Figure 5. Current tumor marking method: A hook wire placement is performed under general anesthesia in a hybrid operating room. After the patient was intubated with a double-lumen tube under general anesthesia, the targeted tumor was identified using C-arm CT (A). A hook wire was then inserted near the targeted tumor, referring to the CT image (B). After tumor marking, the targeted tumor was resected via wedge resection.
