Left upper lobectomy for cancer of the left lung with a rare mediastinal left basal pulmonary artery

We report a rare case wherein a mediastinal left basal pulmonary artery was detected during surgery. Intraoperative findings revealed mediastinal left lingular and basal segments of the pulmonary artery (A4+5 + A8 −10) just dorsal to the superior pulmonary vein. The mediastinal left basal pulmonary artery is classified by its branching type, (1) complete type —wherein the entire that all basal pulmonary artery flow lies between the superior pulmonary vein and the left upper bronchus, as in like this case, (2) incomplete type—wherein that a part of the left basal pulmonary artery segment is on the flow mediastinal side. It is important to understand t his rare aberration for undergoing safe surgery.
