Video clip is available online.A 52-year-old woman, without any history of medical diseases, presented with ground-glass opacity in the anterior segment (LS3) of the left upper lung (Figure 1) incidentally found during a health examination. Her preoperative electrocardiogram (ECG), pulmonary function, and cardiac echography were normal. She underwent video-assisted thoracoscopic (VATS) left upper anterior segmentectomy. As planned, the segmental artery and intrasegmental vein to the anterior segment of the left upper lobe were identified and divided, and the segmental bronchus was looped and ligated with a silk tie. To recognize the intersegmental plane, FIGURE 1. A 15-mm ground-glass opacity that was confirmed to be lung adenocarcinoma was found on the low-dose computed tomography study.VIDEO 1. Air was instilled through a 23-gauge butterfly needle into the distal part of the segmental bronchus to inflate the target segment (1-20 seconds). Subsequently, concurrent bubble streaming in the intersegmental veins was noticed (21-34 seconds). Intracardiac injection of 1-mg epinephrine was administered at 54 seconds, and the heart resumed beating within 1 minute.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
