Simple Summary: Surgery for centrally located lung cancer after previous cancer treatments can be challenging due to the lungs adhering to the chest wall. We investigated whether using the Cavitron Ultrasonic Surgical Aspirator (CUSA) could help. We focused on patients who had thoracoscopic salvage anatomic lung resections after systemic or radiotherapy with and without CUSA. The CUSA group took more time for surgery but had less bleeding. Our analysis found that older age carried more risk for complications, and using CUSA decreased bleeding, whereas radiotherapy increased the risk of bleeding. CUSA seems to prevent harm to blood vessels and airways, which could lead to less bleeding during this specific type of minimally invasive lung cancer surgery. In centrally located lung tumors, salvage pulmonary resections pose challenges due to adhesions between the pulmonary parenchyma, chest wall, and hilum. This study aimed to investigate the surgical outcomes associated with Cavitron Ultrasonic Surgical Aspirator (CUSA) usage in thoracoscopic salvage pulmonary resections. Patients with centrally located advanced-stage lung tumors who underwent salvage anatomic resections following systemic or radiotherapy were included. They were categorized into CUSA and non-CUSA groups, and perioperative parameters and surgical outcomes were analyzed. Results: The study included 7 patients in the CUSA group and 15 in the non-CUSA group. Despite a longer median surgical time in the CUSA group (3.8 h vs. 6.0 h, p = 0.021), there was a significant reduction in blood loss (100 mL vs. 250 mL, p = 0.014). Multivariate analyses revealed that the use of CUSA and radiotherapy had opposing effects on blood loss (β: −296.7, 95% CI: −24.8 to −568.6, p = 0.034 and β: 282.9, 95% CI: 19.7 to 546.3, p = 0.037, respectively). In conclusion, while using CUSA in the salvage anatomic resection of centrally located lung cancer may result in a longer surgical time, it is crucial in minimizing blood loss during the procedure.
