Description
Background: A displaced left B1 + 2 accompanied by an anomalous pulmonary vein is a rare condition involving complex structures. There is a risk of unexpected injuries to bronchi and blood vessels when patients with such anomalies undergo surgery for lung cancer.
Case presentation: A 59-year-old male with suspected lung cancer in the left lower lobe was scheduled to undergo surgery. Chest computed tomography revealed a displaced B1 + 2 and hyperlobulation between S1 + 2 and S3, while the interlobar fissure between S1 + 2 and S6 was completely fused. Three-dimensional computed tomography (3D-CT) revealed an anomalous V1 + 2 joining the left inferior pulmonary vein and a branch of the V1 + 2 running between S1 + 2 and S6. We performed left lower lobectomy via video-assisted thoracic surgery, while taking care with the abovementioned anatomical structures. The strategy employed in this operation was to preserve V1 + 2 and confirm the locations of B1 + 2 and B6 when dividing the fissure.
Conclusion: The aim of the surgical procedure performed in this case was to divide the fissure between S1 + 2 and the inferior lobe to reduce the risk of an unexpected bronchial injury. 3D-CT helps surgeons to understand the stereoscopic positional relationships among anatomical structures.
