Arterial sleeve lobectomy for lung cancer invading chest wall.

Lung cancer is a leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) is a predominant subtype and treatment may include immunotherapy, radiotherapy, chemotherapy, and surgery. Tumors of bigger size infiltrating large bronchi and vessels require more invasive resection such as pneumonectomy. To save lung parenchyma, sleeve lobectomy can be performed in certain patients.We report the case of a patient with NSCLC infiltrating the chest wall who underwent arterial sleeve lobectomy with rib resection. Furthermore, we discuss other surgical treatment strategies.A 58-year-old female patient was admitted to the hospital in 2020 with pain in her left posterolateral chest. Radiological imaging revealed a tumor (5.0×3.5×4.8 cm) in the top of the left lung, infiltrating pulmonary artery and ribs. Therefore, left upper sleeve lobectomy together with resection of rib blocks II to V was performed. The surgery was uncomplicated, but a few weeks postoperatively, the patient experienced repeated episodes of consciousness disturbances. Contrast CT revealed a cerebral malformation in the patient who died 3.5 months after surgery.Sleeve lobectomy can be safely performed in patients with lung tumors infiltrating larger bronchi and vessels who would not tolerate pneumonectomy.
