本文为小儿脉管系形态学研究课题之一。采用从初生到身长为150cm的童尸180具,分为六个组,对不同年龄小儿锁骨下动脉的起始、长度、外径和主要分支进行了观察和测量,着重反映小儿锁骨下动脉形态的年龄特征。结果表明:1.左右锁骨下动脉分别起始于主动脉弓和头臂干,偶见右锁骨下动脉起于主动脉弓。起始平面左侧以平T_3为多见,右侧以平T_2为多见;2.左侧锁骨下动脉起始部外径小于右侧,比值为1:1.06,左侧锁骨下动脉较右侧长,比值为1.24:1,侧差十分明显;3.椎动脉、肋颈干、甲状颈干和胸廓内动脉大多起于锁骨下动脉,两侧基本对称,其外径等测量值随年龄递增。
This article is one of the topics of pediatric vascular system morphology research. A total of 180 children aged from 150 to 150 cm were divided into six groups. The onset, length, external diameter and major branches of the subclavian artery in children of different ages were observed and measured. The subclavian artery morphology The age characteristics. The results showed that: 1. The left and right subclavian artery began in the aortic arch and brachial trunk, occasionally right subclavian artery in the aortic arch. The left side of the beginning of the subclavian artery is smaller than the right side of the outer diameter, the ratio of 1: 1.06, the left subclavian artery than the right Side length, the ratio of 1.24: 1, the side difference is obvious; 3. Vertebral artery, rib neck stem, neck and thoracic artery mostly from the subclavian artery, both sides of the basic symmetry, the diameter and other measurements with age Increment.
