RESUMO
Combined variation of bronchus and pulmonary vein is rare. We report the case of a 32-year-old man with lung adenocarcinoma in whom three-dimensional computed tomography bronchography and angiography displayed a unique anatomic variation in the right upper lobe. The posterior subsegmental bronchi originated from the apical segmental bronchus and the anterior segmental bronchus, respectively; the apical subsegmental vein shared a trunk with the posterior subsegmental vein. Based on this discovery, combined pulmonary segmentectomy was performed accurately.

BACKGROUND: Anatomic variation may increase the difficulty and risk of anatomic segmentectomy. The preoperative three-dimensional computed tomography bronchography and angiography (3D-CTBA) can provide a detailed model of the segmental structure, and contribute to precise and safe segmentectomy. CASE PRESENTATION: This is a case of anomalous bronchi and pulmonary vessels in the right upper posterior segment (RS2). Under the guidance of 3D-CTBA, anatomic RS2 segmentectomy was performed accurately and safely. The postoperative condition was uneventful. CONCLUSIONS: This rare case highlights the importance of 3D-CTBA to guild accurate segmentectomy with anatomic variation.
