Description

Background. It has recently been suggested that virtual-assisted lung mapping (VAL-MAP) may enable more reliable and safer intraoperative navigation than conventional preoperative lung marking strategies. We herein report a case of thoracoscopic wedge lung resection of small-sized ground-glass nodules (GGNs) using VAL-MAP. Case. A 63-year-old man who had undergone treatment for prostate cancer presented with two small-sized peripheral GGNs in the right upper lobe. A follow-up chest CT scan of the patient nine months later demonstrated an increase in the size of the two GGNs. Due to the patient's severe renal insufficiency, we decided to perform thoracoscopic wedge lung resection using VAL-MAP. Intraoperatively, four blue markings were clearly visible on the right upper lobe, and the two lesions were successfully resected with single wedge resection along the markings as Merkmal. The pathological diagnosis was adenocarcinoma in situ. The patient's postoperative course was uneventful, and he remains well after one year, with no evidence of recurrence. Conclusions. We herein reported a case of thoracoscopic wedge lung resection of small-sized GGNs that was performed using VAL-MAP. VAL-MAP is a novel and useful strategy for detecting small-sized peripheral lung lesions with a high degree of reliability and safety.
