PURPOSE
To identify and clarify the comprehensive anatomic patterns in the left lower lobe (LLL).
METHODS
Using computed tomography (CT) imaging data, including that obtained using three-dimensional CT, we reviewed the anatomic patterns of the pulmonary vessels and bronchi in the left lungs of 539 patients, focusing on the LLL.
RESULTS
The two-stem type in A was observed in 131 (24.7%) patients and the three-stem type in A was observed in 11 (2.1%) patients. The independent two-stem type in B was observed in four (0.75%) patients. The B with independent branching from the basal bronchi was observed in 42 (7.9%) patients. B* was observed in 129 (24.0%) patients and B* was accompanied by A* in all patients. An extrapericardial common trunk of the left pulmonary veins was identified in five patients (0.93%).
CONCLUSION
We identified various bronchovascular patterns in the LLL of a large number of patients. Our results provide useful information for anatomic pulmonary resection, especially segmentectomy.
目的
识别并阐明左下叶（LLL）的全面解剖模式。
方法
我们使用计算机断层扫描（CT）成像数据，包括三维 CT 获得的数据，对 539 名患者的左肺肺血管和支气管的解剖模式进行了研究，重点关注 LLL。
结果
在 131 名患者（24.7%）中观察到 A 型两干型，在 11 名患者（2.1%）中观察到 A 型三干型。在 4 名患者（0.75%）中观察到独立的 B 型两干型。在 42 名患者（7.9%）中观察到从基底支气管独立分支的 B 型。在 129 名患者（24.0%）中观察到 B*，所有患者均伴有 A*。在 5 名患者（0.93%）中发现了左肺静脉的心外共同干。
结论
我们在大量患者的 LLL 中发现了各种支气管血管模式。我们的结果为解剖性肺切除术，特别是节段切除术提供了有用的信息。
