In this study, we aimed to reveal the normal anatomy and variations of the bronchial arterial system and to determine the sex distribution of these variations by retrospectively reviewing the images of patients who underwent thoracal multidetector computed tomographic angiography for various reasons.
Multidetector computed tomographic images of a total of 208 patients (151 men; mean age, 59 years) were retrospectively reviewed to assess the normal anatomy and variations of the bronchial arterial system.
A total of 531 bronchial arteries (median, 3; minimum, 1; maximum, 5; mean, 2.5) were detected. The number (mean diameter) of the right bronchial arteries were higher than the left bronchial arteries (290 [1.43 mm] and 241 [1.26 mm], respectively; P < .05 for both number and diameter). The mean number (diameter) of the bronchial arteries were higher with men than with women (2.58 [1.45 mm] and 2.47 [1.32 mm], respectively; P < .05 for both number and diameter). The most common (24%) branching pattern was the combination of 1 right intercostal-bronchial trunk and 1 left bronchial artery, and, secondarily (13.46%), the combination of 2 right (1 intercostal-bronchial trunk and 1 bronchial artery) and 1 left bronchial arteries. Seventy-eight ectopic bronchial arteries were detected in 59 cases (28.3%). They most commonly originated from the aortic arch (37.2%), the descending aorta below the level of T6 (35.9%), or the aortic branches (16.7%). The number of right ectopic bronchial arteries was significantly higher than the left ectopic bronchial arteries (50 [64%] vs 28 [36%]; P < .01). The incidence of ectopic bronchial arteries was statistically higher with men versus women (45 [29.8%] vs 14 [24.6%]; P < .05).
The origins, numbers, diameters, and courses of the bronchial arteries can vary substantially among individuals. Multidetector computed tomographic angiography enables a detailed road map of the bronchial arterial system to interventional radiologists and thoracic surgeons.
在本研究中，我们旨在通过回顾性分析因各种原因接受胸部多排螺旋计算机断层血管造影的患者图像，揭示支气管动脉系统的正常解剖结构和变异情况，并确定这些变异的性别分布。
回顾性分析了总共208例患者（151例男性；平均年龄59岁）的多排螺旋计算机断层图像，以评估支气管动脉系统的正常解剖结构和变异情况。
共检测到531条支气管动脉（中位数为3条；最少1条；最多5条；平均2.5条）。右支气管动脉的数量（平均直径）高于左支气管动脉（分别为290条[1.43毫米]和241条[1.26毫米]；数量和直径方面P均<0.05）。男性支气管动脉的平均数量（直径）高于女性（分别为2.58条[1.45毫米]和2.47条[1.32毫米]；数量和直径方面P均<0.05）。最常见的（24%）分支模式是1条右肋间支气管干和1条左支气管动脉的组合，其次（13.46%）是2条右支气管动脉（1条肋间支气管干和1条支气管动脉）和1条左支气管动脉的组合。在59例（28.3%）患者中检测到78条异位支气管动脉。它们最常见的起源是主动脉弓（37.2%）、T6水平以下的降主动脉（35.9%）或主动脉分支（16.7%）。右异位支气管动脉的数量显著高于左异位支气管动脉（50条[64%]对28条[36%]；P<0.01）。男性异位支气管动脉的发生率在统计学上高于女性（45条[29.8%]对14条[24.6%]；P<0.05）。
支气管动脉的起源、数量、直径和走行在个体之间可能有很大差异。多排螺旋计算机断层血管造影为介入放射科医生和胸外科医生提供了支气管动脉系统的详细路线图。
