Novel locally nebulized indocyanine green for simultaneous identification of tumor margin and intersegmental plane.

Background: Segmentectomy, recommended for early-stage lung cancer or compromised lung function, demands precise tumor detection and intersegmental plane identification. While indocyanine green (ICG) commonly aids in these aspects using near-infrared imaging, its separate administrations through different routes and times can lead to complications and patient anxiety. This study aims to develop a lung-specific delivery method by nebulizing low-dose ICG to targeted lung segments, allowing simultaneous detection of lung tumors and intersegmental planes across diverse animal models.

Segmentectomies involving the posterior basal segment (S10) of the lower lobe present a challenging surgical procedure due to anatomical complexities, especially when lesions extend towards the lateral basal segment (S9). We introduce a combined subsegmentectomy technique via a posterior approach for a lesion situated between S9b and S10b, which preserves subsegmental branches that do not affect the resection margin of the tumour and facilitates intersegmental division without extending dissection into the interlobar region. This technique, the goal of which is to reduce the extent of dissection and complex stapling, is expected to minimize pulmonary complications and intrathoracic adhesions without compromising oncological outcomes.

Objective: To optimize surgical outcomes and minimize complications in complex segmentectomy of the left upper lobe, we investigated the topographical anatomy of the left upper lobe and developed a segmentectomy-oriented anatomical model.
Methods: A state-of-the-art 3-dimensional computed tomography workstation was used to visualize the intersegmental planes and associated veins to categorize the anatomical patterns influencing surgical procedures during left upper lobe segmentectomy. This included the central vein affecting S (apicoposterior segment) segmentectomy, the transverse S (anterior segment) affecting S segmentectomy, and other venous branching patterns in 395 patients who underwent thoracic surgery at our institution.

Background: To investigate the distribution pattern of V d in the left superior pulmonary vein and its clinical significance.
Methods: A retrospective analysis was conducted using three-dimensional computed tomographic bronchography and angiography (3D-CTBA) data from 500 lung cancer patients. Statistical analyses were performed to evaluate the incidence and drainage patterns of the three sub-branches of V d, namely V d1, V d2 and V d3.

Background: With the prevalence of three-dimensional computed tomography bronchography and angiography (3D-CTBA) and the development of anatomical segmentectomy, several studies have analyzed the branching patterns of peripheral segmental arteries in the right upper lobe (RUL). Nevertheless, the detailed classification of the branching patterns of the interlobar artery and the artery crossing intersegmental planes remains unknown. Thus, we conducted a retrospective study to analyze the variations of the interlobar artery and the artery crossing intersegmental planes in the RUL using 3D-CTBA.
