Abstract
BackgroundThere have been a number of reports on pulmonary venous anomalies. However, most of the reports focused on the anatomical branching pattern of the peripheral pulmonary veins.Case presentationWe report a 75-year-old female whose right superior pulmonary vein V1 existed dorsal to the right main pulmonary artery and V2+3 existed dorsal to V4+5. Thus, we could not find V1 and V2+3 in the hilum just after a thoracotomy to perform right upper lobectomy for lung cancer. Thus, the right main pulmonary artery and the superior trunk (A1+3) were exposed without cutting the superior pulmonary vein.ConclusionThere has been no report so far regarding this type of pulmonary vein translocation. Preoperative three-dimensional computed tomography images were helpful to identify this variant.
Highlights
There have been a number of reports on pulmonary venous anomalies
We report an extremely rare case of translocation of the superior pulmonary vein, which was detected by preoperative three-dimensional (3D) volume rendering computed tomography (CT) images, yielding safe dissection of the pulmonary vessels during right upper lobectomy
Three-dimensional (3D)-volume rendering CT images, that was reconstructed by chest CT using commercially available software (Synapse Vincent, Fuji, Japan), showed that the right pulmonary vein V1 existed just behind the main part of the right pulmonary artery and V2+3 existed dorsal to V4+5 (Fig. 2a–c)
