摘要："The lingular segment bronchi usually bifurcate into superior lingular (B-4) and inferior lingular (B-5) segmental bronchi. We report 32 horizontally bifurcated lingular segment bronchi cases, analyzing the bronchovascular variations and the perioperative outcomes. All patients with pulmonary lesions underwent three-dimensional computed tomography bronchography and angiography between January 2019 and January 2022. The bronchovascular patterns were analyzed for each patient. A consecutive 5280 patients were included, and 32 cases of this malformation were identified. The incidence of the lateral (B-4) and medial (B-5) lingular segmental bronchi is 0.6%. The A(4) and A(5) arise separately in 21 (65.6%) patients. In 9 (28.1%) patients, the A(4)a arises from the common trunk of A(4 + 5). In 2 (6.3%) patients, the A(4) arises from the interlobe artery, while A(5) is a mediastinal lingular artery. The common trunk of V(4)a + b is found in 19 (59.4%) patients. The V-5 is the least changeable of the segmental bronchi veins. Among the 32 patients, five patients had an LS4 segmentectomy. The surgical details of the five patients are summarized. The laterally and medially bifurcated lingular bronchus pattern is a rare anomaly. It implies that the lingular bronchus is not only superiorly and inferiorly bifurcated."
