Because of the importance concerning angiography and approach in neck surgery the venous drainage from the inferior border of the thyroid gland, including its variants, had been reported in numerous times in surgical and anatomic literature. Statistical information on the frequency of opening sites and number of the thyroid veins are rather poor and differ with the variant authors tremendously, due to the small number of patients or preparations investigated. To provide more accurate data are the objectives of this paper. Our issues derive from examinations on cadavers of the dissecting-courses in the years 1987-1992 (n = 168). Preparations showing signs of semiresection of the thyroid gland had been rejected for this study, obviously. In regard to the brachiocephalic veins three groups of venous drainage could be established: A) Exclusive drainage to the right or left brachiocephalic vein or their junction, respectively; B) Combinations of the possibilities shown in A); C) Special cases with supernumerary drainage to other veins of the mediastinum. Besides detailed descriptions of the frequency of the variants found, the discrepancies to the known literature are discussed. Some of the variants described by us have not been mentioned at all.
由于血管造影和颈部手术入路的重要性，甲状腺下极的静脉引流，包括其变异情况，在外科和解剖学文献中已有多次报道。关于甲状腺静脉开口部位的频率和数量的统计信息相当匮乏，而且由于所研究的患者或标本数量较少，不同作者的结果差异极大。本文的目的是提供更准确的数据。我们的研究基于1987 - 1992年对168具尸体进行的解剖过程检查。显然，本研究排除了显示甲状腺半切除迹象的标本。关于头臂静脉，可以确定三组静脉引流情况：A）分别单独引流至右或左头臂静脉或其汇合处；B）A中所示情况的组合；C）向纵隔其他静脉额外引流的特殊情况。除了详细描述所发现变异的频率外，还讨论了与已知文献的差异。我们描述的一些变异情况根本未被提及过。
