摘要
目的 为临床上设计颈外动脉结扎术的切口 ,施行颈外动脉结扎术提供解剖学资料。方法 逐层解剖经福尔马林固定的成人尸体共 5 2具 ,暴露颈总动脉分叉的部位 ,测量颈总动脉分叉的水平、甲状腺上动脉起始部位与颈总动脉分叉的距离 ,观察颈外动脉分支的形状。结果 (1)颈总动脉分叉水平低于甲状软骨上缘者达 :(17 30± 0 0 4 ) % ,平均距离 (8 91± 3 0 6 )mm ;高于下颌角水平者达 (2 88± 0 0 2 ) % ,平均距离 (11 93± 0 6 8)mm。(2 )甲状腺上动脉起始于颈总动脉分叉处者 (2 8 30 % ) ,高于颈总动脉分叉者 (4 4 34% ) ,低于颈总动脉分叉者(2 7 36 % )。 (3)观察颈外动脉分支的形状大多为树枝状 ,5 6 6 %为丛状。结论 临床行颈外动脉结扎术时 ,如遇舌骨大角、下颌角水平的高位分叉 ,可适当向上延长切口 ,若仍存在暴露困难问题 ,可改行颈外动脉栓塞术。如遇丛状分支 ,可以在丛状分支的根部结扎颈外动脉。
Objective To supply concerned anatomy references for ligating external common arteries and designing incision.Methods Dissected 52 corpses treated with formalin,uncovered the furcation of common carotid arteries.Measured the position of the common artery furcation,the distances between thyroid gland ascending artery origination and common artery furcation,observed the shape of external carotid artery ramus.Results (1)(17.30±0.04)% common carotid artery cortch starting at the lower level of the upper border of thyroid cartilage, and the average distance was (8.91±3.06)mm. Upper the angle of the mandible was(2.88±0.02)%,(11.93±0.68)mm. (2)The thyroid gland ascending arteries starting at the furcation of the common carotid artery were (28.30%),upper (44.34%),lower (27.36%).(3) Most of the external carotid artery branches showing arborization, (5.66%) were tussocky.Conclusions When ligating external carotid artery is performed clinicaly, if there is the situation the perch embranchments of common carotid artery, doctors can extend the incision up suitably,if fails,can change his profession to embolize external carotid artery,if there is the situation of tussocky ramus,doctors can ligate the root of the external carotid artery.
