Origin

The basal part of the left pulmonary artery is a continuation of the inferior lobar artery, after it gives off its superior segmental artery.

Course

The basal part of the inferior lobar artery extends into the inferior lobe of the left lung, accompanied by the inferior lobar bronchus.

Branches

The basal part of the left pulmonary artery gives rise to numerous branches. Firstly, the anterior and medial branches arise from a common trunk, the anteromedial basal segmental artery, in 60% of individuals (Lee et al., 1991). This trunk gives rise to the anterior and medial basal segmental arteries. The lateral and posterior basal segmental arteries arise directly from the basal part of the left pulmonary artery.

Supplied Structures

The basal part of the left pulmonary artery supplies blood to the basal part of the inferior lobe of the left lung.
