Specific Anatomy of the Right Lung

Description

Oriented to the medial (hilar) aspect of the right lung (pulmo dexter), the illustration isolates the apical segment of the superior lobe (segmentum apicale, S1) in color at the superiormost portion of the lung. Superiorly it rises above the level of the first rib into the root of the neck, while inferiorly it borders the remaining superior-lobe segments that slope toward the oblique fissure. Medially, the segment faces the mediastinum near the hilum, where segmental bronchi and pulmonary vessels enter and exit, while its lateral surface would normally conform to the inner thoracic wall. Segmental boundaries follow bronchopulmonary anatomy rather than fissures. Segment-level anatomy matters when you are planning lung-sparing resections. The apical segment is a frequent target for segmentectomy in small peripheral non small cell lung cancers and for localized disease, and its relationship to the superior lobar bronchus and upper-lobe pulmonary arterial branches determines whether a VATS approach can preserve adjacent segments without compromising margins or perfusion. On cross-sectional CT and bronchoscopy, S1 is also a key landmark when tracking upper-lobe consolidation, post-obstructive atelectasis, or cavitary disease such as reactivation tuberculosis, which often favors the apical and posterior upper-lobe segments due to higher oxygen tension. Clear orientation prevents right-left errors in procedural planning. Use this artwork in thoracic anatomy teaching, pulmonary segment mapping exercises, and operative atlases illustrating right upper-lobe segmentectomy, bronchoscopy navigation, or radiology correlation for the upper lung field. It also fits patient-facing materials explaining targeted resection versus lobectomy. Anatomical accuracy verified by SciePro's Medical Advisory Board.
