Superior lingular artery of left lung

Arteria lingularis superior pulmonis sinistri

  • Latin synonym: Ramus superior arteriae lingularis
  • Synonym: Ramus superior of lingular artery
  • Related terms: Superior lingular artery

Definition

The segmental pulmonary arteries of left upper lobe are:

  • Apical segmental artery of left lung (A1)

  • Anterior segmental artery of left lung (A2)

  • Posterior segmental artery of left lung (A3)

  • Inferior lingular artery of left lung (A4)

  • Superior lingular artery of left lung (A5)  

 

Anatomic variations on the left are far more common than on the right. Number of pulmonary arterial branches to the left upper lobe vary from 2 to 7. Most commonly, the apicoposterior and anterior segments receive blood supply from an apicoanterior trunk. In some cases, the arteries for apical, anterior and posterior segments originate separately. In 80% of cases, lingula is supplied by one branch of the pulmonary artery, which gives off arteries for superior and inferior segments
