Posterior Vein of the Right Lung

Description

Centered in an anterior thoracic view, the heart sits medial to the right lung hilum while the right main bronchus and its lobar divisions course posterior to the pulmonary vessels. The posterior vein of the right lung is traced as a blue venous channel emerging from the posterior aspect of the right pulmonary venous plexus, then running medially toward the left atrium as part of the right pulmonary venous drainage. Superior and inferior pulmonary veins are suggested by their typical orientation at the hilum, with pulmonary arteries (red) positioned more superiorly, and the trachea bifurcating superior to the great vessels. Tracing the posterior venous tributaries matters when you need to teach, or plan around, the layered arrangement of the right hilum (bronchus posterior, pulmonary artery superior, pulmonary veins anterior and inferior) and how it changes as vessels converge on the left atrium. This is the venous anatomy that becomes relevant in right-sided pulmonary resection, where segmental and lobar veins can be misidentified, risking venous congestion of preserved segments after a right upper lobectomy or a lower-lobe segmentectomy. It also supports interpretation of contrast-enhanced CT and catheter-based procedures, where pulmonary venous variants and posteriorly coursing veins can complicate mapping for atrial fibrillation ablation at the pulmonary vein ostia. Small structure, big consequences. Use this illustration in cardiothoracic anatomy teaching, radiology correlation figures for pulmonary venous phase CT, and surgical atlases covering VATS or open hilar dissection on the right. It also fits physiology modules that pair airway branching with pulmonary vascular return to the left atrium. Anatomical accuracy verified by SciePro's Medical Advisory Board.
