into account for tube selection for such patients. Further studies are needed to prove that CT scan MPR can improve patients' intraoperative care.
