The lingular bronchus originates from the bifurcation of the upper lobe bronchus and has a short course before it enters the parenchyma (◘ Fig. 16.1a).

The main supply to the lingula comes from the lingular trunk, which originates from the anterior aspect of the pulmonary artery within the fissure and splits into two segmental branches. In some patients, an additional lingular artery arises from the truncus anterior (◘ Fig. 16.1b).

The lingular vein is the lowermost tributary of the superior pulmonary vein. It is easily recognizable when the superior pulmonary vein has three major roots (V¹⁺², V³, and lingula) (◘ Fig. 16.1c). However, in some patients, there are actually multiple radiating venous branches. In these cases, it is safer to divide only the lowermost branch. Once the lingula will become mobile thanks to the arterial and bronchial division, the venous drainage will become more apparent.
