Fig 1 Computed tomographic findings of each drainage course of the UVPBI (arrowheads): (A) superior pulmonary vein group, (B) inferior pulmonary vein (IPV) group, and (C) superior segmental vein (V6) group. (BSV = basal segmental vein; UVPBI = right upper lobe vein posterior to the bronchus intermedius.)

Fig 2 Anatomical schema of each group: superior pulmonary vein (SPV) group, inferior pulmonary vein (IPV) group, and superior segmental vein (V6) group. (AV = azygos vein; BI = bronchus intermedius; BSV = basal segmental vein; E = esophagus; LA = left atrium; PA = pulmonary artery; SVC = superior vena cava; ULB = upper lobe bronchus; UVPBI = right upper lobe vein posterior to the bronchus intermedius.)

Fig 3 Operative view after a right lower lobectomy in a patient with a right upper lobe vein posterior to the bronchus intermedius (UVPBI) (case 8 [see Table 2], superior pulmonary vein group). (BI = bronchus intermedius; Bs = bronchial stump; PAs = pulmonary arterial stumps; UL = upper lobe.)
