Left Lower Lobectomy in a Patient With Absence of Pulmonary Artery Branching Into the Lobe

Abstract

Here, we report a case in which we resected non-small cell lung cancer of the left lower lobe and detected an anomaly in the resected lobe. Three-dimensional computed tomography showed more detailed information on this anomaly than the conventional one. Because we recognized the information regarding the anomaly before the operation, we accomplished left lower lobectomy and an uneventful postoperative course. If carcinoma had existed in the other lobe, the intraoperative and postoperative course would have become more serious. Therefore, it is essential to pay attention to the information regarding anatomic abnormality when resecting malignant tumors.
