BACKGROUND
For thoracic surgeons, three-dimensional computed tomography bronchography and angiography (3-DCTBA) is a convenient way to analyze pulmonary variations before segmentectomy. Mediastinal lingular artery (MLA) is one of the representative variations.
METHODS
The 3-DCTBA data of left upper lobe (LUL) were collected from patients who underwent pulmonary surgery from January 2018 to December 2019. We reviewed the patterns of bronchi and pulmonary vessels and grouped them according to different classifications.
RESULTS
Among all the 404 cases of 3-DCTBA, mediastinal lingular artery (MLA) was found in 107 cases (26.49%). The patterns of B and the vein in left upper division (LUD) are distinct between mediastinal (M-type) group and interlobar (IL-type) group. The patterns of bronchi and veins in lingular division, as well as the pattern of pulmonary artery in LUD, have no differences between M-type and IL-type groups.
CONCLUSIONS
Mediastinal lingular artery is speculated to originate from the variation of B, and the MLA independently influences the venous pattern in LUD in turn.
背景
对于胸外科医生来说，三维计算机断层支气管血管造影术（3-DCTBA）是在段切除术前分析肺变异的一种便捷方式。纵隔舌动脉（MLA）是一种具有代表性的变异。
方法
收集 2018 年 1 月至 2019 年 12 月接受肺手术的患者的左肺上叶（LUL）3-DCTBA 数据。我们回顾了支气管和肺血管的模式，并根据不同的分类进行了分组。
结果
在所有 404 例 3-DCTBA 中，发现纵隔舌动脉（MLA）107 例（26.49%）。纵隔型（M 型）组和叶间型（IL 型）组左肺上叶支气管（B）和静脉（LUD）的模式明显不同。舌段支气管和静脉的模式以及 LUD 中肺动脉的模式在 M 型和 IL 型组之间没有差异。
结论
推测纵隔舌动脉可能起源于 B 的变异，而 MLA 则独立地影响 LUD 中的静脉模式。
