Abstract：
UNASSIGNED: Catheter-based interventions have emerged for both acute and chronic pulmonary thromboembolic disease. With this development and the need for segmental cannulation, anatomic understanding of pulmonary arterial segmental branch origination is important. We aim to describe the prevalence of different pulmonary arterial segmental branch origination patterns.
UNASSIGNED: This study included 179 consecutive patients who underwent bilateral nonselective invasive pulmonary angiography for the evaluation of chronic thromboembolic pulmonary hypertension.
UNASSIGNED: In our study population (age, 59.0 ± 14.8 years, 55.3% female, 71% White), we found several anatomic variations of branches to the different lobes. These included 7 branching patterns in the right upper lobe, 3 in the right middle lobe, and 10 in the right lower lobe (4 patterns for the origin of the superior segmental artery and 6 for the origin of the basilar segmental arteries). On the left side, we found 8 patterns in the left upper lobe, with 5 involving lingular branches, and 9 in the left lower lobe (5 for the origin of the superior segmental artery and 4 for the basilar segmental pulmonary arteries). Although there were many variations, only 2-3 variations for each individual lobe accounted for >90% of the angiograms.
UNASSIGNED: Up to 3 anatomic branching patterns per lobe were noted to account for >90% of pulmonary artery branching variations in this study. This knowledge is not only useful for the interventionalist performing catheter-directed therapies but also for future research efforts that aim to standardize reporting of pulmonary angiographic findings.

摘要：
■针对急性和慢性肺血栓栓塞性疾病，已经出现了基于导管的干预措施。随着这种发展和分段插管的需要，对肺动脉节段分支起源的解剖学认识很重要。我们旨在描述不同肺动脉节段分支起源模式的患病率。
■这项研究包括179名连续患者，他们接受了双侧非选择性有创肺动脉造影以评估慢性血栓栓塞性肺动脉高压。
■在我们的研究人群中（年龄，59.0±14.8年，55.3%女性，71%白色)，我们发现了不同叶的分支的一些解剖变异。其中包括右上叶的7个分支模式，3在右中叶，右下叶10个（上段动脉起源为4个模式，基底段动脉起源为6个模式）。在左边,我们在左上叶发现了8种模式,有5个涉及舌枝，左下叶9个（上段动脉起源5个，基底段肺动脉起源4个）。虽然有很多变化，每个肺叶只有2-3个变异,占血管造影照片的90%以上.
■在这项研究中，每个肺叶多达3种解剖分支模式占肺动脉分支变异的90％。这些知识不仅对进行导管导向治疗的介入医生有用，而且对旨在标准化肺血管造影结果报告的未来研究工作也有用。
