We herein report a rare case of an antero-basal pulmonary artery that was noticed during left upper lung lobectomy. A 61-year-old man underwent surgery and radiation for a brain tumor, which was diagnosed as a solitary metastasis of the primary lung cancer in the upper lobe of the left lung. He underwent left upper lobectomy for the lung cancer. During the operation, the left A4+5 and A8b+9+10 was found to be diverged from the main left pulmonary artery as the first branch, which descended between the left upper pulmonary vein and the left upper bronchus. The left upper lobe was successfully resected with preserving the A8b+9+10. This variation was not recognized preoperatively. Careful dissection along the pulmonary vessels is essential to prevent cutting off the unexpected aberrant anatomy.
我们在此报告一例左上肺叶切除术中发现的罕见的前基底肺动脉病例。一名61岁男性因脑肿瘤接受了手术和放疗，该脑肿瘤被诊断为左肺上叶原发性肺癌的孤立性转移。他因肺癌接受了左上肺叶切除术。手术过程中，发现左A4+5和A8b+9+10作为第一分支从左肺动脉主干分出，下行于左上肺静脉和左上支气管之间。在保留A8b+9+10的情况下成功切除了左上叶。这种变异术前未被识别。沿肺血管仔细解剖对于防止切断意外的异常解剖结构至关重要。
