目的 :为口外舌动脉结扎提供解剖学资料。方法 :在 30例经动脉灌注红色乳胶的成人尸体标本上 ,对舌动脉的起源、走行、分段和各段的重要毗邻等进行解剖观测。结果 :舌动脉单独起于颈外动脉者占 6 6 .7% ,与面动脉共干者占 2 3 .3 % ,与甲状腺上动脉共干者占 10 .1%。舌动脉起始处的外径为 (3 .4±0 .6 )mm。起点至颈总动脉分叉处的距离为 (1.1± 0 .5 )cm。舌动脉全程可分为 4段 ,即 :起始段、舌骨舌肌段、升段和水平段。舌骨舌肌段位置恒定 ,部位表浅 ,体表标志明确 ,血管周围无重要结构。结论 :舌动脉舌骨舌肌段是行口外舌动脉结扎最理想的部位。
Objective: To provide anatomic data for the ligation of oral tongue. Methods: Thirty adult cadavers with red latex were infused into arteries to conduct anatomical observation on the origin, course, segmentation and important adjacency of tongue. Results: Twenty-three to seven percent of the common lingual arteries originated from the external carotid artery, 23.3% to the facial artery, and 10.1% to the superior thyroid artery. The outer diameter of the lingual artery was (3.4 ± 0.6) mm. The distance from the starting point to the common carotid bifurcation was (1.1 ± 0.5 cm). Tongue arteries can be divided into four sections, namely: the initial segment, tongue tongue muscle segment, ascending segment and horizontal segment. Tongue tongue muscle segment position, surface superficial, body surface markers clear, no important structure around the blood vessels. Conclusion: Tongue tongue tongue tongue segment is the most ideal site for tongue ligation.
