摘要: 目的 通过 CT 血管造影 (CTA) 方式回顾性分析天津地区人群正常主动脉弓的形态学特点。方法 选择 2016 年 1 月—12 月在我院接受胸主动脉 CTA 检查的患者 142 例, 使用 GE 公司 AW4.6 工作站测量弓上分支的直径 及角度, 获得数据运用统计学软件进行分析。结果 头臂干(BCT)开口直径 D1 平均(15.2±3.0) mm, 左颈总动脉 (LCCA) 开口直径 D2平均 (11.8±2.2) mm, 左锁骨下动脉 (LSA) 开口直径 D3平均 (13.6±1.9) mm。BCT 至 LCCA 距离 E1 平均(4.0±2.5) mm, LCCA 至 LSA 距离 E2平均(8.2±3.7) mm。BCT、 LCCA、 LSA 与主动脉弓所成切线角平均分别为 α (29.5°±14.4°)、 β(40.3°±17.5°)、 γ(57.9°±21.6°)。Ⅰ型主动脉弓三分支开口中点连线成角 Ф 平均(144.1°±10.1°), LCCA 中点至 BCT 和 LSA 中点连线的距离 L 平均(4.5±1.2) mm。男性 D2、 D3长于女性; 在 19~40 岁、 41~60 岁、 ≥61 岁 3 个年龄组中 D1逐渐增大, 而 α、 γ 逐渐减小; 在 41~60 岁、 ≥61 岁 2 个年龄组中 D2、 D3、 E2、 L 均大于 19~40 岁年龄 组, 而 Ф 均小于 19~40 岁年龄组, 差异均有统计学意义(P<0.05)。结论 本研究得到正常主动脉弓上分支血管直 径和角度的数据, 可为腔内修复主动脉弓的各类研究提供数据支持。

Abstract: Objective To retrospective study the morphological features of normal aortic arch in population of Tianjin area by computed tomography angiography (CTA). Methods From Jan 2016 to Dec 2016, 142 volunteers undergoing thoracic aorta CTA in our institution were retrospectively reviewed. In each patient, 10 measurements were made in GE AW4.6 workstation, including diameters, distances, and angles of branch vessels of aortic arch. SPSS statistical software was used to analyze data. Results The diameter of the origin of brachiocephalic trunk (BCT) D1 was (15.2 ± 3.0) mm, left common carotid artery (LCCA) D2 was (11.8±2.2) mm and left subclavian artery (LSA) D3 was (13.6±1.9) mm. The distance between the BCT and the LCCA (E1) was (4.0±2.5) mm, between the LCCA and the LSA (E2) was (8.2±3.7) mm. The angle between the BCT and arch (α) was 29.5°±14.4°, between the LCCA and arch (β) was 40.3°±17.5°, between the LSA and arch γ was 57.9°±21.6°. The angle formed by BCT, LCCA, and LSA(Φ) was 144.1°±10.1°. The distance between center of LCCA ostia and line between center of ostia of BCT and LSA (L) was (4.5±1.2 )mm. Values of D2 and D3 were larger in male than that in female. In the three age groups of 19-40 y, 41-60 y and ≥61 y, values of D1 increased gradually, while α and γ decreased gradually. When in the two age groups of 41-60 y and ≥61 y, values of D2, D3, E2 and L were significantly larger than those in the age group of 19-40 y, while Φ was smaller (P<0.05). Conclusion The data obtained by this study on the diameter and angle of branching vessels arising from the normal aortic arch may provide support for various studies of endovascular repair of aortic arch.
