本文对200例标本进行了枕动脉的起始部位的观察。枕动脉起自颈外动脉的占99.5％,源自颈总动脉的占0.5％。枕动脉可以独立或与其它动脉合干起始,分别占80.5％和19.5％。枕动脉起点在下颌角平面上下各10毫米以内者,占85.6％。比较枕动脉起始与面动脉的相对位置关系,以枕动脉起点较面动脉为高的居多,综合文献及本文结果,对教科书中所述“枕动脉起始正对面动脉发出”进行了讨论。同时测量了起始部的血管外径。
In this paper, 200 cases of specimens were observed at the beginning of the occipital artery. Occipital artery from the external carotid artery accounted for 99.5%, from the common carotid artery accounted for 0.5%. The occipital artery can start alone or with other arteries, accounting for 80.5% and 19.5%, respectively. The onset of occipital artery in the mandibular angle plane up and down within 10 mm, accounting for 85.6%. Comparing the relative position between the beginning of occipital artery and facial artery, the starting point of occipital artery is much higher than that of facial artery, and the comprehensive literature and the results of this article discuss the “echogenic artery of right occipital artery” described in the textbook. At the same time, the initial vascular diameter was measured.
