Left pulmonary artery (Arteria pulmonalis sinistra)
Educational content only — not medical advice.
Anatomy
The left pulmonary artery — shorter than the right, passing in front of the left bronchus to the left hilum where superior and inferior lobar branches vascularise the lung; its relation to the descending aorta defines the aortopulmonary window on imaging.
Clinical notes
Nodes in its aortopulmonary window are staged in thoracic oncology; mediastinal mass compression may indent the artery visible on angiography.
