Specific Orientation of the Medial Superior Segment of the Right Lung

Description

Medial inspection of the right upper lobe highlights the superior (apical) bronchopulmonary segment and its segmental bronchus, which courses laterally from the hilum into the segment’s parenchyma. The segment sits superior to the middle lobe and anterior to the posterior segment of the upper lobe, with its medial surface relating to the mediastinum rather than the costal pleura. Along this face, the segmental pulmonary artery branch typically runs superior to the segmental bronchus, while tributaries of the superior pulmonary vein track more anterior and inferior in the intersegmental planes. Segmental boundaries are implied by connective tissue septa and venous drainage rather than by a sharp external fissure. Segmental orientation matters when you plan or interpret lung-sparing procedures. A right upper lobe segmentectomy for a small peripheral non small cell lung carcinoma hinges on correct identification of the apical segmental bronchus and artery, plus preservation of intersegmental veins that define the true surgical plane and reduce postoperative air leak. This medial perspective also supports bronchoscopy teaching, where correlating endobronchial branching with expected arterial relationships helps avoid wrong-segment sampling during transbronchial biopsy. Thoracic anatomy courses and radiology curricula can pair this artwork with CT anatomy of the right upper lobe, reinforcing how bronchopulmonary segments map to mediastinal relationships and to segmental atelectasis patterns. It also suits operative atlases and preoperative planning materials for VATS or robotic segmentectomy focused on upper lobe segmental dissection.
