Detailed knowledge of the thyroid ima artery is essential for surgeons consequently we conducted an analysis investigating the arterial vasculature of the thyroid gland in 290 cases by dissection of formalin-fixed cadavers and by studying computed tomography angiographies.
Our study was conducted on 82 cases obtained from the dissection of formalin-fixed cadavers while 208 cases were computed tomography angiographies. The following aspects were observed: the frequency of the thyroid ima artery, its origin, course, and diameter. All were studied, comparing right to left and according to sex.
Following the study of thyroid gland vasculature on a number of 290 cases, the thyroid ima artery was discovered in 16 cases (5.52% of cases), from which 3.45% of cases were in male subjects, and 2.07% of cases in female subjects. Of these, 4.14% of the total cases were left thyroid ima artery, and 1.38% of cases were on the right, found only in female subjects. In 5.17% of the total cases, the thyroid ima artery originated from the aortic arch, of which 3.45% were in the male sex and 1.72% were in the female sex. In one case only (0.35%) in the female sex did the thyroid ima artery originate from the brachiocephalic trunk. In 2.76% of cases, the thyroid ima artery existed with a left-sided inferior thyroid artery originating from the subclavian artery, either directly or from a thyrocervical trunk.
The thyroid ima artery has proven to be one of the highly variable arteries in terms of its presence and origin and the knowledge surrounding it is useful for surgical interventions.
详细了解甲状腺下动脉对于外科医生至关重要，因此我们通过解剖福尔马林固定的尸体并研究计算机断层血管造影术对 290 例患者的甲状腺动脉血管进行了分析。
我们的研究包括 82 例来自福尔马林固定尸体解剖的病例，以及 208 例计算机断层血管造影术的病例。观察内容包括：甲状腺下动脉的频率、起源、走行和直径。所有这些都进行了研究，比较了左右两侧，并根据性别进行了比较。
在对 290 例甲状腺血管进行研究后，发现 16 例（5.52%的病例）存在甲状腺下动脉，其中 3.45%的男性和 2.07%的女性存在该动脉。其中，4.14%的总病例为左侧甲状腺下动脉，1.38%的病例为右侧甲状腺下动脉，仅在女性中发现。在总病例的 5.17%中，甲状腺下动脉起源于主动脉弓，其中 3.45%为男性，1.72%为女性。仅在 1 例（0.35%）女性中，甲状腺下动脉起源于头臂干。在 2.76%的病例中，甲状腺下动脉与左侧甲状腺下动脉并存，起源于锁骨下动脉，或直接起源于甲状颈干。
甲状腺下动脉是一种高度变异的动脉，其存在和起源存在差异，了解其解剖结构对于外科干预非常有用。
