Origin
The superior lobar arteries of the left lung are branches of the left pulmonary artery that supply the superior lobe of the left lung.
Course
As it arises from the left pulmonary artery, the superior lobar artery enters the hilum of the left lung and accompanies the left superior lobar bronchus into the superior lobe.
Branches
The superior lobar artery gives rise to three segmental arteries distally, the apical and posterior segmental arteries (via the apicoposterior segmental artery) and the anterior segmental artery (Lee et al., 1991). The lingular artery also originates from the superior lobar artery of the left lung.
Supplied Structures
The superior lobar artery supplies the bronchopulmonary segments of the superior lobe of the left lung.
