根据90例(男:76例,女:14例)尸体锁骨下动脉及其部分分支之统计,有以下之初步结果:1.锁骨下动脉于颈部,高出锁骨上缘之平均距离为2.19厘米,及该点(锁骨上缘之点)至胸锁关节之距离平均长度为2.18厘米。2.锁骨下动脉移行为腋动脉时,并非在锁骨之中点通过,而在其中点之内侧平均距离为1.05厘米处通过。3.椎动脉、甲状颈干及胸廓内动脉(1例除外)均由锁骨下动脉之第一段发出;肋颈干在三段中均可发出,但左侧以第二段,右侧以第一段为多;颈横动脉同样可由三段中发出,但以第一段发出者为多见。4.甲状颈干分支类型共计18型,以第一、二型最多,应为标准型。5.肩胛上动脉起于甲状颈干或胸廓内动脉者,多在肩胛上韧带之上经过;起于锁骨下动脉第三段或腋动脉者,多在韧带之下经过。6.甲状腺下动脉行经喉下神经之前方者较后方为多,以左侧为甚,右侧前后之出现率几相等。
According to the statistics of the subclavian artery and its partial branches in 90 cases (76 males and 14 females), the following preliminary results were obtained: 1. The average distance between the subclavian artery in the neck and the superior margin of the clavicle was 2.19 Cm, and the point (point of the upper clavicle) to the sternoclavicular joint the average length of 2.18 cm. 2. When the subclavian artery migrates to the axillary artery, it does not pass through the midpoint of the clavicle but passes through an average distance of 1.05 cm inside the midpoint. 3. Vertebral artery, cervical trunk and internal thoracic artery (except one case) were issued by the first paragraph of subclavian artery; rib neck stem can be issued in three sections, but the left to the second paragraph, the right to The first paragraph is more; cervical transverse artery can also be issued by the three paragraphs, but the first paragraph is more common. 4. Thyroid neck branch type a total of 18 types, the first and second largest, should be standard. 5. Suprascapular artery from the thyroid neck or internal thoracic artery, mostly in the suprascapular ligament above; from the third subclavian artery or axillary artery, and more under the ligament. 6. Hypothyroidism under the hypothyroid nerve in front of more than the rear side, to the left is even more, the right side before and after the occurrence of several equal.
