舌动脉生理状态下的临床解剖学研究

The study of clinical anatomy of lingual artery in physiological condition

目的:研究舌动脉生理状态下的起源、形态和行走,为涉及舌动脉的临床治疗提供解剖依据。方法:选择80例因临床疑有脑血管疾病而行64层螺旋CT血管成像(CTA)检查的患者,利用CT工作站的图像重建技术和图像后处理功能得到保留舌骨的颈动脉血管的三维重建图像。观察舌动脉起源、形态、走行,并对舌动脉的分段及舌动脉与颈动脉分叉、舌骨大角的关系进行测量和分析。结果:舌动脉走行变异较大,在舌骨大角处较恒定,舌动脉在舌骨大角上(2.32±1.29)mm、下(2.00±1.68)mm范围内,近似平行于舌骨大角水平向前入舌。舌动脉起始点到舌骨大角尖端水平之间距离为(10.40±5.75)mm,到颈动脉分叉水平的距离为(12.93±7.36)mm。结论:舌动脉在CTA上能清楚地显示,并能获得生理状态下的解剖学资料,在临床治疗中具有重要的指导意义。

Objective：To provide the clinical anatomy data in physiological condition of the lingual artery in 64- slices spiral computed tomography angiography （CTA） for clinical treatment concerning the lingual artery. Method：CTA examination of the carotid artery were performed on 80 adult volunteers. The 3D reconstruction images of the carotid artery with hyoid bone were obtained by using 64- slices spiral CT and image postprocessing workstation. The origin , pathway , and anatomic relations of the lingual artery in CTA were studied. The distance from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were separately measured, and the distance between the segment of the greater horn of hyoid bone of lingual artery and the middle of greater horn of hyoid bone were also measured. Result：The pathway of the lingual artery had high variation, but the relative position between the segment of the greater horn of hyoid bone of lingual artery and the greater horn of hyoid bone were relatively constant, The lingual artery run forward approximately parallel to the greater horn of hyoid bone into tongue （2.32±1.29） mm in the superior to the greater horn of hyoid bone or （2.00±1.68）mm in the inferior to the greater horn of hyoid bone The distances from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were（ 12.93±7.36） mm and（10. 40±5. 75）ram separately. Conclusion：The lingual artery could be clearly shown in CTA and the anatomy data in physiological condition of the lingual artery could be obtained by CTA. There was important instructive significance for clinical treatment concerning about the lingual artery.
