Anatomical segmentectomy for pneumothorax associated with congenital bronchial atresia

Figure 1: Chest computed tomography demonstrated a collapsed right lung and hyperinflation of the right posterior segment with mucoid impaction (arrowheads). The segmental line (arrows) between the posterior and other segments was markedly evident. Figure 2: Operative observation demonstrated a peripheral bulla formation (arrowheads) in the emphysematous area (posterior segment) of the right upper lobe, and a clear segmental line between the posterior and other segments (arrows indicate the segmental line between the apical (S1) and posterior (S2) segments).
