There is a risk of unexpected injuries to bronchi and blood vessels when patients with such anomalies undergo surgery for lung cancer.\n <\/jats:p>\n <\/jats:sec>\n \n Case presentation<\/jats:title>\n \n 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 B\n 1\u00a0+\u20092<\/jats:sup>\n and hyperlobulation between S\n 1\u00a0+\u20092<\/jats:sup>\n and S\n 3<\/jats:sup>\n , while the interlobar fissure between S\n 1\u00a0+\u20092<\/jats:sup>\n and S\n 6<\/jats:sup>\n was completely fused. Three-dimensional computed tomography (3D-CT) revealed an anomalous V\n 1\u00a0+\u20092<\/jats:sup>\n joining the left inferior pulmonary vein and a branch of the V\n 1\u00a0+\u20092<\/jats:sup>\n running between S\n 1\u00a0+\u20092<\/jats:sup>\n and S\n 6<\/jats:sup>\n . 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 V\n 1\u00a0+\u20092<\/jats:sup>\n and confirm the locations of B\n 1\u00a0+\u20092<\/jats:sup>\n and B\n 6<\/jats:sup>\n when dividing the fissure.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n The aim of the surgical procedure performed in this case was to divide the fissure between S\n 1\u00a0+\u20092<\/jats:sup>\n 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.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1186\/s13019-021-01392-3","type":"journal-article","created":{"date-parts":[[2021,1,21]],"date-time":"2021-01-21T05:04:30Z","timestamp":1611205470000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Lobectomy for lung cancer with a displaced left B1 + 2 and an anomalous pulmonary vein: a case report"],"prefix":"10.1186","volume":"16","author":[{"given":"Shinichi","family":"Sakamoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromitsu","family":"Takizawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoya","family":"Kawakita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Tangoku","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,1,21]]},"reference":[{"key":"1392_CR1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.5761\/atcs.ra.12.02174","volume":"19","author":"N Ikeda","year":"2013","unstructured":"Ikeda N, Yoshimura A, Hagiwara M, Akata S, Saji H.
