摘　　要：目的利用血管铸型标本和三维重建血管技术探讨胎儿甲状腺动脉的解剖结构及其应用价值。方法经颈总动脉和锁骨下动脉灌注填充剂,解剖观察及测量17例18~37周胎儿的甲状腺动脉;将CT扫描铸型标本数据导入Mimics 21.0软件进行甲状腺动脉三维重建。结果胎儿甲状腺上动脉可起源于颈外动脉第1分支(79.4%),或起源于颈总动脉(14.7%),或起源于颈总动脉分叉处(5.9%);胎儿甲状腺下动脉可起源于甲状颈干(76.5%),或起源于锁骨下动脉(23.5%)。胎儿甲状腺动脉分支及分布恒定。与成人甲状腺动脉相比,胎儿甲状腺动脉起始位置无明显差异;其分支及分布存在明显差异。结论了解胎儿甲状腺动脉的起始位置及分支分布特点,对宫内胎儿发育研究或新生儿临床手术具有指导实践基础。Objective To explore the anatomical features of fetal thyroid artery and its application value by means of cast blood vessel specimen and three-dimensional reconstruction technique.Methods The filler were perfused through the common carotid artery and subclavian artery,and the thyroid artery vessels of 17 fetuses at around 18~37 weeks were anatomically observed and measured.The CT scan data were imported into Mimics 21.0 software for three-dimensional reconstruction of thyroid artery.Results The variation of fetal thyroid artery originated from the first branch of external carotid artery(accounting for 79.4%)or originated from the common carotid artery(accounting for 14.7%)or from the bifurcation of the common carotid artery(accounting for 5.9%),the fetal inferior thyroid artery may originate from the thyrocervical trunk(accounting for 76.5%)or originate from the subclavian artery(accounting for 23.5%).The fetal thyroid artery branches and distribution were constant.There was no significant difference in the initial position between the adult thyroid artery and the fetal thyroid artery.There were significant difference in the branches and distribution between them.Conclusions Understanding the origin of thyroid artery,its branch and distribution characteristics can provide a practical basis for intrauterine fetal development research or neonatal clinical surgery.
