本文观察了成人、儿童、婴儿共100例气管的动脉。恒定者发自甲状腺下动脉、支气管动脉、甲状腺上动脉与食管动脉;不恒定者发自锁骨下动脉(14.5％±3.52)、甲状腺最下动脉(12％±3.25)、肋颈干或最上肋间动脉(8.5％±2.79)、胸廓内动脉(6.5％±2.47)与椎动脉(2.5％±1.56);个别发自甲状颈干(1％±0.99)、无名动脉(100/±0.99)与主动脉弓、右甲状腺下浅动脉或右肩胛上动脉(各0.5％±0.71)。成人管径为0.2～2.1毫米,0.6毫米以上的占半数以上。节段性气管支在气管外侧蒂经过中,大多分成气管动脉与食管动管。对气管动脉的行程及其与喉返神经和右迷走神经的位置关系进行了观察。气管周围动脉吻合丰富,节段性气管动脉沿气管外侧壁上、下连成气管外侧纵链,管径为0.1～0.5毫米,出现率为63.3％±8.80,借前软骨间横动脉以调节左、右侧血液循环。气管支在气管外侧蒂中,上下连成气管旁纵形吻合,以加强气管外侧纵链的侧支循环。在气管膜壁,后软骨间横动脉与气管动脉、食管动脉的膜壁支上下连成网状吻合。在甲状腺与气管上端周围的动脉互相形成丰富吻合,补充气管颈段的血液循环。气管胸段,支气管及气管支气管淋巴结周围的动脉形成广泛的吻合,以补充气管胸上段动脉与支气管动脉间的侧支循环。本文对气管动脉的形态特点、经过、分布及其与临床应用的意义进行了讨论。
This article examines adults, children, infants a total of 100 tracheal arteries. The patients with constant were from the inferior thyroid artery, the bronchial artery, the superior thyroid artery and the esophageal artery. The non-constant were from the subclavian artery (14.5% ± 3.52), the inferior thyroid artery (12% ± 3.25) (8.5% ± 2.79), internal thoracic artery (6.5% ± 2.47) and vertebral artery (2.5% ± 1.56) Aortic arch, superficial right inferior thyroid artery, or right supra-suprascapular artery (0.5% ± 0.71 each). Adult diameter of 0.2 to 2.1 mm, more than 0.6 mm accounted for more than half. Segmental tracheal pedicle in the tracheal pedicle through, most of the tracheal artery and esophageal tube. The tracheal artery stroke and its relationship with the recurrent laryngeal nerve and the right vagus nerve were observed. Tracheal arteries around the anastomosis, segmental tracheal arteries along the lateral wall of the trachea, the lower end of the trachea outside the longitudinal chain, the diameter of 0.1 to 0.5 mm, the incidence was 63.3% ± 8.80, the anterior cartilage transverse artery to regulate the left Right blood circulation. Tracheal branch pedicle in the trachea, up and down connected to the tracheal longitudinal anastomosis to strengthen the lateral tracheal lateral collateral circulation. In the tracheal wall, the posterior cartilage transverse artery and tracheal arteries, esophageal artery membrane wall branches connected to a mesh anastomosis. In the thyroid and the trachea around the artery to form a rich anastomosis with each other, to supplement the tracheal neck section of the blood circulation. Thoracic trachea, bronchial and bronchial bronchial lymph nodes around the artery to form a wide range of anastomosis to supplement the tracheobronchial artery and bronchial artery collateral circulation. This article discusses the tracheal artery morphology, elapsed, distribution and clinical significance.
