Abstract
Virtual-assisted lung mapping (VAL-MAP) is a bronchoscopic multi-spot dye-marking technique with the aid of virtual images (virtual bronchoscope and virtual 3D images) without or with microcoil marking inside the lung (VAL-MAP 2.0). It is beyond the concept of conventional localization; it helps to navigate surgery to determine the most appropriate resection lines to secure resection margins. There are five steps in VAL-MAP (mapping design, actual bronchoscopic mapping, post-mapping CT, 3D reconstruction, and surgery), which might seem complex first but once accustomed, it is not. VAL-MAP can be applied for wedge resection (e.g., hardly identifiable small ground-glass nodules) or segmentectomy, especially extended or very complex segmentectomy and combined subsegmentectomy. VAL-MAP 2.0 is useful for deep wedge resection or for segmentectomy to confirm a deep resection line along the accurate intersegmental plane. Electromagnetic navigation bronchoscope can also be used in VAL-MAP.
